Would someone please confirm: The starter switch has two posts. One from battery to one of the switch post, then switch battery post to switch starter post then to the starter motor.
Does it matter which post on the starter switch the wire from the starter switch to the coil box battery post goes?
I imagine, once the key is turned from bat to mag, if the wire is on the battery post, then there will be constant electricity to the coils. Do we want this?
I cannot find the appropriate picture diagram for a 1912 re-built with a starter.
The hot wire for the battery terminal on coil box etc goes on the post that connect directly to the battery. The key has nothing to do with the starter switch. The only time that wire would be hot is if the starter switch is depressed if you hooked it up wrong, you would be depressed because the car would only run as long as the starter switch was pressed down. There would be no appropriate photo of that wiring diagram, you would need to use the 1919 to 27 where applicable.
The battery can be connected to either terminal and the cable to the starter on the other terminal. The wire to the coil box goes on the same terminal the battery is connected to.
