[6pack] Intermittent ground?

[John Cyganowski]

Dave-
Glad it worked out.  I was losing those instruments and devices intermittently among other issues.
Once I realized they were all on the same circuit, with some manipulation and they would come back only to go again.  So I replaced the fuse box.  This resolved about 95% of the issues.
Corrosion is maybe too strong a word - but oxidation will certainly occur over time and impact the contacts.
Best of Luck-John

Thanks, John. Your thought process on this is quite good. It turned out that the problem was solved this afternoon, by simply removing the fuse, lightly sanding its metal ends, then reinserting it into the fuse clips! I knew something was quite there when I measured zero volts on one end of the fuse and 12.65 on the other! Prior to that, the heater fan, the turn signals, the wipers, the brake lights and the two gauges didn't work. I re-inserted that fuse and it's like 20,000 volts into Frankenstein's monster. It LIVES! Being as the fuse box is relatively new, as are the fuses, it was hard to imagine (or SEE) any corrosion that could cause such chaos! All from one green circuit fuse! It's been a long tome since everything worked so having everything back at the same time is like having a party with old, long-lost friends! LOL!

Special kudos to IM Sloane for helping me think through this latest 'adventure'....

Thanks for responding,

Dave

driving, they'll suddenly kick on and stay on for the rest of the trip. Some trips, they
don't come on at all. <snip>
David-
Those 2 gauges are on the same power circuit.  Have someone sit in the car while idling, monitoring the gauges.
You push on (I think the top terminals of the fuse box (I think)  See what that does.  If your gauges come up, then I think you need to replace the fuse box (not too expensive or difficult (getting the 2 screws out is the hard part.)
The TR6 fuse boxes were riveted together.  After 40 years of vibration and corrosion, they sometimes fail.
