Ok, I was little confused by the replies I got, partly because I didn't make it clear what i was trying to do, which is find out what 12 volt parts work in a 6 volt system. Now I'm curious about the coil. Just to clarify, 6 and a 12 volt system both use the same coil but the 12 volt system has a resistor? so basically I can take out a 12 volt coil and put it in a 6 volt system and have no problems because i left the ballast resistor in the 12 volt car? Thanks, and sorry about the confusion.
Yes, you can use the 12 volt coil in your 6 volt system. While they don't use the same coil, when you put the 12 volt coil in a 6 volt system, removing the resistor comes close enough to equalizing things. If you leave the resistor in the circuit, you will have lower voltage to the plugs. I don't recall the numbers from the top of my head, but you won't be too far off when you take out the resistor. Don't be afraid to give it a try, you won't hurt anything as long as you aren't running with a computer.
