Engine test stand wiring??
So let's add what needs to change:
The UPPER arrow is where you will take off for the "run" connections. If you want to add an alternator, this is where you will tap off the blue field power and the VR IGN power. This is also where you tap off for the Mopar ECU "run" voltage which will hook to the upper diagram at bottom left the BLUE wire
This upper arrow is where you connect electric gauges and any other component that needs to be switched off/ on with ignition
The black arrow at middle right off the start button is the beginning of your bypass circuit. YOU CAN NOT simply hook that to the yellow "start" connection in the upper diagram. You either need a big diode in series, a second push button, or a second relay.
the OTHER thing you could do is run down a later "Jeep" style relay. This would replace the "starter solenoid" in your diagram AND provide your bypass contact
NOTICE this later style relay has AN EXTRA contact/ terminal
The way to wire this:
1...Big stud goes to battery HOT
2...Terminal marked "fuel pump ballast" goes to the yellow wire in the Mopar ignition diagram above
3....Terminal marked "solenoid" goes to your Mopar starter solenoid
3....Ground the terminal at bottom marked ground
4....Run the bottom left terminal off to your starter switch
The real problem is, that there are many ways to skin this cat!!!! As Crackedback might say!!!
