Neutral light issues

PostAuthor: Xeropdx » Sun Apr 01, 2018 11:06 pm

Hello, not exactly sure how these forums work but I have a question that I can’t seem to solve. I have a 1983 xv 750. I have replaced the factory gauges with aftermarket. I have all the wires set up properly I believe and am getting lights from all controls. Intitially when I set everything up the neutral light worked when the bike was in neutral. Now when I click through gears and it hits neutral the light comes on only for a very brief click, and the relays seem to click on and off as well. I’m not getting headlight but I’m getting all other lights. The starter button works just fine when in run and the bike in neutral. I replaced the neutral switch and that didn’t seem to be the issue. Am I missing something? Please help.

Thank you so much!
Sean

remove the neutral switch wire at the switch (dark blue wire). turn the key on then touch the disconnected wire to a solid ground. does the neutral light stay on as long as it is grounded??? ......dan

hello Dan, thank you for the reply!

I seem to have fixed the neutral switch and the light does what its supposed to I think I had the wires to the led on the wrong legs, as soon as I switched it it worked. I'm now having issues getting spark. everything seems to be functioning properly. all the relays are working properly all safety switches are working properly, coils seem to be at the right resistance, I am getting 12v at the TCI I'm getting continuity with side stand switch and relay, I'm even getting a single spark to the plug when I turn the kill switch to on, but when I hit the starter button there is no spark at all. I have fun out of tests to preform. any ideas on whats wrong?

thank you very much!!

Hello Dan, I did have spark before that gauge swap. Just recently in base of the portion of the harness that goes to the headlight bucket I found a severed black wire that has 12v going to it, it’s hot. There was also a mysterious relay inside attached to the horn wires. This is beside the issue but I was curious if you had ever seen anything like that. But yes I did have spark before the swap. I thought I had the corresponding wires connected. The only one that doesn’t seem to have a mate is the yellow and white one that goes to the starter relay. And there was also no mate for the white and green that says speedometer sensor in the manual that goes to the turn signal cancel switch. I also have removed the turn signal cancel switch. All lights, sensors, relays and so on seem to be doing what they are supposed to all lights register to corresponding switch or relay and electricity is going to the plug wire but only for a split second when I flip the kill switch to on.

Thank you so much for your responses, you are giving me hope!

Thank you,
Sean

Hello Dan, a little update on information. Today I bench tested my ignition coils with the battery and plug. I trimmed the plug wires and cleaned connections but the spark was definitely not very impressive and almost non existent. Orange and actually had to turn the lights off to see it. I imagine that this is an issue and could be the culprit of the problem. Yeah?

Thank you!
Sean

our horns do not have a relay. someone added this relay to use a air horn (i assume).
the horns have 4 black wires (2 for each horn). 1 black wire goes to a tan bullet connector. the other black goes to a pink bullet connector.

how did you test the coils with the battery?
you need to run a wire from the battery positive to the coil red/white. run a wire from the battery negative to the coil signal wire (orange or gray) DO NOT CONNECT THIS WIRE. you scrape the negative wire to the signal wire...............dan

I removed the relay and set up the horn as intended and it works, all lights and relays seem to be functioning properly. and that’s how I tested the coils. Exactly like that. 12v to red and white, ground to plug then tap or flick orange to ground. Spark was very weak, I had to turn the lights off to see it. And I had 12.9v at battery.

Thank you again,
Sean

Primary resistance of coils is .001 in the 2k setting on my meter. and secondary is 8.42 in the 20k setting. The reading for pick up coils is .138 on 2k setting on my meter it is this for both sides.

Thank you,
Sean

So does that mean my secondary resistance is way to high yeah?

pickup coils good..
the coils primary are 2.7 to 3.0 ohms.. you say you have .001? wow no wonder you have no spark..............dan
