What type of starter switch did GM use for the 4106?

I see that it must be a DPDT by looking at the schematics (Six spades on the bottom) and had one momentary position. My question is was it a two position or three? I'm trying to fix things the right way.

Example:

Three position with one position momentary: (on)-off-on

Two position, one momentary: (on)-off

Thanks,

Laryn

Two position, spring return, if ours is original. The wiring changed quite a bit between the early and the late ones, the late ones using a simpler circuit.

Hi Laryn,

Are you talking about the starter switch next to the driver's seat, or the one in the engine compartment (rear-run)?

If it's the one next to the driver's seat, it's a spring loaded, two position: normally off, momentary on: off-(on).

If it's the one in the engine compartment, it's a three position switch: normally on, normally off, momentary on: on-off-(on) with the momentary in the bottom position. From top to bottom, this switch will be: "On" for normal (front) starting, "Off" to isolate the starting ciruit, then "Momentary On" to engage the starter. This rear-run control switch should be six-prong.

Good luck! - Steve
