|Generator woes (please help)||Shawn E. Frye||8-2-02|
|Hi, I have a 1978 31' Dodge Explorer RV. I'm not sure of the Onan model number generator that I have, but when I bought the RV... it was up and working fine. One day, I accidently hit a fence, and I tore off the generator door cover which also caused the fuel pump to bust off of the generator. I was not able to find a replacement pump (OEM), but the auto supply sold me a direct replacement. I put this fuel pump on.. and now the generator will run for no more then 3-4 min. before cutting off. I replaced the fuel pump with an even better model, but it still only runs for 3-4 min. before cutting off. |
Basically, I was wondering if maybe there was something else on the broken fuel pump that might have kept the generator running and/or any other tips suggestions you guys might have.
Thanks in advance

|The first thing that comes to mind is the low oil pressure cutoff. Possibly when the fuel pump got torn off, it pulled the wire and damaged the switch.|

|You might have debris in the needle and seat of the carb on the generator. Happened to me once too and found something very small like rubber clogging the needle/seat.|
Are you in the Dallas Ft Worth area, I make house calls.

|I have a 1977 Executive on a Dodge chassis and a 6.5 Onan Generator. Had similar problems It would run about an hour then stop. Each time I started it after it was warm it would run only 10-15 minutes. I installed a clear inline fuel filter and saw that it would fill full of air (or vacumn)and restrict the amount of fuel getting to the fuel pump. I'm still working on it. But the last time I had it out it ran then after a few hours stopped. I disconected the fuel line and let it drain till the inline filter was full of fuel. Started it up and it ran a few more hours. |
I've read on other boards that the oil flow switch could cause this type of problem and the fix was to jumper out the switch. This sounds risky and besides I couldn't figure out how to get to the switch.
Hope this helps.
