    I would expect that generators from your vintage have mechanical governors which are less responsive to speed changes than todays electronic/digital governors. It would be interested to know what the frequency was you were experiencing the problem.

    I combination of low voltages and low frequency is definitely a problem for induction motors.

    I'm getting the Samsung RF18. I think that is the one he meant. It will replace my No-Cold 1200. 

    Very well could be a RF18.  We have been on the road for a few week and have been traveling in some hot weather, couldn't ask foe anything better.  The rig is parked in El Paso while we are in Juarez visiting our son.  I checked on it yesterday and refrigerator was 36 and freezer was -2, daily temperatures have been hovering around 100,

    Rick,

    My issues are with my tachometer not the speedometer.

    Looks like some us signal from alternator and others a pulse generator.  I assume that mine uses a pulse signal because there is a label on the tach housing that it is calibrated for 12 pulses per revolution.  I'm trying to data and location of the proximeter that provides signal to tach.

    I will call REV Group when I arrive at my destination,  I just started a 5 week road trip and it failed on the first day out.

     

    Thanks

    Jim

    No signs of damaged wire in dash behind instrument cluster.  My drawing on show  tack leads connected to terminal #1 on Tach and going to two connector plug with onlt grey wire coming from tack.

    Information on tack that is visible without removal indicates tack was calibrated for 12 revolutions.  This would suggest that the tack input comes from proximity probe.

    I will contact REV group tomorrow.

    In response to Cabbage Hill, cruising was 45 MPH

     

    Thanks,

    Jim

    The Tach on my 2004 Holiday Rambler Endeavor with Cummins ISC failed when cruising down the road.  All was fine cruising up Cabbage Hill grade in eastern Oregon and smelt slight odor, look down at instrument cluster all good except tachometer was reading "0".

    Anyone have experience with failure of tachometer,  I assume signal is from engine ECU.

    I believe the instrument cluster meters are manufactured by VDO. Anyone have any experience or lead on repair facilities?

    Thanks,

    Jim

    I would check the glow plugs to make sure all of them are working properly, all check electrical connections. I found the main positive battery lead connection on the outside rear of the generator enclosure severely cooroded, cleaned connection and generator started much better and cranking speed was faster. I contributed the corrosion to the salt that is used for deicing roads during the winter.

    You will need to disconnect the common buss that power each glow plug, they are all connected in parallel. You can check each glow plug with a 12v test light, connect test light clip to 12 v positive then probe each glow plug for connunity, test light will illuminiate if glow plug is good.

    The closest campground to the park entrance are in Ashford and Packwood, WA.

    The campground are small independent campgrounds, not sure what size RV's that they can accommodate.

    If you want to travel a little further to park entrance there are some nice RV parks on Lake Scanewa and Rife Lake which are located in Cowlitz River valley.
