Was left stranded, XJ750 Seca no power to anything need help.

Took a good look at how the PO put in the inline fuse holders and to my surprise was done properly soldered and heatshrinked

 

Ignition switch looks really new. contacts and all internals were super clean. I believe this is a Maxim style ignition switch, would that cause a problem with my bike being a SECA model?

 

po could have done bad job soldering or just twisted wires together cut back the heat shrink to find 3 live feeds from brown wire.
if you get no voltage after that you may have to unwrap harness tape to find splices to brown wire .
all 3 failing I would clean and inspect the key switch first

 

Right I have already cleaned ignition switch and contacts. it seems really new. Guess now I have to find where the hot 12v brown wire splices off. It doesn't appear to be in the headlight bucket mess. Will do it bright and early tomorrow as it is dark already.

 

it splices someplace inside the main wiring harness.

unfortunetly that same brown wire goes to computer monitor and alternator and rectifier.

 

when you pull the ignition switch put a jumper wire from red to brown on the harness connector that goes to the switch see if you have power at fuse

 

Yeah I had put everything back together after messing around with the fuse wires and ignition switch wires and noticed the red (or brown i forget) was melted on the connector. I cleaned the connector to the best of my ability and everything electrical works now. I have ordered some new connectors and will do it up professionally when parts are in. Today I wired in a new voltage regulator and tomorrow will upgrade the fusebox. hopefully electrical will be done and I can move onto new brakes.

 

update: New regulator I ordered was defective (should of bought from xj4ever ) for fun I hooked up the old voltage regulator and cleaned / fixed all melted charging system connections. with a new multimeter seems like 14.8 is the max charging volts when revving the engine which is in spec. Removed alternator cover and cleaned the copper rings and the 2 brushes were in spec. How important is the gasket that goes in between the cover and the engine? should I remove all gasket material and replace or just leave it? pic is before cleaning

 

That gasket's main job is to keep water out of the housing. I wouldn't run that cover without one but it's hard to tell from your picture what shape yours is in. If it's in one piece then I'd say run it. you can put a little sealant on it, make sure you don't block the weep hole at the bottom as this allows any moisture that accumulates in there.

 

This here along with cleaning usually fixes many charging issues. You can buy just the connections and replace them. I will usually crimp and solder these followed by some heat shrink. Pic is just for reference, might not be the correct part.
