Less than 12V on VR Input w/pics

Fittrjoe said
VR input is 11.8 when Batt is 12.56 ,

11.08 vs 12.56 is a 1.5v Voltage drop

Is that with the engine running or off?

That's a lot.

Check...

The bulkhead connectors are clean and tight.

The ignition switch connectors and terminals are clean and tight.

You should check it with the engine running
