Went to check out a '86 NA yesterday, fuel/temp/tach not working. Is this a possible electrical nightmare-ECU?

I could see the sender for the temp, but the tach?

 

digital or analog?

 

Sorry it's analog, I have the digital dash nightmare on my '84.

Fuel gauge I could even live with since it would not be a daily driver.

I would guess sender for temp but the tach and combination of gauges not working scares me-could this thing be an electrical nightmare, not sure if the ECU could be involved. Car is showing 80,000 miles.

Thanks

 

ouch. that's not a good sign. you're probably right. electrical gremlins.
