My 68 is acting up again, and I am suspecting excessive voltage. I was getting 14.7-14.8 V at around 1500 rpm yesterday. Later, I was at 14.4. Power windows etc seemed to move faster than usual. I think this may be excessive, and may be frying the points. Any knowledge of what the maximum voltage should be? I thought around 14V is about right.

Thanks

Over 15.0 volts and your in trouble...
Check Grounds...
The regulator might be no good.

Thanks. I had replaced the regulator recently for the same reason, excessive voltage, frying points. Unfortunately, the diagnosis was not easy, and I got stranded at least once. Now, it may be happening again.

But you are suggesting that 15.0 volts is the trouble, 14.8 is ... OK?

At 14.8... That would be a crap shoot.... Trust your meter or call it defective.. Me.. I would call it defective and get a new regulator. Make sure the grounds throughout the car are all in good shape.


As for the point Burn issue.... That to me would lead me back to a ballast resistor problem or just plan cheaply manufactured parts maybe.


Just my point of view,,,

Check the voltage on each side of the ballast resistor. I think ideal voltage on the coil side of the resistor is around 9 volts. When you change your points, be sure to change the condenser too.
