12 volt to 120 volt ground
I've got a 12-volt light above the passenger seat that does not have a good ground. The positive side of the light is getting good voltage and it works when I manually ground it. I removed the light...

Where do you think the 120 Ground circuit has its final ground? AT the chassis frame. What do you think could possibly be a problem with using the 120 ground for a 12 volt light? Nothing! Doug
I've seen cases on other equipment where someone connected the grounds together and shorted out the rectifier. Not sure if a MH converter would do the same but why take a chance.
Also the ac neutral is not to be bonded to the chassis ground in an rv.
