An earlier classified for an ACS keyed ignition switch got me thinking. That item becomes available when people convert to a push button start setup, so I thought, why don't I look into that. So I came up with the simple approach in my head and then I thought about extensions to that. No idea if I'd actually do this, but here goes.
I have a VP-X Sport which has a starter output that currently goes into the ignition switch (BATT). This voltage is passed to the S post (on switch and starter contactor) when the key is in the start position. The VP-X will turn this circuit off if it sees that the engine is running. So..
L and R mag toggle switches (upside down so 'ON' grounds the magnetos)
Starter circuit from VP-X goes to hidden enable switch then to an illuminated push button that is wired to always be on (based on this starter circuit). This would illuminate the button when the master is on and the engine is not running. Simple, right?
Now comes the idea. If I wanted the button to only light up when one of the mag switches was 'On' (which is actually off), how would I do that? This would essentially act as a hot mag light when the master is on. Make sense? It would be easy if the mag toggles weren't upside down, use DPST toggles and wire the starter circuit in parallel across one pole on both toggles. Doesn't work in this case.
I know, simple is better, but I think this would be a great feature if it could be done without adding too much complexity. And yes, I'm aware that this wouldn't warn me about a hot mag if my master is off. It's still going to be inferior to the removed key protection that you get with the keyed ignition switch.
EDIT: Would a DPDT On-On switch work? The schematic I just looked at connects pin 2 and 5 to pins 3 and 6 respectively when toggle is down and to 1 and 4 respectively when the toggle is up. So connect p-lead to 2, ground to 1 and starter circuit to 5 and connection to push button to 4. I think that does it. Thoughts?
