Blackwater,

This is a bit different than I was thinking, so bear with me.

I looked at my coil yesterday when I was down where my truck is. There's a wire going to the ignition/distributor and one wire that goes back to the Ammeter.

Don't I want to put the reducer between the coil and distributor? I believe that is the coil out?

I'm not exactly sure what the Ammeter does, it seems to allow voltage to travel both ways depending on the system state, since the coil is getting current from the Ammeter, AFAIK.

The one piece I'm trying to understand is where exactly this voltage reducer goes that I have?
