Yes, the primary wire from the distributor is attached to the negative post on the coil. Why? Other than that is what the manual says? I'm a mechanical engineer. We need an electrical expert for the why. Hoyt | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | Because you have a negative ground system. The points ground the coil then open again causing the coil to fire. | | | | | Joined: Sep 2008 Posts: 226 Shop Shark | | Shop Shark Joined: Sep 2008 Posts: 226 | it also, has to do the way the "COIL" is made internally. the windings only go one way or the other depending on if your are a positive or neg. grounded system. all our trucks are Neg. ground at this point.
