The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Ignition problems- 305E V6

1. When checking voltage, you just touch the red meter lead to the place/terminal you want to check and touch the black meter lead to good, clean shinny motor metal, body metal or frame metal. You don't add a jumper or touch other posts. If you are testing a component to see if it is bad, there may be different meter hookups.
2. So lets try this again with meter as I described. What is voltage at coil pos with ignition off? What is voltage with ignition on?
3. Someone has tried to wire the ignition from a Chevy diagram or a pre 1964 GMC diagram. GMC changed the ignition wiring scheme a little bit. I just want to check the voltage per note 2 before moving forward with solution. Almost there.
4. Is the coil in the pics the Pertronix Flamethrower? What coil is on the motor now? I don't se any logo on it.
5. Battery is checked with ignition OFF. You said it was 12.6 now 12.2 correct? Recheck with ignition off. The battery is checked across the posts. Red meter on pos post, black meter on neg post.
