dont feel bad stephen, cat has had similar issues with its alternators on the P and C model trucks. Our promatch ones are like playing russian roulette, theres a 50/50 chance the one you get will work. And even when we take them to the rebuild/repair shop they have to use OEM voltage regulators in them, if they use the aftermarket VR's they dont work.
glad you figured it out though ;o)
