—Hi guys. I’m having a heck of a time figuring this one out. Slow crank with huge voltage drop of 7-10 volts at positive side of the solenoid.
2 things I found.
Any ideas would be appreciated. Engine was removed painted, engine box painted recently. Ran fine before this restoration done. Tried booster cables to test grounds from block to different places on firewall and around chassis but same issue prevails.

- Remove 7mm coil wire from distributor and ground to manifold. Cranks fine no voltage drop. Put coil wire back on distributor and have voltage drop, slow cranking.
- Remove negative battery cable, positive cable still attached. Volt meter black probe to negative battery post and red probe to any bare metal. Volt meter reads 11.8 volts constant. Open the drivers door and volts now show 12.6. Press the door switch in and volts drop back to 11.8.
