Ignition switch and distrubutor basics...

Now that I've made progress on my alternator issue...I'm moving on to the other wiring and wondering if I have that right.

Issue #1 Ignition switch (attached picture)

I have a center lug which goes to a starter button (because the switch was sticking and I didn't want to burn up my starter). A terminal labeled BAT which has a hot wire directly from the fuse block. A terminal that is IGN, I assume this is hot when the ignition is on and has a wire that runs to the coil and a wire that powers my gauges. A terminal that is ACC, I assume is hot when the key is rotated counter clockwise to the accessory side that I have the exciter wire from the alternator hooked up.

Questions...is that right? I think the exciter wire should be hooked up to the IGN terminal. Also, should the ACC terminal have power only when the key is in the acc position, or should it also have power when the key is in the ign on position?

Issue #2 Coil wiring (attached picture)

I have a wire running from the IGN terminal on the ignition to one side of the resistor. On the other terminal of the resistor I have two wires, one that goes directly to the positive terminal on the coil and the other goes to the small terminal on the starter (not the "S" side, I think its an "L").

Question...is that right? I don't want to burn up the points!

Thanks!

#1 seems correct.
The ACC should be hot in IGN position.
Don't forget the resistor in series with the excite wire to the alternator.

#2 seems correct.
You should mount the resistor away from the plug wires. Resistors get very hot.

Thanks Vic.

I've got the resistor between the alternator and the ignition switch...learned that the hard way. I had to pull the coil wire to get the truck to shut off becasue the alternator was back feeding the switch. Oops.

Is it ok that I have the excite wire on the ACC terminal on the switch? Sounds like I need a new switch, b/c the ACC side isn't hot when IGN is on...I didn't think that was how it was supposed to be.

I'll mount the coil resistor on the fire wall, thanks for the advice.

Yes, just connect the excite wire to IGN.
