Alternator Replacement Advice

    Hi all, my alternator died last week - the positive lead rusted off and I think a diode fried from the resulting overvoltage.

    Battery died, car wouldn't start, and once the battery was charged enough to start the engine the battery light flickers and I measure 28V AC across the battery terminals. Sounds like a diode, no?

    Anyhow, my options for replacing it are

    $120 - RockAuto cheapest alternator ( EXCEL AUTOMOTIVE Part # 10162 ) remanufactured, shipping included.

    $140 - Local shop that claims they can rebuild it for this much.

    $190 - Canadian Tire - major distributor, remanufactured .

    $300 - Local shop that claims they have a brand new OEM alternator, and warns to watch out for shittily rebuilt alternators.

    Any advice on which to pick? Do remanufacturers / rebuilders do a decent job with fried electronics? If the alternator over-volted enough to burn a diode, is it likely that the rest of the alternator electronics are damaged and might fail later?

    Myself i think id go with your cheapest option most electronics have a no warranty clause once its used on a vehicle unless the failure is immediate.Myself id chose option A and hope the alternator is only electrical problem.
