Ballast resistor or no ballast resistor

[SMack]

Hey folks I’m sure this was covered at some point so I apologize up front.
On a new build I used a new Mopar electronic ignition system wiring harness and a Rev-N-Nator box , dist. , and coil. Can I bypass the ballast resistor or do I need it. Box is 5 pin by the way.
thanks folks

You still need the ballast you rev n nator box is a 5 pin?

 

[SMack]

Can you elaborate a little John, with no points to protect what else does it do? I’m very electrical ignorant to be painfully honest

It's not there to protect the points... that's the condensers job. It's there to keep the coil from cooking.

If you trust Rick Ehrenberg, the ballast resistor protects the ECU too.

 

[SMack]

Gotcha. Thanks guys as always much appreciated

 

[JohnEngland]

They covered it Pretty good ;)

What are the volts at your coil with ignition turned to on, not running?

If you trust Rick Ehrenberg, the ballast resistor protects the ECU too.

The ballast resistor LIMITS the amps to the coil, which in turn limits the amps the ECU's transistor switches....just MY opinion of course.....

Both 4 pin and 5 pin ECU's
