rfsod48, Welcome to the FMCA Forum! You did not post the shore power wiring of your coach, having said that I do not think the use of an auto transformer on an RV would be practical, cost wise for the number of times one might need it. Plus the size and weight of one large enough to supply the current could also be an issue. The cost of running a generator when there is a low voltage situation might be a better option. The normal applications are motor starters, dimmers, static balancers (for voltage) Rich. If you are want some technical information on them - try this link. http://nptel.ac.in/courses/108106071/pdfs/1_11.pdf

cmturner, Many items can be repaired! Could you post a pictures of the area in question(close up image of the hole would be helpful) and I could post some information on material that might solve the problem. Also, not knowing what your tool availability and skill sets are-that information would also be helpful. Rich.

Thanks Kay ! Now I'm going to have to place fuel theft springs in the filler lines!! Ah not really in our case as the fueling points are locked up. Never got wind of that trick while growing up, but most people respected others personal property!! Raised in an area of the county where many had to go into the woods to get meat for the table and some slime pickings on the table some days. Rich.

First - Eliminate the possibility of battery issues(All Connections) Typically the generators start off the Chassis batteries, but the start circuit could be connected to the coach batteries. The fact that your coach is a 1998 - there is a good potability of a defective ground connection for the starting circuit. The common practice is to use the chassis frame rails for the ground circuit. These connections tend to get very rusty over time and it would be less expensive to repair a connection or replace some wire or connectors then to R and R(Remove and Replace) the generator with a new circuit board, parts and labor. Should R and R not cure the problem and there are bad connections or batteries, you would still have to add that item to the repair cost. Has the service center checked all the Generator DC circuits to make sure they are in order? Ask what the starting voltage is at the generator when starting, and what the resistance readings are between the generator DC starting connections and the battery connections for the starting power supply. One could have the service center disconnect connect the battery used to start the generator at the generator and jump in/connect a battery to the starter connections. Start and run the generator to see if the issue still is present. Have them test the system this way outside where you can see them run the test. If the problem still exists then you need to make a decision. 13 code is related to charging circuit and yes it could be a defective board , But the fact that it runs for 10 min.. could mean there is a defective board - that has issues only after it heats up or there is some other issue. This test should narrow down the possibilities. Note- They should be able to easily monitor the battery voltage level this way and you can also see the test results directly. I like to eliminate any and all possibilities before spending what will be a considerable amount. Hope my thoughts help you decide what way to go / Rich.

Code 13- Check all the battery connections and grounds / check battery conditions(of all the batteries) How old are the batteries? for both the coach and the chassis? This code is set when when the regulator can not sense the proper voltage. What are the voltages when the generator is not running and what are the voltages with the generator running? Would be good to check all the battery hydrometer readings. Rich.

Larry, do you know if you have an ISB-02 engine ? This series has a third filter installed along the drivers side frame - just behind the rear wheels and is very hard to find or see. The only series engine with this 3rd. inline filter. and around the correct year. The information was issued in a separate PDF file and it gets missed at many of the service centers. Rich.

crb13563, And, welcome also! Could you post the service information for the group. When where the filters,oil,fuel filter engine oil and coolant changed ? Are there any codes you are reading? What is the states of the coolant level? Have you just changed it? If you just changed the coolant there is the possibility of an air bubble in the coolant system-you might need to burp the system. The other possibility is the Spark Arrester needs to be cleaned. Manuals-981-0160=Owners Manual 981-0200D=Parts Manual 981-0522B=Service Manual Model number 8HDKAK (1145C)? What inverter is installed in your coach as per Brett's post ? Question- Does the inverter work when connected to shore power? Rich.

Joe, Turned out real nice. The new one dresses up the area !! Rich.

fdperai, I think this is the link to the Owner / installation manual for your Generator. http://www.cumminsonan.com/www/pdf/manuals/900-0541B.pdf Rich.

Marty, The removal of the Generators can be challenging. Think that if you do not have the instillation manual with you paperwork that this link might be helpful. Page 22 list the models and the different manuals you can purchase. Not all installations are the same or the space where they are mounted. So this makes each instillation a little different. http://www.cumminsonan.com/www/html/Common/pdf/rv/F-1123.pdf Think that if you can reverse the instillation process and the proper equipment you can get it to where you could work on it. Label all the wiring, fuel lines and anything that you need to remove - this helps when reinstalling. Also plenty of pictures before removing items comes in real handy. Rich. This link and information might help with some information on the mounting. http://www.cumminson...s/900-0541B.pdf

rlbarkleyii. This is the only information that I have regarding the 9100 - hope it is helpful. http://www-odi.nhtsa.dot.gov/acms/cs/jaxrs/download/doc/ucm442997/rcorrd-13v357-1444.pdf Rich.

