Looks like the:
1) ignition switch is connected to the coil positive bolt
2) alternator yellow cable is connected to the coil positive bolt
3) the coil negative bolt is connected to the bolt on the side of the distributor
4) the starter is connected to the Amp Meter.
Do I need to add a Polarity Reverse Switch?
Is there anything I am missing?
The relays confuse me.
