<!-- from fixya rte -->Why is 1987 toyota pickup overcharging - 1987 Toyota Pickup

read the VIN Number on the block, see if it matches the VIN number on the dash or door jam.

Need a special speaker, 4" max size, for the front as it has an angle tab to match the molded dash. Try Crutchfield as I bought my replacement Pioneer form them decades ago and it sounds so much better. They provide it with correct plug installed. a 10 minute job.

You need to bypass voltage regulator to be certain alternator is charging properly. When you full field alternator it eliminates voltage regulator. If it indeed is good it will overcharge. If it overcharges as it should when you bypass/full field alternator then the regulator, or its connection or the place it attaches to is rusty & wont conduct a ground.

Id use some Lucas power steering fluid with stop leak and conditioner, works pretty well. If you cant get that than any power steering fluid will be fine
