4 Speed Starter Solenoid Ground

[Wolfe440]

1969 Charger 4 speed.

The firewall starter solenoid has a ground pin, for automatic cars a brown wire connects to it from the automatic neutral switch.

But on a four speed there is no ground feed to the solenoid, so what source delivers the ground to the solenoid?
None of my schematics give any indication.

Thx,

i believe if you don't have the clutch switch (may be 70?) this goes to ground. I think there may be a difference version that is case grounded instead of external for the stick cars.

for instance, the rockauto ones from Standard shows the SR105 has a seperate blade terminal for ground, and the SR106 its soldered to the case

How interesting, very good. I have seen many but never saw one that was grounded to the case. I been looking at four speed car pics online but never clear enough to see the solution, and I don't know what happened to the original solenoid.   

Thank You!!

In 1974 there was a switch activated by pressing in the clutch which fed the ground to the start relay.  Seems to me that having it any other way would be fairly dangerous.

Right! I been thinking the same thing. 

I drove a 69 4 speed Bee in the 80's, and a 69 manual RR and have no events to remember. I think the factory starter didn't do much with car in gear, and I used the emergency brake a lot being a manual. But not sure with today's higher torque starters....of which I am using one now. I may have to do a test.     

Fix would be to rig a brake switch to the clutch pedal, simple ground circuit.

In 70 4 speeds began to get same relays than autos, getting the ground from as mentioned, a clutch switch with a green wire throught the firewall. This switch is really weird per I have seen, somethimg like a rotation system switch?. I think could be used some other kind of switch, like the one used on emergency brake switch somehow mounted into the pedal assembly with a bracket? Sorry, I'm not familiar with 4 manual cars.

Otherwise just use the correct relay or jump out the ground prong from autos.
