1974 Dart 318 crank, but no start (Solved)
This is also cheap and handy device
It will show when there is spark while leaving your hands free.
Current and voltage.
Voltage is the level of energy. Current is the amount of electrons moving.
Current can branch off.
Resistance causes current to lose voltage.
Here's a simple diagram of the factory points system begining to start.
Orange arrows represent current flow.
When the starter motor spins, that pulls so much energy the battery voltage drops, but ignition start path remains the same.
Only difference for your set up is the ECU needs to draw power.
