Thread: Another Pontiac for the firebird

My electronic flasher circuit controls brake lights also, so I'll have it hot. The alternator is a three wire. I think I've seen the article, thanks for linking it.

All the schematics I've looked at show the field winding (sense lead) hot, along with the indicator lamp, but I don't see the harm in putting them on the acc. Circuit.

I've got everything coming through the firewall landed on terminal strips, so next I'll be wiring in relays. I'm definitely thinking to put a relay between the start solenoid and the switch. Should make the ignition switch last indefinitely.

Seems to me that the starter solenoid IS the relay to protect the ignition switch, and adding a relay in the circuit is an unnecessary complication and an added failure point with little value. Just my $0.02

The flasher.. which one? 4 way "emergency" or the turn signals ? No matter, the brake light switch feeds the turn signal switch... so there is no control from the flasher. The accessory circuit will only be "live" when the key is turned into that position.... think that one through in regards to alternator! adding a relay to control a relay?? why?
