Default Re: Is There An Electrician In The House?

The + side of the coil goes to the points and is the ground side. If the points are open, then the + side of the coil should read the same as the - side, with the key off or on, and engine stopped. With the engine running the points will be switching the coil off and on, so the + side should read less than the - side, but more than 0.

The bulk of the voltage readings seem to be high, unless the battery is low or weak, or has a poor connection. What is the voltage reading at the battery posts in the center? Also what is the voltage readings on the battery cable ends? Just searching for a voltage drop to indicate a bad connection.
