Missing Relay

[HelluvaEngineer]

My Voltmeter has been dead since I bought my truck a couple of months back. I know it worked when I test drove it. I took the plate with the relays and starter relay off and one of the relays is missing. I think someone was monkeying with them before I bought the car (it had all kinds of starter issues.)

Oh, my gen 2 light is on too but that may be coincidence.

Anyway, the P/N is Bosch 0 332 204 151 on the one that is still there. Marked 12V 20/30A. Is there another P/N that is preferred?

Also, how do I tell the Gen2 relay from the Voltmeter relay? Are the sockets and relays the same?

I did find this on other threads. Looks like they are two different relays.

Bosch
12v
20/30A
0 332 204 151 (Bosch pn)
12033862 (GM pn)
5 blade terminal connection

Bosch part number 0332204151 interchanges with the NAPA part number

ECH AR272

How about the 10 amp fuse at the bottom of the fuse box?

I think I already checked that but I will again, but the total lack of a relay is an obvious problem.

Checked the pins and they look the same. So same 12v relay for the voltmeter too? Thanks.

Your truck has not been converted to 12 volts, has it?

Nah.

According to this thread, they are the same. I think I'm gonna check Autozone for one here in a minute.

I wasn't asking about the relay.

Well I found the Gen2 problem. The Alternator belt must have broken. I'm trying to find the correct length now. If anyone happens to know it would be a huge help. I'm assuming there's no match on that one for the Blazer equivalent.

Helluvaengineer, by any chance, have you looked at a parts manual for the belt?

For the belt I was able to find the Gates PN (posted above) by searching the site. It's a little quicker than searching the PDFs and then trying to cross reference the old part numbers.

Sorry, I was trying to get some stuff in shape quickly today - Atlanta is in panic mode due to this storm coming through. We're running out of gasoline but plenty of diesel so I was trying to get some things fixed in the CUCV today.

Somehow lost my last reply. The "Nah" was in reference to it still being 24v. The relay didn't work. The fuse is good. I'll follow the technical manual and check the resistor, voltmeter, etc. Thanks.
