Question about 1986 Buick Somerset
I have a 1985 Buick Regal Somerset with similar problem. I solved issue by purchasing a high output alternator that would charge battery and power all accesories better. This helped along with changing the size of alternator pulley. If voltage output fall lower than 12 volts the engine may die. This is a major problem with this vehicle. Thanks lou

voltage regulator is internal on that alternator. Take the alernator back off
and take it autozone or advance and have them bench test it to see if its
good or not. That model car doesnt have a fuse for the alternator either and
the regulator is internal on that model. Thats a standard sg gm alternator.
those above stores do not charge for testing it for you. another quick way if
you have a volt meter is black end of volt meter to the negative battery
cable and the postive end of the meter to the thick red wire on the
alternator that you had to put the nut on. then with car running that should
show 13 to 14 volts. If not, suspect that alternator. But try the free check
on it before going through too much more grief with that. if you had it
tested. take the whole car to the autostore and ask them to check it while
the car is running, Autozone and advance both have the machine they will take
out to the car and check it for free. Otherwise, get a volt meter and check
it as I said. If the alternator is putting out, then you have a bad cable or
the 'field' wire is bad.
