I have been trouble shooting a loud squealing sound that looks to be originating from the alternator. I have been calling around getting prices on alternators and they are all over the map. Advance has a couple ($35 World Wide brand, $29 remanufactured, and a $125 Beck/Arnley). Cummins had one (have to order) for $186. Napa had the Wilson for $209 (heavy duty line according to them).
I want to zero in on the problem, but don't want to buy a $200 alternator and find out it wasn't the root cause. Should I just buy the cheap one and see if it's the problem?
