03 rincon 650 electrical issue

I got a 2003 rincon last week and it seems that every time get it running it runs great but as soon as I touch anything that needs power it shuts off! And I gotta pull start it at the moment cause I just ordered the starter and clutch for it but this electrical stuff is my weakness I’ve checked all the fuses and the connector between the battery and the fuse box. And it only seems to do it right after I run through some water. I have another issue with it not wanting to go in gear after this happens and it wants to idle really high and I can’t bring it down anymore any advice on where to look would be helpful!
