Voltage Issues

Steve any symptoms here with any accessories or electrical issues? I don't think grounds are a problem unless the ground in question was the one you were using with your voltmeter. Some volktage drop in small wired circuits is normal, but 2 volts is high, I have never investigated, routinely, circuits in the dash or fuse panel like you seem to be doing, I would like to try it on my 98 Lumina. See if you can isolate the circuits that drop to

I would check all of your grounds for starters. Every one you can find in effect areas.

I would check the battery in your meter or try another one. Also what are you using for a ground? Same one for all checks? Check and reseat the connectors and check all grounds.

Also your battery may be bad allowing a lot of electrical noise in the system which will give erratic dc readings....

Here are the circuits that are running at the lower voltage (from the I/P fuse block only):

At time of testing, the "high" voltage was 14VDC and the "low" voltage was about 10.5VDC. The circuits listed above were all at 10.5VDC and the rest were at 14VDC.

Now to see what they have in common.

They all lead me to the left side under hood electrical panel. What I found when I got there was a rather large voltage drop between the remote battery stud and the fuses. I disassembled the stud, cleaned it all up with LPS contact cleaner, put it back together and coated the whole thing with dielectric grease. All seems to be back to normal.
