Thank you ALL! The aggregate of responses will lead to my next step (s). And confirmed at least one thing re my mechanic input (who insists that second battery is part pf the starting circuit – I’m getting the rig back today to look further). I brought it to them for brakes, which they did a great job on, but then the charging issues commenced – after they finished on it - followed by them suggesting I needed a new alternator (which I let them replace)….followed by more charging issues which they now indicate they are not comfortable solving. They advise the PCM is now bad. From Dodge/Cummins forum, I’ve read that improper trouble shooting can fry those. Not throwing stones...I’ve been patient….just need to figure out.
“ScottG” thank you especially for your clarification. One battery to start is what I suspected and I’ll now go to the Cummins/Dodge forum to confirm, and get my pics. There has never been a separate house battery in the RV coach portion so that second battery must be for house needs only (not starting).
“Bgum”, Thank you. This is the first I had heard about new company taking over Scotty – all previous input I’ve gathered suggested that Serro plant burned down and business closed. I will pursue your lead.
Appreciate all. As far as a suitable mechanic in this case, I’ve not had a lot of luck. Best electrical Trouble shooter I know (done some amazing stuff on my 98 Saab 900 S), doesn’t have the space set up for RV – but he might take a look in a couple weeks. Current mechanic obviously struggling.
So – one more request. Would appreciate group input on the following:
Would you suggest (if I can’t solve on my own – with input above):
1.) Dodge dealer (not sure their mechanics will have experience with ’92?)
2.) Cummins dealer/service – I’ve seen that they work they work on Class A Diesels…not sure if my Class C is a good fit
3.) A general RV service shop (who understands starting vs house batteries – but maybe not the uniqueness of first gen Dodges as modified by Serro for RV)
Thank you!
