1988 Toyota 4Runner mileage: 155,000 My 4 runner seems to be overcharging. I replaced the alternator with a new one and it seems to be overcharging and getting hot. Does this particular alternator have a built in regulator or is there a separate external regulator like the old Fords. I would greatly appreciate any info you can give me.

Your 4Runner has an IVR (internal voltage regulator).
