  1. Conclusion: With Kay's kind assistance we went through the system and determined that all is functioning as designed and batteries are getting required charge. Ready for the road now! Many thanks again to all who contributed !
  2. That is with both battery switches off and measuring from relay post to chassis ground terminal in left side of panel. With both switches on I read 12.78 from house side to chassis ground and 12.62v from chassis post to chassis ground.
  3. Good Morning Kay, Before I get started with the above tests I wanted to tell you about my latest weird happening. First I will explain that the step cover at passenger's seat is normally retracted with chassis battery on and extends when the chassis battery is switched off. Last evening after I took the voltage readings at the relay I realized that with chassis battery switch off the step cover did not extend but the ignition and dash instruments had no power. I did not think much about it since the relay had power on both terminals. I woke up in the middle of the night thinking about the problems and suddenly remembered that I had left both battery switches on. Then I began to worry that I might be draining the batteries as the shore power was also off (to eliminate the inverter/charger from the mix) so I got up and went out to turn them off (3:00 am) and as I did I heard the step cover closing. Switched chassis battery back on and cover retracts as it always has. Really getting curious now, I checked the voltage from chassis ground to both posts of the relay and NO VOLTAGE!! Still had 12v from neg terminal to positive terminal on the alternator. I just rechecked it to be sure I wasn't sleep walking or dreaming and I get the same results. I will now recheck for voltage at the relay posts with engine off and engine running and the ground back on the LE 415. Floyd
  4. I will get right on it in the morning if the weather will cooperate...lots of rain predicted here. Many thanks again for all your help!!
  5. I ran across these interesting photos of 2002 Monaco panels that are very similar to mine except for the item no. 7, relay, Bidirectional Isolator. Maybe an improvement? 1 Electrical Panel Passenger Side 2.pdf 1 Electrical Panel Passenger Sider 1.pdf
  6. I guess I had not noticed the discharge of the chassis batteries because I always plug in to shore power while parked .
  7. Took ground wire of LE415, no change. Same as before, voltage to both terminals of relay to chassis ground.😞
  8. Could this be related to the 12 volts I see across the alternator terminals when I should not have any voltage across the terminals?
  9. I just checked the voltage at the large relay terminals with engine off, 12.9 volts to chassis ground at both terminals. With engine running, 14.3 to both terminals.
  10. correction, should have been 0.3 ohms between the battery neg post and chassis ground.
  11. Rich, First I must thank you for being so thoughtful in getting me help in your absence. I hope all went well with your appointments. Now let me tell you how dumb I really am....I was taking alternator reading upside down and confused positive and neg terminals of the alternator. Rechecked readings correctly and now I read positive 12.6 volts between pos and neg post on alternator and 12.6 volts between positive post and chassis ground. Also, read 3 ohms between battery neg post and chassis ground. Hope this makes more sense but I lam still concerned that I get 12v across the pos and neg terminals as the tech tips says it should be zero.
  12. OK I checked the voltages at the alternator terminals: Alternator: There should be no voltage between the alternator + and – terminals either with the key on or off unless the engine is running. If voltage is present check the connections to the battery isolator and the functionality of the isolator if connected properly. With ign. off, I read -12V ., with ign. on, read - 12V Ignition Terminal: There should be no voltage to the ignition terminal with the key off. There should be 12V to the terminal with the key on (with or without the engine running).With ign. off, I read -0.311 V and with ign on, I read -12 V between ign terminal and negative alternator terminal and 12.2 volts between ing terminal and chassis ground. DUVAC Terminal: The DUVAC terminal requires 12V (coach battery voltage) to function, this functions as the “battery sense.” Depending on the application this may be 12 V with key on as some vehicles have a relay with the ignition system. I read 0 v with ign off and -.15 v with ign on. from duvac terminal to negative alternator terminal but I also read 12.8v between duvac and chassis ground. It is obvious the the negative alternator terminal is not grounded to the chassis.
  13. Rich is really a prince of a guy!! Yes, this does help me to get all of this into focus. I had just confirmed that the white ground wire going to the center terminal is connected to chassis ground and took resistance readings between the terminals of the green relay with the wires disconnected as instructed yesterday by Rich Today I got different readings from those given to Rich as follows: Pos test lead to center terminal and neg lead to lower terminal I get 0.59 m ohms, and with neg lead to top terminal I get "open". With neg test lead on center post and pos lead to lower post I get open, and with pos lead to top post also open. The trouble shooting info you referred me to refers to the Battery Isolator testing with ohm meter says I should be seeing zero or near zero ohms to both battery terminals with neg lead on center post but I am seeing the chassis post (top) as open. It also indicated that the terminal 1 (center??) should be connected to the alternator but my center terminal is connected to chassis ground. I am going back out to the coach now to recheck the voltage readings at the alternator as outlined in the tips.
  14. Excellent information! I am going to recheck "green relay" with ohmmeter and confirm the readings. I was curious as to why I would have the Lambert LE 415 as a charger when the inverter seems to be doing all the charging.
  15. Very interesting information. I wonder if I have the Bird relay. I am going to crawl around in the underside compartment where the inverter is located to see if I can find one. I have noticed for some time that the alternator light on the dash flickers with the voltage about 14v. I found that I could stop the flickering by turning on the headlights to add load and the voltage would drop to about 13.5v. Now wondering if all of this is related. Thanks for sharing this information.
