vanwill52 Posted June 20 Share Posted June 20 I'm about to go on a 4-hour errand, so I wanted to post this before leaving. I'll return this afternoon. I'm planning to leave on a trip tomorrow morning. I have a 35 code, which simply says "Needs Service". Pressing the Start button from any of three locations does nothing. No click. No engine turn over. The lights---blink-blink-blink PAUSE blink-blink-blink-blink-blink, which I'm interpreting as Code 35. I'll work on it some more when I get back today.

jacwjames Posted June 20 Share Posted June 20 There are 3 fuses under the small access panel above the start button on the generator. I'd start checking those 3 fuses, I know one of them has to do with the starting function. I believe one is a 25 amp fuse and the others 10 or 15 amp.

vanwill52 Posted June 20 Author Share Posted June 20 Thanks, Jim. I only saw two fuses under that cover. I'll look again. Both fuses good. Oil and coolant were OK. Disconnected/reconnected the multi-pin line going to the genny. Link to comment Share on other sites More sharing options...
jacwjames Posted June 20 Share Posted June 20 (edited) On mine two of the fuses were attached to the neck of the coolant fill, the other was loose. When my wife was trying to get her's going late last month she found the loose one but the others were attached to the neck and at first glance didn't see them while we were doing a Facetime call.

Ivan K Posted June 20 Share Posted June 20 I hate to even mention it but isn't code 35 for self check failure on the control board? Maybe try reseting the connector? Wish it's something easier and cheaper than that. 1 Link to comment Share on other sites More sharing options...

Dr4Film Posted June 21 Share Posted June 21 @Ivan K is correct. C&P from the 7.5K Manual - CONTROL CARD FAILURE FAULT—CODE NO. 35 (Microprocessor EEPROM error during self-test) Corrective Action: See an authorized Onan dealer. Link to comment Share on other sites More sharing options...

FlightSystems.com. They are the experts on boards and board repairs and also refurbished replacements. They do, as of a member’s recent post, allow returns if issues other than the main board…. They also provide tech support to diagnose. Onan is good….these guys are better Link to comment Share on other sites More sharing options...
