Hi All
while tuning the car today i set the dwell at 30 deg.
the meter was connected to the coi,when i started the car ,it ran for appx. 1 min the tach. started fluxuating and the car died.
Dwell was @ 30.
It would not start again for about 5 mins.
and then started. Again the tach. fluxuated after abt.1 min and the car died.
This happened 4 times.

Did i cause damage to the coil or the points????
I also noticed that the tach would shift as if i had a bad connection.Fuel pressure is ok and at the proper pressure.
I am totally lost and need some help
PLEASE

Bob

That system uses the points as a trigger only, VERY little current flows. As a result the points can get electrically isolated very easy.

I have seen new points out of the box get this way. I have always assumed it to be oil vapors in the packaging. Try moving the distributor till the points are closed and pull a piece of clean dry paper through them (non glossy paper). After the paper grind the points together with your finger or the tip of a screw driver and try again.
