Default FXR charging System



Reddit thread (first post in pic) says the fix for this is simply to hard wire with no plugs. The theory is that primary oil in the regulator- stator connection is causing an arc and fries the plugs. My problem is that I don’t think these plugs would fry unless there was a larger problem aka a short in the system. This will be my second time replacing regulator and stator in 4 years. Any opinions?? Thanks!!

I would recommend calling Cycle Electric

What I know for sure is that either old and deteriorated plugs or insufficient contact at the plugs can result in fried connections. Not a good design.

so yes I agree but this was actually a new regulator and stator set replaced not too long ago. Connection was nice and tight, used dielectric grease as well.

Cycle electric has a much better plug system than the stock stuff.

Word, I hear you guys and thank you for your help! I probably will go that route but don’t want to throw new parts again at a reoccurring problem. I guess my question is: Could the plugs fry like this from a wiring issue or is a bad connection the only way this could happen?

Good to do a physical check of your wiring for peace of mind.

So IMHO the problem is nothing to do directly with that connector! I've owned my 1990 Glide from new and replaced the stator once - it still works just fine! I suspect your connector has been fried by a persistent charging fault.

This 100%. .

Basically the connection has to shovel more amps than it technically can and gets fried in the process. The reddit fix might do the trick, but I don't believe the oil part is correct. Engine oil is poor conductor.

could bad rotor do this? I never replaced it
