5500 Caterpillar. The generator works fine, but when we connect the coach to it, the GFCIs pop.
We’ve spent hours on the internet and have read about a neutral bond that needs to be disconnected on the generator because the transfer switch in the rig is already neutrally bonded. We tried that, but now we show low voltage in the rig, and when we test the outlets using a multimeter, there is current running through the neutral. We are going crazy trying to figure this out. Has anyone else experienced this? Any suggestions???
You say the GFCI's pop.
How many are there on your rig?
If more then one circuit protected, do they all pop?
Do other electrical items work- correctly when using the generator?
How are you connecting to the trailer, through the trailers 50 amp cord and adapters?
If so, then you are not using the transfer switch. The only way you could use the transfer switch is if you wired in a separate generator only receptacle.
How did you remove the neutral bond?
That generator should be wired internally from the stator to the frame - and should not be removed.
With it removed, the PCS should have locked it out for a missing neutral - ground bond.
Have you tried one of the simple circuit testers with 3 lights?

It is possible you have a different wiring issue either internally with the generator or the adapter you are using.
Hot - neutral reverse, Hot - Ground reverse etc

Actually, you need to bond the neutral and ground at the portable generator. R

Need to re-read it.
