hi david, welcome to the forum and you found the right bunch to help you out.

what i would suggest is work on one or two things at a time to avoid getting overwhelmed. i previously had a 1990, coach 236 and did almost a total restoration on it so i know them pretty well. another member of this forum now owns it.

i would start with the air system. you need to figure out what is causing it to not air up. there is lots of info here about the air system and how it is plumbed etc.

the kohler 12.5kw yanmar was the standard then. both are easy to get parts for.

if the coach has been sitting for many years, i would at some point do a complete service of engine oil, filters, fuel filters etc. both engines...but no need for now.

the genny runs, that is good. there should be a manual transfer switch up on the overhead console. just be sure it is in the position that allows the genny to power the coach. it will have 3 positions. shore off genny

there is also a breaker or fuse on the genny head at the back of the yanmar. make sure they are not tripped and good.

one way to check for air leaks is to plug into your coach an airline from a compressor. there should be a port in the passenger side engine bay. air leaks are something that we all deal with and you can start isolating the leaks to figure out where the big one is.

the best way is to ask direct questions

thanks
