Re: How many volts needed at a starter

This what you are contemplating? Yep.

If you are losing 4 volts at the S terminal then you have a large resistance on the purple wire circuit and it's probably just a matter of time until you lose all your current in the purple wire.
There's some loss in multiple segments (batt to ign, ign to fuse block, fuse block to S post). Factory wiring will be updated at some point. Until then, I prefer that the 8.x volts at the purple wire run a relay rather than running the starter solenoid. Thanks for checking back.
