Ignition Issue, motor wont stay running

VERY SIMPLE

DID IT EVER RUN or have you recently made modifications?

Find a way to bypass the ballast resistor if it is still there.

If you ELIMINATED the ballast, the old ballast connections MUST BE JUMPERED to get it to run

Clip your meter to the coil + and ground
Turn key to run. You should see somewhere around 6--10V but not much higher.

If not, get under the column, access the column wiring connector and check the "run" IGN1 wire at the ignition switch connector.

Could be something bad in the ignition switch, switch connector, bulkhead connector, any of the wire terminals along the way, or the BALLAST resistor itself

The path for the "run" wire is from ignition switch, through the bulkhead connector, and to the ballast resistor. A splice there nearby also powers the VR and depending on the year, a couple other underhood loads

Be cautious, THAT IS NOT FUSED
