Another thing you can do is use a Ford style solenoid and use it as a relay to trigger the 12ga wire to the GM solenoid on the starter. You should use a relay on a GM starter switch circuit if you use a micro switch for a neutral safety switch. |

Re: Starter solenoid
You guys are making this way to hard. Simply put a jumper wire between the battery post on the starter and the start terminal. Now when the “slave solinoid” is triggered it sends voltage to both terminals! Wow! How simple can you get. No small wire even going to the starter to get burned by the headers. Battery cable going to the starter is only hot when you try to start. Takes very little amperage to trip slave, and the solinoid on the starter is trip by battery voltage and amerage. Win-win situation.

Re: Starter solenoid
And use a Cole-Hersee HD all metal continuous duty rated slave solinoid. The plastic ones can and will stick and your starter stays engaged. None of these solinoid are as well made as they once were. I cut open a few and an old Ford style laying in my toolbox for probably 30-40 years was all copper inside. New ones use cheaper materials. It’s a very good way to keep long run battery cables from being energized all the time. Much safer ....

I have friends at the track who rebuild starters and alternators for a living and they say this shortcut will shorten the life of the starter. When you hit the switch with a jumper in the mix you send the 12 volt signal from the battery that is intended to spin the starter (up to 1000 amps) to the starter solenoid as well. That only requires 12 volts 5 to10 amps to engage the gearing and energize the motor. It will burn out the windings in the solenoid. It's just an electromagnet and a pushrod. A starter mounted solenoid has studs of different sizes for a reason. Wire it like the manufacturer intended and it will last longer.

Kind of. The starter positive post was always hot and shorted against my steering. Here is the simple wiring diagram from an MSD Dynaforce starter. The one I ran the starter positive through a Ford solenoid. A little too simple.
