REFLECTOR: Using the starter supply(+) wire as a charge wire

I talked w/ Skytec starters today.  On their web site they talk about an
alternative wiring scheme that eliminates the normal firewall starter
contactor which is required on certified span cans.  I can wire my starter
button directly to the coil/contactor that is bolted to the Skytec starter
instead doing the conventional route of contactor in the nose that then
ports juice to the Skytec contactor and its starter motor.

 

Terry;

 

I don't know about the Skytec, but typically the solenoid/contactor on the
starter takes a significant current, and has a very large in-rush current.
I think you'd would want a switch rated to 30-40 A; with spike suppression,
for reliability.  I used a automotive 40 A relay for the job (also with a
TVS) so I could use a light duty push button up front.
