TCI, Flasher unit or both?

I was trying to sync my carbs. With the YICS port blocked I had all four gages around 6 inches then my neutral light went out, front brake switch and brake pedal stopped illuminating the back brake. Then the gauges went all over the place. The headlight and hight beam work. No horn, no turn signals. I checked for voltage (per the Haynes manual) at the flasher unit and there is none. Would a bad flasher unit cause all this? There is also continuity at the nuetral switch connection. My tach and speedo light up but my tach does not respond to throttle blips. What is going on here???

Thanks,

Gary

 

Have you checked your fuses? If you still have the OEM fuse block consider replacing it with a new blade type fuse block. The OEM fuses are the cause of many electrical gremlins in any old bike.

 

mlew,

New blade style fuse box checked with multimeter for voltage across. All good. New regulator, new stator, new battery.

Thanks,

This is about to drive me nuts...It's going back and forth. One minute the headlight is on when I start it, then it switches...the headlight doesn't come on and everything else works...flashers, horn and nuetral light.

 

You have a connection problem somewhere. Probably in a main power or ground wire, Check the wires from the battery to the solenoid and ground connections. Check that the engine to frame ground strap is not broken. After that I would start looking into some of the plug connections in the headlight bucket and around voltage regulator.

 

thanks

 

mlew,

Battery is grounded to bike. Earth ground is not broken. Last night I swapped the harness out with a harness I bought from Let It Ride. I also re-wired the fuse box. I charged my battery last night and the non-starting electricals came up...nuetral switch, both flashers, horn, rear brake switch and foot pedal. I don't know yet if the headlight will come up or not because I haven't tried to start it. I need to go over my carbs...it won't idle without the chokes. Hopefully, there was something going on with that other harness that I would have never found.

Thanks for the help,

Gary

 

I looked through a wiring diagram and I would look at the main key switch and the right handlebar switch. The main power goes through them to power those items. Since you have power to some things and not others I would say the main fuse is good, hopefully you got all the fuse box wires back in the right place.

 

mlew,

I, for certain, have the fuse box wired right. Will post pics soon.

1. Main (Red Thick)
2. Headlight (Red w/Yellow stripe)
3. Flashers/Lights (Brown)
4. Ignition (Red w/White stripe)
5. Spare
6. Spare

And....yeah, if this harness swap doesn't do it I will look at the right switch. I re-connected the wiring and may have a bad connection there. I've been using the Haynes schematics to follow the wiring connections. The ignition switch is new and I know that doesn't mean it's operating properly, so, yeah...I'd better check that also.

Thanks,


Gary

 

mlew,

There was a short or open-circuit somewhere in that other harness. I started my bike this afternoon and the headlight and highbeam came on and stayed on. I'm hoping with that not being a problem I can get these carbs synch'd and colortuned.


Thanks,

Gary
