Failed alternator and failed tuner

[Mopar1973Man]

I got a job that a 2001 Dodge was having lock up issues typically. Now the owner had the BD noise filter, the APPS wiring mod and ground mods. Still in all the truck ran with a surge and dropping of power. The old alternator I measured at 0.1 to nearly 0.2 volts AC. He replaced the alternator I measured today and its right about 0.04 to 0.05 marginal. Still the loss of power and surging. The owner has a Bank's tuner on so I opted to removing the MAP leads and return to stock and the Wire Tap. Went for a test drive and the problem is gone. Moral of this post is alternator noise can do damage to even 3rd party device like tuners.

What alternator brand would you recommend getting? I feel like the off-the-shelf rebuilt ones from Orileys probably aren't worth a great deal in quality.

Honeslty just one with a good warranty,  Test it when you install it and go from there.  

 

 

If you have a good alternator shop local go talk with them.
