Re: Alternator voltage regulator installation Posted by JerseySaab [Email] ![]() ![]() In Reply to: Alternator voltage regulator installation, SaabStalker ![]() |
It's pretty likely it's the brush/regulator unit, though of course there may be a fault elsewhere. It's certainly worth checking the wiring on the alternator to make sure nothing has corroded away.
I've done the regulator replacement but it's been a while. On mine I had the opposite problem, the system was putting out 17-18 volts, boiling the battery and causing general havoc in the electrical system.
As I recall there are a couple of screws that hold the regulator in, remove those and it comes out pretty easily while the alternator is still in place. (Of course disconnect the battery first!) It may have been necessary to remove the oil filter or move other stuff out of the way but I don't recall all the details.
To put the new one in can be a little challenging since the new brushes will be longer and under spring tension. I used a thin piece of string or thread tied around the regulator and brushes to hold them in place for installation. Once in place but before tightening the mounting screws, cut the string and pull it out.
It's not a bad job and sure beats having to take the alternator out.
