I would like to use a start button on the Z-11 diagram with regular
mags but have the option to convert to P-Mags later. Can someone
explain how to or point me to a reference.

Not quite sure what question your asking Ed?

The push button is easy it just takes the +12V wire form the start contactor and grounds it when the button is pushed, thus pulls in the contactor.

A to wiring the mags I would not put in a key swtich to control both mags...I mean if you do that you have a single point of failure controlling both ignitions. Granted it is unlikely to fail because you have to ground the P leads to shut them off, but even so a separate switch to control each P lead is desirable.

The to start you simply turn on both P leads (unground them) and hit the start button.

The nice thing about the P mags is they are wired the same way...I.e have a terminal that connects directly to the P lead you will have already installed.

The only extra things you will need in moved to a P mag from an existing mag is a +12V supply for each Pmag and a good ground (don't rely on the case). Make sure the +12V lines come from a separate circuit...I.e one fuse for each. If you have two batteries or two alternators, one feed should come from the main bus and the other should come from the essntial bus.

Hope that helps

Frank
