Looks to be a crappy two pole....crud.

This looks like the one I have....

No matter how you fry it...pun intended???.....this is a place where you don't want re-engineer the wheel and gat fancy about it.

First, the switches are notorious peices o' crap. Get a good one because:
The last thing you want is an internal issue or a connection issue frying the alternator, or wiring etc, and the next to last thing you want is the thing to suddenly go down on you with the "2 to go" signal on grid.

Smart Racing has the best solution, and you can move on to other more important issues

How about Flaming River....they are the ones sold at Summit Racing.

I got mine from TRE, of this board..

It came with the alt resistor, (which you dont need if you wire up an ignition cutoff as i mentioned earlier.)

Well, I agree that if you cut the ign only the car won't run for long, but the alt is live as the engine spins down and I'm not sure the diodes like that, which is why the six pole switches both cut ign and provide alt with a load. Particularly big deal on a 914-6 where a fried alt means an engine drop on top of the alt expense.

I have a question.
If you do the connections like the Smart Racing diagram, will you have always a current flowing if the Switch is left in the off position?

Just ordered from TRE....

Uhm it wont run at all. Its instant.
I do understand the arguement of the Alt, but thats because most people dont wire in an ign relay cutoff. Pull switch and car cuts off instantly. No coil output., no run. Its doing the same thing as if you turn off the ignition key.

FWIW, apparently the factory knew how to do it with a 2-pole.

Its sort of the same thing as if you turn off the ign, but if you turn off the ign the alt still "sees" the bat as it spins down, 'cause its on the same terminal as the battery main-I understand that we're splitting hairs, but better safe than sorry.

The two pole works if you isolate the alt from the ign by running the feed seperate. John raises a good point about a long unfused run of wire, so I'd put a resetable 40 amp breaker or something inline close to the alt.
