voltage regulator burnt

[spareparts]

i found their wiring diagram, I don't agree with their color choices, but you appear to have it wired correctly. Make sure you run a dedicated ground wire to the alternator chassis. I don't see where burning up your old regulator would have damaged anything else on your motor. I would check your water pump impeller if you haven't changed it in a while, the regulators are water cooled and a weak impeller can cause them to overheat
