Hello, I recently changed my points system to electronic. I disconnected some wires from my coil and did'nt write them down. I have a wire going to my starter, and two wires to the fuse block via the firewall, one of which is aluminum, that i was tracing in order to replace with copper to get the correct voltage to the coil. I can't remember which wire goes where.I beleive the wire i'm replacing goes to the positive side of the coil but can't remember where the other two go. I know it sounds stupid and i shoud have wrote them down, but like many , i had a few beers while working on my car, enough said. Any help would be very helpful. Thanks Denis

The yellow ( starter ) and the white clothlike ( resistor ) go to the positive side. The black wire ( from distributor ) goes to negative . Now, if you have a 2nd wire coming from distributor ( because of elec conversion you just did ) , it will probably go to a full 12 volt ( use ignition on fuse box ) ... The resistor wire does not carry 12 volts ( 7 to 9 volts instead ) . Check/Read your instruction to be sure on + feed wire for electronic conversion ...

That cloth wire (resistor wire) can be though of as a ballast resistor if your particular ignition instructions show one. But as sdt^2 said, electronic ignitions usually use a full 12 volts with no ballast resistor or resistor wire. But there are some that use both - a full 12 volts to the module and a ballast resistor or resistor wire to the coil.

Thanks for the reply. Other than the cloth covered wire going to the fuse block , their is a brown wire. I'm pretty sure the cloth covered wire goes to the positive side but not sure about the brown wire. Denis

Does the car have a factory tach? If it does, the brown wire went to the negative side of the coil.

Can I take the red wire from the new ignition module and splice it with the cloth wire and bypass the coil? I think they ran them both to the pos. side of the coil just for a termination point because the wires don't reach? Denis

You need to refer to your instructions to see if the module requires a full 12 volts. What brand is the module/kit you installed? If you require a full 12 volts, your car may run erratic if the voltage is too low, so don't use the resistor ... If you require a resistor to step down the voltage, you can to run the red wire to the + side of the coil by extending the red wire by splicing in an extension ... Because the cloth wire is "unique", I would be inclined to leave it intact ... just my personal preference ...

It does require 12v thats why I'm changing the cloth covered wire. I was told that this wire was aluminum and and transfered 9v to the coil on a 12v system so the points wouldn't burn up.

Just run the red wire to the terminal marked IGNition on the fuse block...
