Before you "just bolt in" a new alternator there is a few things to consider.

1. Your wiring set up right now is for 60 amps.

2. Chances are the wiring has a lot more "load" resistance now then when it was new due to corroded connections, oxidated wire, splices, etc. This additional "load" will drop voltage drawing more current "amps" the the device your trying to operate.

3. Current "amps" across a resistance "load" produces "heat"

4. When installing higher "Amp" alternators ALWAYS up grade the wires to your charging system ans your Fuse box.

5. When installing high amp accessories in an older vehicle (5 amps or more) always use a fuse or circuit braker.

Don't be on the side of the road up in flames.....
