Part ID help please
Hello gang!
Just bought a nice '75 and started to labor of luv in fixing her up. First thing I noticed was about 30 layers of black electrical tape around the wires coming from the alternator (never a good sign). The main power wire was connected with a household wire nut. But, what has me stumped is what I found spliced in the white wire...see pics.
My assumption is that it is a resistor for the radio but I may be mistaken. Any ideas??

Ok, more research results...learning more about alternators than I knew before. This diode was spliced in the Wire 1: Field Excite/Warning Light Indicator Input wire. Now, I'm wondering if it's even necessary to be there? Can the #1 wire be wired direct without the diode?

From looking at other posts and other sites, the diode is used to prevent feedback and run-on. One post suggested moving the exciter wire to the accessory side of the ignition instead of splicing in a diode. Not really sure how to make that happen so I think I will pick up a 276-1661 diode from Radio Shack today and solder it in then cover everything up with heat shrink.

Spliced in the Radio Shack diode and buttoned it back up. At least I know it's in better condition than when I found it. Next, onto the non-working horn. For some reason, every Corvette that I have ever bought has had a non-functioning horn. Hopefully just a bad ground and not a bad horn.
