    High output alternator swap?

    I was driving with my new fans and my alternator went out im pretty sure. Because my new electric fan was pullin too much juice. So I was told that there is an alternator swap I can do to my truck (86 Jimmy w/ 350,) to put on an early model alternator from a car or something. If anyone has info on this let me know. Or how to get a bigger alternator while cutting costs, again Im thinkin junkyard.

    You can not just use the 140 amp. It mounts different and you don't have the computer to control it. A 90 amp alternator should be enough and I think that's as big as the normal delcos got, maybe 96 amps. Other than that you can choose from a whole ****load of aftermarket high amp alternators or high amp conversion kits.

    Search for cs144. I have beaten this topic to death. Its cheap but will be a PITa to mount in your situation. After you search if you have any specific questions let me know.

    I've been running a 90amp and before that I was running whatever toyoda was using in 1969 and it handled it fine. I doubt a ford taraus came with a 200amp alt

    An 86 was carb'd and only had a ~70 amp alternator so yes with the fans upgrading is a neccesity. Before I made the swap on my truck with my factory 70 amp alternator the fans would drain the batteries even with the engine running.
