spark plug wire on Onan generator

[PaulC]

I found out why my Onan 7K gas generator wasn't running very good. There is a broken spark plug wire going to one of the spark plugs. Has anyone ever replaced spark plug wires? The one that is broken is the one on the left side of course, the one with the longest wire. I can't see where the other end of the plug wires go to. Anyone taken this project on before? Is it a DIY project or something best left for the pros? Thanks for any help.

DIY?

Depends on how handy you are. One end goes on the spark plug, the other end goes on the coil. Get the whole wire (both pieces)and go to a NAPA store, have them make you a new one. Should be real easy.

That is what I want to do but I can't get access or even see the coil end of the wire. It seems to be around the back side of the engine.

Time for an update regarding the broken sparkplug wire on my generator. I figured that I would try and temporarily repair it until I could get it into the Cummins/Onan dealer to get it fixed correctly.

What I ended up doing was to first slide a couple pieces of shrink tubing on one of the pieces of the plug wire. Then I cut off the broken ends nice and square. I took a heavy duty paper clip, straightened it out and cut off a piece about 2 inches long. I pushed about half of the piece of paper clip into the center of one of the broken pieces of the plug wire and pushed the other end of the paper clip into the other half of the broken wire. I covered the splice with a piece of heat shrink tubing and shrunk it down. I covered the heat shrink tubing with some electrical tape and then covered that with another piece of heat shrink tubing followed by another layer of electrical tape. I put the wire back on the plug and started the generator. Everything seems to work fine, even under load.

I don't think this is a long term repair but should allow me to use the generator until I can get it in and get it repaired the correct way.

Good job.

Results is what counts and it sounds like you got good results.

See no reason why your repair wouldn't last for a while, a few months or even longer.
