Fuse box labeling
 

Could some post a pic of a glass fuse fuse block. The writing and ratings are almost impossible to read on mine. I’m making a autocad dwg that I will post for anyone who has this issue in the future

I absolutely do not trust the fuses that are currently in the box as the previous owner didn’t seem to understand wiring, wire gauge, or much of anything mechanical

Thanks

Download the GM wiring diagrams from the RTFM link below.
I believe TOCMP has at least some of the 1970's owner manuals.

Thanks!

I had looked at the 73 wiring diagram, which doesn’t list the fuse amp rating. The 74 does list them.

Looking through the manual for the 87 R10, do you know what that top power window thing is on the fuse block? I have a fuse in the bottom where the power window fuse goes. But there appears to be something for the power windows, if you start at the very top of the fuse block, and go down the the 2nd row of square holes. Seems to be a lot of plugs that go in those holes.

Anyway according to those manuals the 4th hole from the left on the 2nd row, is for some plug relating to power windows. But I can't find what it actually does. Mine is empty, and I'm wondering if I'm missing something.

Does your something for power windows look like this self resetting ATC/ATO circuit breaker?
