Pre-Rotation Circuit Breaker problems.
I just tried hand propping the rotor blades and pulsing the solenoid switch, I called it quits the second time I popped a 300A circuit breaker between the battery and the solenoid.
My current circuit is, positive battery to 300A breaker to HD solenoid to mast starter. Starter negative to battery negative. Solenoid on two cab panel switches in series.
I see a soft start diagram on this Forum. It looks like that individual ran a completely separate medium voltage line from the starter into the cab through a switch and then a non breaker-ed line thru the firewall to the solenoid. Then across the solenoid terminals he has a resistor wire.
I'm not an electrical guy, but ... If you only added a switch on the original hot lead to the starter and that switch was in the cab, then put a resistor wire across the main solenoid leads, You could switch the main hot lead in the cab and run the starter across the resistor wire on the solenoid, than switch on the solenoid and run higher amperage thru the solenoid straight from the battery???
I really don't want to put a high amperage switch and reroute parts of the hot lead in the cab on its way to the starter.
Is there another option?
If not, OK. What type of wire, gauge, material, length and it will need to be insulated, it's in on the fire wall.
