Just about finished wiring all the instrument panel switches. The magneto switches need wiring and while the P-Lead from the Bendix mag is straight forward, the leads for the P-Mag electronic mag is a little different. In order to wire and get all the functions handled I choose to use a DPDT (on-off-on) switch. The P-mag draws ship's power for normal operations but does have an internal alternator for power in case of electrical failure of the ship's power.
The left side of the switch is for the P-Mag P-lead and the right side is for the electrical power. Down is grounded (L) and unpowered (R), the middle position is ungrounded (L) and unpowered (R) and the top position is ungrounded (L) and powered (R). This allows m to:
1. grounded it when not running is all the way down. 2. normal start and run position is all the way up. 3. middle position disconnects ship's power is the test position for internal power, a runup check.
