alternator amp is.....

[sid]

91 dodge cummins:what is the amparage on the alternator? where can I get one?--- Where do I go to get the alternator tested?

[TWorline]

Not sure on the amps on the 91 but, a 92 has a 120 amp alternator. Advance Auto and Autozone both do the alternator testing, both also sell new alternators. Get one with a lifetime warranty.

do I need to remove it from the truck to do the testing or do they use that cart/machine they take to the car/truck. will it damage the truck/electronics?

[TWorline]

I am not sure about them checking on the vehicle, they checked mine while it was off.

[RumbleFish]

they can check it either on or off. off the vehicle is more accurate, but on the vehicle is alot more convenient for you. besides, they don't have a 5k dollar mobile Arbst tester for nothing.

[BEARKILLER]

While we're talking checking alternators, can they check them when they don't have pulleys attached ?? ( not on the engine, of course)

I have accumulated several that I would like to know which ones are good ones.

[PToombs]

I don't think so! The tester I saw , you put the alternator on a pin, looped the belt over, hooked up the wires and spun it. No pulley, no spinney?

[sid]

it was the voltage regulator. all is good now

I have not had good luck with parts store rebuilds the last 2 or 3 times I got them. I have gotten my starters and alternators rebuilt by a good local shop, usually for 20-30% less than the parts stores, and I dont have the hassle of my yearly alternator change at Advance, AutoZone, et al. What good is a free exchange if it wont last any longer than the one I took off? I have yet to have to rebuild it when the local yokels do it.
