I have a Military truck with 2 Alternators & one went bad so I initially had a nightmare with trying to find the right replacement. Needless to say, the new one stopped working properly 2 weeks after I purchased it. I luckily found the gem of place and he took one look at it figured out what the issue was & replaced a crappy core component with a much better replacement part and it's now working perfectly. I highly recommend this place and you'd be much better off not buying a new one but having him rebuild one for you. This way you'll have a better Alternator for less money!
