So I have a Bennche Bighorn 500 that I bought used a couple years ago. Was working fine until this winter when I was plowing and I think it drained the battery. And had a difficult time starting and staying running. Idle seamed really low, and would only stay running if I pushed on the throttle. So I changed the battery, and the acm valve, fuel filter and spark plug it will start up and surgery to 3k rpm but comes back down and dies, unless I give it throttle. I am getting fairly good amount of fuel from fuel pump. It does spit at stutter right before it dies. What should I try next?
I have a Coleman 550. Was having problems to start with where it would start and then shut off after a couple tries. It would take off and be good. It then got to a point where it would not start at all. I replaced the fuel injection twice the second time I replaced it I noticed a mouse or something had chewed one of the wires that connect the electrical to the fuel injector. . So two-part question first does anybody have a part number for that wire harness? Second, any other ideas after I fix the wire harness permanently on what could keep it from starting I have gas flow up to the fuel injector.
I realize this part is discontinued but im trying to find this exhaust pipe fir my dads 550. His brother who has since passed bought this mule for my dad who is now 90 and he is trying to fix everything on it. I'm willing to take a used one. A new one would be great if someone still had in stock. I'll take anything as long as it is in workable condition. If anyone has any ideas for me im open to hearing them. Thank you so much.
Have a MSU 500 that we got from my wife's uncle a while back. We've had it running and hauling around the property but it stopped a few months ago after what I thought was running out of gas and I'm just getting to looking into it.
Had fuel to the injector but nothing coming out the injector so swapped with new injector and installed inline filter in the supply hose from fuel pump. Tried again and still nothing but noticed this time that I can't hear the fuel pump priming.
Pulled off the electrical connection and I'm getting 12V to the fuel pump but it won't run. Put it on a test bench and got it to run so put test lamp between +ve and -ve terminals on the connector and nothing. Checked against the passenger seat securing post and get a light.
Tried chasing the wire back and think that the ground is through the ECU but not 100% sure. Can someone confirm for me? And if it is through the ECU, is the ECU just grounded against the frame or is it wired through to the battery?
Thanks in advance and hope this all make sense!
