Need a GURU! Electrical issue during carb sync!!!!

[Flyinfool]

The odds of all of those bulbs burning out at the same time is so slim.......

 

I would be looking for a bad wire connection to the dash. Most likely the ground wire.

 

When there are multiple issues in different systems that all happen at once it is almost always the ground.

Ya, there has to be a common factor with it. I've pulled the bulbs and they all look good. I've taken the connectors apart and cleaned them. The Neutral light works and ALL other dash lights work. It's the lights that are controlled by the left hand switch that are the problem. Is there anything in the switch that could be a factor? Going to work on it after lunch.

yep. multi electric problems usually mean a bad ground or blown fuse.

Fuses are all good. Are there any in line fuses that could be a problem?

There is a thread for taking Left hand controls apart and cleaning. And there is one for the right hand controls. Neither are 5 min jobs.

Thanks, Got it!!

I had a bunch of bulbs go out close together. Replaced them and things worked again. Also, If your console is shaking/vibrating, I put a thin washer on the bolts ( mine were shoulder bolts) and that helped tighten up the console. I used a ratchet type box end to loosen and tighten those bolts... made it a whole lot easier.

Don't try to overtighten shoulder bolts. It will get you in trouble!!

Got the signal lights working again. Hazard switch was disconnected!!!!

But the headlight indicator and high beam indicator lights still do not work. I think the Reserve light unit is faulty. When I was testing for voltage on the dash bulb sockets I got a 11 volt voltage reading on the head lamp indicator socket. but under a volt on the high beam socket. When I put the bulb back in it cam on. when I flipped the switch from went out and would not come back on when I went back to high beam. Now the odd thing is the indicator light is acting like it is the hi low light indicator light. When I go from low to high it comes on and when I go back to low it goes out! Now here is the reason why I think the Reserve Lighting Unit is messed up. I gave the unit a LIGHT tap and now all I get is a very dim light from the Head light indicator light. Not even enough to be seen when the light is put back in to the case. So what do you guys think replace the RLU?

I seem to remember someone mentioning that when they changed the Headlight indicator to a LED that the LED was always on. Like there is some leakage out that wire, enough to measure or light an LED but not enough to see when the bulb is installed.

 

On the other hand you might have a faulty RLU. I think I still have the RLU that I took out of my '88 to install the HID headlight. I assume it was working when I took it out. I never burned out a headlight to know for sure. If you want to try it, let me know. Then I just have to find it.........

Sure would like to give it a try if you don't mind. At least then I'll know if I need to replace it thanks.
