Tom,

I kind of thought you had a single alternator. For simplicity, you
may be further ahead to just do the cut-off that separates the gen
supplying the inverter/charger and chassis while running at the same
time as you first mentioned. Or you could disable the charge function
on your inverters when on the gen while driving and just let the
alternator take care of the both the house and chassis. To solve your
concern over losing an inverter, you may want to think about an
inverter by-pass.

I forgot, who’s on first!!!

Do these 4024 have an internal auto-switch? If they do it sounds like the previous owner was relying on them to do the switching. Maybe it worked and now the inverters internal auto-switch function has gone bad.

I told you guys this thing was complicated!!! 🙂 Greg, the auto switching in the inverter from shore power to gen set works as designed. The issue comes if I run the gen set and the bus alternator at the same time.

By the way I did not intend to steal this thread. Have we helped the orginal poster with his problem???

Gran is probably still researching his problem, but don’t worry about hijacking the thread. Both you and Gran are dealing with something of interest.

If you wish to continue educating us as to your progress feel free to start another thread if you wish, but both of you are dealing with indicator lights. You never did indicate the output from the inverter chargers with the generator running but the engine off. Something is lighting your lights.

BTW, the balance light is supposed to come on if the 12 volt voltage is outside of 50% of the 24 volt voltage by greater than 1/2 volt (roughly speaking).

Have the same issue with my coach with gen set and motor running before I got OTR working. Light would flicker when engine and gen set running. I would isolate battery bank and light would go out. I have 2 vanner chargers in engine bay.

Glen,

Two Vanner chargers in the engine bay? Could you elaborate a little more on that?

I don’t know which model year it was, but sometime in the nineties Prevost switched from a pair of 50 amp Vanner Equalizers to a single 100 amp equalizer. I don’t think anyone replacing a defective 50 amp unit can even get one so it is likely the fix will be a 100 amp to replace both.
