  1. Actually, nothing in your coach works on 6 VDC.

    Those 6 VDC batteries are wired in SERIES, so two in series make 12 VDC.  Just think of it as a "12 VDC battery in two pieces".

    And, if four 6 VDC batteries each pair will then be wired in PARALLEL.

    This is a very common battery bank configuration.


  2. Ya, best "low speed control" vehicle I had was a 1966 GMC PU with V6 (ya the 305 CID HD truck engine V6) and a granny 4 speed.  Did a valve job on it, and the heads on that V6 were heavier than a 427. Can you say 0-9 MPH in first gear. Bought it for $125 in 1976 with a broken front suspension (right front wheel horizontal) and gore hole in passenger's door from where a bull ran into it.  Spend another $150 and Dianne and I drove it from Houston to Haines Alaska in 7 days.

    Yup. I have been dealing with this for about 2 years. I did find a bad ground and repaired it but that did not correct the problem.

    With this in mind, have you checked voltage at the pump when someone activates the leveling system. Yes, it sounds like a hydraulic issue, but verifying that voltage at the pump stay above 12.0 VDC is a reasonable, quick check.


  4. OK, if you just park it and do not dump air OR deploy jacks and one side goes down over time, there is a slow leak in that side's air bag, line to ride height valve or the ride height valve itself.

    Soap in a spray bottle will likely show the leak.  If going under the coach, make sure you have safe clearance (like drive the coach up on 2X12's) or use safety stands.


  5. I have NOT worked on an Onan carburetor-- but have on lots of other one barrel carbs (think Solex, SU, etc).  Very likely the idle circuit is different than the load circuit-- at least they are different on automotive carbs.

    Hopefully someone with hands on Onan carb experience will chime in.

    If all the fuel related responses do not solve your problem, you may have the some thing I experienced about 3 years ago. Same as yours, the generator would start and then die. Finally took it to Onan and found the engine temperature  sensor had broken. Replaced and started up immediately! Sensor is at the right rear of the engine on top of the coolant manifold. Technician stated that Onan had experienced a lot of the same failure.

    Was this temperature sensor on a gasoline Onan genset  like the OP's or a diesel???
