OK...I checked under the hood before removing the alternator. My fan belt was twisted and off the pulleys. Turns out that when the belt goes the Brake light and Battery light come on. Nice to know. Maybe I tightened it too much. Take off to test the car and show my mechanic the new battery monitor. Come home and as I'm coming down a hill the brake and battery light come on. Now I know what's up. Go up another hill to my house. I park the car and it won't shut off so I have to use the emergency off switch under the hood. She was boiling over too. I had no interruption of voltage (At speed mostly 13.5 to 13.8 or so)except at idle and it appears I have another problem...Could my water pump be throwing the belt off? Do I need a new belt? Do I need a new water pump? Oh well the pleasures of owning a vintage car. Any advice welcome. Lawrence Rhodes

My alternator has 285k on it. Just what does Bosch do when re manufacturing the alternator. New bearings I bet and the brush/regulator. The commutator is the only other thing. Can the commutator go bad? How often do they go bad? My alternator was soaked with hydraulic fluid. That can't be good. LR

No charging. Battery light & brake light on when driving. I guess I'll take the alternator out and have it tested. How many ways can an alternator fail if it has a new regulator/brush combo? Voting against the wires and for the alternator being bad. Lawrence Rhodes
