I'm pretty sure the inverter is working but not the charger. When I'm plugged in, all the 12v stuff works ok. I have a voltmeter. One of my coach batteries was only 11. something volts. I had it charging overnight on the 2amp setting. I will check on it when I get home from work and if its charged, i will switch it to the other coach battery. One is 1 year old and the other is 2 years. My starting battery is brand new. I want to start my troubleshooting with all fully charged batteries.
Finding the 12V output wires on the converter may be a challange. I'm guessing they are not well marked.
What about the Onan generator starter. Would it get its power from the coach or starting battery? Im guessing coach.
Thanks for the info!!!
