The converter is under the ref. as mentioned by some of the welcome responses. When I spoke to Bryan at Winnie it seems the three panels are backwards from what they show for this coach. Guess soeone read the plan upside down
The one 12 volt, Group 31 is cooked. Most likely not the fault of the converter, just a bad cell took it down.
I spoke to Trojan corporate and received a lot of help from their tech. ser. rep., nice people, very helpful.
I have spoken to the Trojan distributor nearest me and will be taking the coach to them to replace the 3 12 volts with 4 T 105, 6 volts. Quoted $98.00 each plus labor ($65.00 hour) plus new wiring as necessary. I feel more comfortable having them do it properly and being able to take advantage of warranty on the batteries if necessary.
I'm going to dig out the converter anyway just to check all connections.
Thanks for all responses. Mike
