"" I run a MSD 6AL and if it will crank, it will fire.""

Since I rewired my CRANK circuit, I am very impressed how quickly the engine will fire with the MSD Street Fire (MSD-5) box. Now, once I turn the key to CRANK, it fires so quickly it is hard to read the voltage output on my digital voltmeter for the CRANK circuit before it starts reading the RUN circuit. It can't be any longer than one second before the engine now fires.

Once I get an official response from MSD tech line, I will update this thread with their minimum CRANK voltage requirements.

Thanks again.
