no crank no start xj750

ive got a wiring mess of a bike i just got a battery for it and alot of spliced wires i turn the key and nothing moves ive got a few plugs not plugged in but for the most part everythings somewhere. i need help to get even just the gauge cluster to start, any ideas ?

 

Original fuse box with glass fuses? If so, the first thing would be to replace that with one of the blade type ones that XJ4Ever sells.

Make sure it's in neutral. The starter switch will not activate the starter if it's not in neutral.

 

im pretty sure its in neutral not entirly sure ill double check but nothing turns on no lights no cluster

 

Pics would help. Post 3 more times (nonsense posts in tis thread will do) and you can put photos in your post.
Im particularly intrested in seeing what the wiring at the fusebox looks like.

 

You should take the time to do those posts and get the pic on here.

If not, look around inside the bike wiring and see if you can find the mates to the connectors that are missing. Some could be missing a relay or diode pack (maybe).

As the others have states above, a huge no go issues is the fuse box that is stock on the bike. It needs to be checked over, cleaned and see if power is making it from one side of the fuse to the other.

Not too sure what your background is for wrenching on bikes, not too sure if you have the tools for trouble shooting. So let us know a little about your exsperiance and that will help us in pointing out what might help.

Good luck and get to posting a few more so you can get some pics up.

 

Im not too familiar with my bikes I started in automotive and am fairly comfortable and can turn a wrench but I know little to nothing about bikes

 

Fuse box is pretty busted it’s held closed with electrical tape and as far as fuses go it’s got 2/4 just for ignition and the signals

 

Electrically it’s a mess

 

That's a fire waiting to happen. No more starting her until it's fixed.
Your Fuse Box -- A Ticking Bomb??? By: Rick Massey

HOW TO: Install an aftermarket fuse box

 

I have yet to start her I turn the key and nothing happens no lights work unless directly powered so I’m thinking rewiring a good amount also is there any way to check if the ecu is good ?

 

Looks like some in-line fuses replaced the box fuses. I would rework all that with a blade style box for sure.

 

There is no ECU.
The only test that most people can do for the TCI is to swap it out, or sent it to someone who has the same model of XJ to see if it will fire their bike. I'm 90% certian that your wiring problem will solve the no-start issue, so let's start there.

 

I’m working on wiring it right now when I get some more done on it I’ll update you guys, thank you for the help

 

I found a blown fuse and one more missing I’m going to replace them and see how far that gets me

 

Watch the blown fuse. It blew for a reason.

 

I switched the fuses around and now the gauge cluster turns on so I need to replace that fuse but since that turns on the horn and turn signals also work still not cranking tho

 

So I fried this relay you wouldn’t happen to know the part number or what it’s called would you ?

 

That's the indicators self cancelling unit.

 

I doubt that it fried. The self-canceler is pretty robust, and has nothing to do with the ignition circuit.

 

I’m a little stumped I resurfaced all the grounds so they get a good connection and cleaned electrical connections with some electric spray and I’m not seeing progress I checked the starter button it has good continuity through the wires any idea that could help ?
