minimum wiring diagram

XJ750 Seca neutral light wiring doesn't interface with the "computer." The (light) brown wire is fused power and sky-blue wire is grounded by the tranny switch when in neutral.

Edit to add: same color code for XJ650 Maxiim.

 

Hey guys. I did this and have no spark. The only questions I have about it is the wires from the ignitor to the coils. Mine didn't have gray and orange wires coming out of it. It has a blue and white. I tied the white with the grey and the blue with the orange. This is correct right? I haven't found where anyone has made comments about it. Also my ignitor gets rather hot and so does my grey wired coil. Only getting about 3 volts of power on that side. Any ideas?

 

I am have really bad problems with the wiring on my 1982 Yamaha xj750 maxim and I was want to know if anybody was done there bike like this or is it even doable thx u

 

Mine was done based on this diagram.

 

Ok I did the wiring just like the dieagram showes and now my bike won't fire I think it has something to do with the tci box and iam stuck what wire should.be hook up Igot the wires going to coils and the pick up on it but there is a black and whit on the plug and a blue on and a black and red doses thoses need to be hooked up to get spark or what and my tci box is good been check help

 

Hi this post is from a while back, but did you get the bike running fine after the loom alterations? Ive done a similar job on my Kawasaki GT550 and it works fine.

by his posts it looks like he was up and running but his post here does not say he had any trouble with the diagram

 

I did it based on this diagram and worked for me

 

Hey buddy, did you start completely over? I have xj700

 

I ended up wiring from scratch. Easier than hacking the original harness.
Just did a complete wiring for a different bike because it is also a good opportunity to replace all pins inside the connectors.
