There seems to be many reasons to cause the issue I'm having so I thought I'd make a post and pick your brains on it...

My 2000 Rancher 350 4x4 ES is having shifting issues. Last time I was on it I noticed a couple of times it didn't want to shift, or was slow in shifting, so it didn't really come on all at once. Right before I parked it, it didn't want to shift after I fired it up, so I shut it off and when I started it again I was able to shift it and be on my way. Yesterday when I went to run it, the ES didn't give me anything at all. Manual shifting is fine.

I'm worried it's something electrical. I've been having to clean up a mistake where the last owner had a staple in the fuse box and it's been causing issues. I found the volt regulator fried yesterday, I have to replace that and that part of the harness. Could the ECU also be damaged due to this as well?

I had but I wasn't sure it fit the bill since it had been running fine up until that point. I'll investigate though, it seems relatively easy to do.

You also need a good strong battery in it, fully charged, for the ES to work reliably. If you have a bad regulator/rectifier fix that and get the bike charging... then perform maintenance on it.

The wiring harness is in bad shape...I'm going to replace that along with the regulator/rectifier once they come in early next week. Hopefully the issue lies in the bad harness.
If the regulator is burnt out and disconnected, can that damage the ECU or will it just not charge the battery?

No matter how one attempts to answer those two questions (one sentence, two factors) there can be an exception... so you'd have to split that question in two and hope.... I'm not going there since we can't believe that the wiring harness is fit and proper.

I'd replace harnesses and regulator and anything else that looks questionable with OEM parts only, before testing for opens & shorts & functionality of them all (along with stator) in-circuit. Nevermind attempting to power it up until ya have gained some confidence in it.

I bought a 350es also and it was having the same issues. I found that the stator was in bad shape and had to buy a new one and it fixed everything.
