serpentine setup

Make sure you have the correct rotation water pump for your setup

but if you don't have money for a new compressor you can get the bypass pulley.

The money isn't so much the issue, as being disabled out in the bush. Out here the woods will kill you if you're not prepared, and cell service is rarely an option.
Carrying a back-up belt doesn't do you any good if you have a component seized up.

I'm not sure what a bypass pulley is. I'll have to look that up.

Perhaps I sound overly paranoid, but I like to learn from others mistakes, and I don't ever want to be "that guy" that had to be rescued.... and I want a supercharger...

I assure you serpentine setups are not as unreliable as you might think. They are very reliable, that's why most modern vehicles from 85 or so and up all use them.

A bypass pulley is just a bracket that mounts where the missing component would go with a bearing and pulley on it. The pulley is the same as what would be on the missing component. A new compressor for my truck is about 250 bucks, to bypass pulley is 30 bucks.

What about the factory alternator if it had the one big 10mm wire and a two wire plug just in case others might have the same question but different factory alt. How do you wire the same serpentine alt. With the plug with one wire into the system if you have the factory alt with the two wire flat plug??? Thanks in advance and I'm pretty sure this will help someone out. Just a thought!!!

My truck had the alternator with a 2 terminal spade type connector and the charge back wire at the back. You can get a plug from a dealer or I think auto parts stores for the serpentine alt. Then I just used the wiring diagrams for both types of trucks and cut the old plug off and wire the new one in matching the wires to their position. Obviously  the charge back wire at the stud on the back goes at the same place on both alternators.

It's been so long since I did that lol, you made me have to think how I did it. I think that's right.

Glad you remembered I was a thought that came to mind and pretty sure your answer will help someone

I'm glad I remembered too. At first I thought uh oh! But it started to come back to me. If I think of anything different I'll let ya know.

The adapter falls under MANY MANY different part names. I just put a CS140 into my truck and had to buy the adapter myself.

Adapters:
Non-resistor adapters:
- AC Delco: 8077
- NAPA: ECHEC80

Resistor adapters:
- AC Delco: 8078
- NAPA: ECHEC82

I then wired in a new 8g feed wire from alternator to the battery.
