Distributor problem


Rasken

Recommended Posts

Hi. 

After i put on my Yamaha r6 carbs on my Joyner 650, my distributor failed, it stopped working. Then i put in a new one, and that also failed. It happens when i run a few minutes at max speed, about 60mph. Its not the rotor or cap, its something else. 

So, is there something i can do to make it hold? What could be the problem? Or is it just bad luck? 

Is there anyway to rebuild the distributor to make it better?

Can I presume that you've verified that the coil is producing a spark and the plug/coil wires are not leaking?  I ran into a problem with my Suburban.  The plug wires were leaking high voltage.  You can seen the corona discharge around the plug wires in a darkened garage (easier to see at night).    Heat can cause the insulation to breakdown resulting in severe engine misfire especially under load or acceleration. That was my experience.

The coil works fine and I cant see any damage to the plug wires, i even measured them and all the values looked great. What happend is that the distributor directly breaks without a warning. I think it is those electrical things inside the distributor where it goes two cable to thats breaks. After changing the whole dist. everything works fine again.

      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL

      I have a Bennche 700 EFI Bighorn. I’ve recently been unable to get it to start. After a little troubleshooting I realized my fuel pump was not pumping fuel. This weekend I emptied the gas and replaced it with new. I replaced the fuel pump, fuel filter and fuel injector. I also replaced the battery, spark plug and made sure all my fuses and relays were good. I have confirmed that the float on the fuel pump is not obstructed. The UTV is about 12 years old and has less than 100 hours on it. It has not run in over a year.  Not sure whats going on?!? After doing a little reading I'm leaning towards it being an issue with the ECU or perhaps a faulty wire in the wiring harness. Anyone have any ideas on where to start looking or what I could be dealing with? Any help is appreciated, thanks in advance!

      My 2018 Hisun sector crew engine cut off after about 15 minutes run. There is no indicator of what is wrong, no error code just die and won't restart until it cool down. I notice that the fan is not running but the temp indicator is on low temp, no overheat indicator. I checked the radiator fluid, it is cool to touch.
      Cooling fans are working, I can hear it running once awhile if I can get the engine warm up enough.  Thank you for all the help.

      Less than 40 miles can barely start. Dealer is working with Hisun on a number of other issues on this UTV. Can not get clear info on the meaning of these E codes this is getting. Anybody have some clear info for me?
