alternator issue
Im haveing a problem with my alternator. the auto parts store told me that it was bad so i bought a new one. now that i have the new one in they are still telling me that it is bad. I think it might be a short some where becaue it is only putting out 30 amps instead of 90. If anyone knows what might be wrong or has had this problem advice is much appriciated.

I wouldn't be surprised if the new one is bad either. It happens quite frequently with alternators actually..............
What VOLTAGE is it reading at the battery with a voltmeter? (and also on your voltage gauge on the dash) Should be in the 13.5 - 14.0 range if the charging system and battery are working properly

In order to generate 90A, you're going to have to make sure you're drawing 90A - either with a dummy load or actual electric loading from vehicle systems.

the 30a is a number i got from the auto parts place when they tested it when it was n the jeep. i also got it tested off the jeep and it put out 90a so i think that it might be the feild regulator
