Electrical Issues?

[Seeker]

Yes I have tested it and it tests bad. But when i take out the alternator to warranty it passes the bench test. That's why I am leaning towards a wiring issue. But I am going to switch my wife's alternator with mine first

Did you take it to more than one shop for load testing? If you have a dedicated alternator rebuild shop where you live, may want to take it there for testing rather than the average parts house guy.

Drop the alternaator on the ground and snap a mounting ear off. Take it back to Pepboys and have it replaced. Their bench tests do not put a load on them and only check output voltage. It is failing under a load. More than likely the internal regulator is bad. I have had to do ths with a RetardZone alternator.

Quick easy way to check and see it if is putting out under a load is remove the positive terminal from the battery when it is running. It should stay running if the alternator is any good.

I'll try that today before switching with my wife's. Do I need to pull or can the alternator shop test it on?

At the alternator shop now. Did the pull the positive battery cable test and it shut off. (Though the shop guy said I should never do that. )

They said they want me to remove it first....

most alt shops want it removed so they can bench test it and give it a proper load test

Alternator shop said the brushes on the alternator are bad. Going to go get it warrantied. They said it's common on Chrysler alternators to fool the auto store test. Ace alternators in Santa Fe springs took good care of me with no charge!

good to hear you got a REAL answer, rather than the parts house monkey default reply of 'duh, the machine says its good'