JT, Are you able to get under the coach SAFELY? With the parking brake set "please" and spray some soppy water around the area you hear or think the air is escaping. Should see some bubbles form or bubbles popping quickly it there is a bigger leak. Not knowing what items have been serviced, in regards to the air compressor drier filters and how often the manual air bleeders have been pulled to vent off any water buildup in the primary and secondary air tanks, makes it difficult. So could you post all of the service that has been done on the air brake and air ride systems for the group. One seemingly unrelated question, how long has it been since the engine air filter and intake system have been serviced? Rich.

Evaporator would be on a 25 to 30 amp circuit and the thermostat would require much less current. Think the wire gauge and connector sizes would be different sizes also. Rich.

JT, Your getting close to needing a haircut, are your pet clean shaving? LOL Your wiring is not connected to the ignition switch from what I have on file. So it looks like you can engage the air ride before or after you start the engine to fill or dump the Air Springs. Air Ride wiring- in cab-Connector Pin #1==Green wire to dump circuit-wire at valve is Light green Pin #2==Blue wire to fill circuit-wire at valve is light blue. Only the Green and blue wires at the valve connection-2 pins Pin #3==Black / Ground point inside cab. Most likely at the common dash grounding point. Rich. Note- from the drawings it looks like the Engine neutral safety switch and the park brake need to be providing a ground for the Start relay to engage. The Chassis builder may have added a slide(s) IN switch to the sequence before the engine will start?

fdrperai, Welcome to the FMCA Forum! Could you post the model of your Onan and the make an year of the coach for the group? Rich.

JT, Could you post the Make, Model and Year of your coach, also the chassis manufacture. On my coach you need to have the switch in auto when starting or the air ride will not air up. There are different wiring setups regarding the air valve operation that have been used over the years. Rich.

Dacar, With the price tag being what it is and the lack of any signal specifications found yet, personally I would hesitate. This is a link to a PDF file on use and installation that might help. Think you will have to copy and paste it into you browser. http://wilsonsignalbooster.com/media/wysiwyg/Products/Amplifiers/Sleek-4G/Sleek_4G_Installation_Guide_813426.pdf Rich.

Did you have a switch replaced or repaired also? Rich.

Gary is correct- The cover is about 1-1/2in. in diameter and for your model year freightliner chassis - it is to the left of the steering column. Rich.

bostonbernie, Welcome to the FMCA Forum! Questions-How long did the coach set before you started it? and was it damp and or raining? First thought is a spark plug wire, that might be real close to making contact to a ground point. Think you might want to look at the spark plug wires and there location, if a wire is resting on a hot surface-this can melt or damage the insulation. when the wire got damp / an ark can jump from the damaged area to ground. If you have a real dark area where you can park the coach ,open the hood and look for an ark - or you might see a blueish glow - it will be very faint, so the darker the better. If there is a glow (Corona) there is a bad spot in the wire(s). That is my first thought. Rich. Note- if there is a bad spot in one of the plug wires and you get to close or touch it you will be picking your self up off the ground in most cases !!!!!

Joe, Went to a wedding in FL a few years ago, and every time we started the GPS it would calculate a different Route. So, between the rehearsal, setting up the reception, going to the wedding and on to the reception we got to see a different part of the county on each trip. LOL It kept things from getting boring !!! Rich.

wef90, When the key pad lit up, did you try to start the engine? When you call Freightliner factory service you will need the last 6 characters of the Vin. number. They are located in Gaffey SC. Good people that will do there best to get you some good information! CUSTOMER ASSISTANCE OR CONCERNS Contact our Customer Support Center at 1-800-FTL-HELP (1-800-385-4357) Factory Service Center Freightliner Custom Chassis Corporation 552 Hyatt St. Gaffney, SC 29341 (phone) 864-487-1700 Thanks for the feed back. The one item that gets many of the coach owners and service centers, are bad or intermittent grounds. Your Cat ECM ignition signal connects to pin 70. There is a connection from the same wire to the Grid heater and that goes through a Diode-They can be problematic. The signal will pass through a relay that is powered when key is in the start position (if memory survives my correctly) With your setup the transmission TCM is in the start circuit - looking for a park brake signal,transmission in neutral signal and it could be going through a circuit that is verifying that the slid(s) are in-Jacks are up. The wiring changes form time to time and model to model. Rich.

wef94, Welcome to the FMCA Forum ! Brett, got his post in before me so lets see what you find out. Is you coach model WKP36G or WKP36SG ? Rich.

demetropoulos, Welcome to the FMCA Forum! Could you post the model number of the OEM pump and the model of your current pump? Then the members can compare the specifications and see what might be the cause of your issue. Need a starting point. Rich. Question, do you know what the current rating of the latching relay is for your water pump? The new one might be drawing more current an that might be causing the surge issue>

Link Repaired for Air tabs. Thanks- Edited by tmoning, Today, 01:14 PM. Fixed Airtabwebsite link Rich.
