Minimal wiring troubles XJ650

I have wired up the minimal wiring using the diagram located on the forums i have a black with a white line left that doesnt seem to go anywhere. Im working with no relays can't seem to get spark. Does anyone have a minimized wire harness they would like to sell ?

Hi, Vulcan 750
I saw this in an earlier post from Chacal

"black wire with a white tracer stripe indicates the use of the kickstand switch relay lead wire"

Could this be your kickstand switch wire ?

 

Vulcan,

If you followed this diagram to a T then the wire coming from the kickstand would not be an issue.

This diagram is intended for making your own harness and alot of loose ends could be left from trying to modifying your original harness to match it.

I run this diagram and it is correct, I would retrace your steps

 

Its a wire left on the plug going to the Ignitor Module. Should i ground it ? I did not include any of the lights or blinkers its just ignition. The kickstand switch if i recal on the oem wiring coming from the switch was white and then turns black with blue tracer. I am doing some searching on the actual pinouts of each of the modules. I tried hooking a meter to it got nothing + lead on the black/white wire and - lead to the chassis. Yeah im trying to wrap off all the loose ends so if i break down i don't have as many worries.

 

If my memory serves me there are 2 wires on the ignition module that aren't hooked to anything, you cannot wire an auto key and have it work, the start function on the key will not spark the plugs for some reason.

 

Ok i wired the starter solenoid with a radio shack momentary push button coming from the positive side of the battery thru the switch to the solenoid and the other side of the circuit is grounded. so the solenoid is directly connected to the battery. I see on the rectifier regulator there are wires O(orange) White W W - coming from the altenator. and also Ground(solid black) R(red) and br(brown). I did away with the lighting so that it would be a wee bit easier to get it actually running on the current configuration. adding the lighting is not to big of a issue now. The RED highlights in the pictures are the wires in question > im on a 1981 650 maxim. I havent ran across a orange wire coming from the altenator i do see a green and red wire though. Still no spark though.

 

Hi, vulcan750

I just did a quick check on my bike and you should leave the black/white striped wire disconnected.
On my bike there is a separate factory butt connector close to the 6 pin TCI plug I can unplug if the kick stand switch is not opening correctly.

With the black/white stripe wire disconnected, I can go in gear with the kickstand down and the bike will not shut off.
With the black/white wire connected the kick stand must be up.
You are not using the kick stand switch, so tape this wire off and leave this wire disconnected at the plug.
If I check the 4 pin TDI plug with the ignition on but the bike not running
and the 4 pin plug disconnected I get + 12V to ground on the orange, grey and red/white wires at the back of the 4 pin connector.
The black wire is ground.
Do you have 12 V on the red/white wire? If you have 12 V on the orange and the grey wires as well, the coil primary windings are connected OK, too.

When you power the TCI on and then switch it off, you should get a spark.
Take a plug out and ground it and switch the ignition on and then off, any spark?

I hope this helps!
By the way, thanks for getting me to check this out, I found my missing gas tank retainer clip in behind the TCI mounting plate

 

Brown is a factory power feed. Basically in the picture you have the red going into rec hot always and the brown is hot only when the key is on, as far as the whites it is a factory plug that doesn't need to be changed. And ya basically the wires from/to the batt/ solenoid are connected. Here's my exact wiring diagram all you need.

 

im not getting voltage to the coils. yet im going to just pickup a new TCI and Regulator. See if that works. I taped off the black and white wire. Ok streetbrawler 750. So there is only 3 wires coming off the REC REG that are used aside from the alternator wires. If the altenator was out the bike should still fire off the juice on the battery though right until the battery goes dead ? The voltage on the white wires is going to be AC correct not DC.


I will have to check to see if that red/white wires hot tomorrow and get back with ya.

Im diggin the hand drawn schematic thats very plain and simple for folks to understand.

 

Ya those 3 wires make it work, one is a ground. I would think that it should run, just not charge if the alt is bad. Don't know for sure.

I had to draw it out for myself to understand, it really works to sit and draw it out and figure what goes where first on paper then start with the hands on.

 

ok im getting voltage to the red/white striped wire. 12v. but i didn't get anything of the grey or orange wire. could the Ignition module be out ? thats what its seems like.

 

The Red/White wire also connects to one side of each coil and then passes through the coil primary and there should be 12 V measured on the orange wire and the gray wire where they are attached to the other side of the coil primary.
It sounds like you don't have your coils connected to the red/white wire 12 Volts.
See both drawings: the red/white 12 V connects to one side of each coil.

It sounds like you are almost there!
Good luck!

 

i checked the voltage on the gray and orange both read 12v i think its something in the rotor possibly

 

just posting to let everyone know that i got the problem fixed it seems that it was the ignition module after all.
