4th alternator 97 pup

this will be the 4th alt. i need in one year. newish battery. belt squeals some in late stages. all Adv. Auto. Their warranty mentions must have battery full charged at beginning. Truck runs fine, until the last breath.

try a smaller belt..

If you are drawing a higher current load than the factory 60 amp alternator can take, you can modify a 240sx 90 amp alternator to work on your truck. You just have to have the pulley changed to work with the V-belt in the pickup trucks.
