mustang down!!!
bonnevista:
It sounds like a Bosch GT40R. The 'R' means it's designed to use with a restistor, ie, reduced voltage. The idea of putting 'resistance' in the wire going to the + side of the coil is to reduce the voltage. By doing this, it prolongs the life of the points. If you have a volt meter, test the voltage from that wire going to the coil +. For an electronic ignition system to work, that wire must have 12 volts, no less.
***Disclaimer*** If the forum mechanic (or anyone else) wishes to correct me on what I've said, please do so, I'm just an old garage hack.

Mustangs have a resistor wire built in to the loom. The quickest and easiest way is to disconnect the original positive wire to the coil and run a whole new wire from your ignition switch to the positive side of the coil. This requires removal of your ignition switch which is not that difficult in a '65.
You will need circuit tester to hook it to the right terminal of the swith because if you connect to the accessories the car will start but will not turn off.
Only recently we have done the same conversion thats how i know how to fix the problem.
Lots of GM cars and all Mopars just run a ceramic ballast resistor which is simple to bypass. Bloody Fords had make it complicated.
Good luck.

ok i'll give that a crack tonight if I get a chance.
it's weird how the low voltage could get it idling but not at any revs....
Muzzy 66:
Come on Joel we are waiting to see how many lines of the instructions you missed..:smile:
Good to see your getting dirty again though lad.:drink:
Kroooozer:
Hopefully its not the flux capacitor or rack and peanut steering.....glad I could help
