[quote=amigo-2k]Your problem is probably with the alt. Isuzu's don't like aftermarket alts.
hunt ebay or
www.car-parts.com for a used one or an orgianal one that was rebuilt.[/Q
Thanks... I searched car-parts.com and found a used alternator ($40 buck) plus $75.00 in labor to get it put on over the weekend. The flickering is gone for good I hope

. Took the old one back to Oreilly's for a refund totaling $115.00. So i broke even there, I also am waiting to hear back form the district manager regarding my labor charge, he reimburst me the last time I took the first one that they sold me off. I spoke with the office manager this morning he said the alt. tested good so he could not approve the labor charge, but he will talk with the district manager when he stops by today. I told him that it may be testing good, but it's not good my truck. The voltage on my truck was eating that alt. alive....
PS. This site has been so helpful. When I experience small issues with my truck I come here first....Your solutions have been 100% right everytime.
