Onan replacement PC board
Don’t fool around with that old PC board, get this new one. Go to Onan parts and find out why and how to get one.
Boost Solenoid
Are you relying on your original boost solenoid? 
Shame on you!! This circuit should be used every time you start your motor and on that day when your chassis battery takes a dump, you will be happy you had a new one. Only $35 and it fits exactly.
Battery isolator
When this fails, you do not charge your batteries, is that important to you— well then spike that gun and replace it before you have a problem– I know it’s scary but why not plan ahead! A little bigger than original 2 holes line up and the unit is still small enough to fit in the original location. $65 puts this important part in your hand.
LED readout Systems monitor retrofit
Tired of wondering if that needle on the old systems monitor is really telling you something? Tired of walking into a pile of doodee in the bathroom floor because the holding tank was full and you washed too many dishes? Go to Systems Monitor for more on this part.
Alternator light circuit kit
OK, this is not an option– you have to have this or else! Your coach is at risk, at risk of melting the chassis wire harness from within. We here at the Co-op want to help you and to that end offer this retrofit kit to repair the wire harness problem. Read about the Alternator light circuit repair kit. There you will find a full explanation of the wiring problem and complete instructions on how to repair it. The parts are available at your local Radio Shack or we will send it to you for only $10.
Make it yourself or get it from us, but do it. OK, you have been warned, don’t dry to us when we have to charge you many hundreds of dollars to repair your wiring harness when it could have been saved for only $5. Tough words but this is important! I hate people who use “doom & gloom” when talking about products but I’ll risk being one for this issue. NO, a diode in line to the alternator DOES NOT bypass the circuit, you MUST bypass the issue all together and that is what I am telling you to do—- OK,OK, I’ll shut up now.
