Ignition problems
[updated:LAST EDITED ON 06-Jan-03 AT 08:09 PM (EST)]Well my '72 has been dead for about a week with ignition problems. It first started as a voltage leak at the alternator that fried the points. Put new points in and checked the condenser, plus I replaced the coil for good measure. I tried it and got nothing. OK maybe I hooked something up wrong or it was a bad coil. Check the wires at the points and coil nothing loose or mis-connected. Check the coil and it was good. I thought that maybe I srewed up the ingintion switch, nope proves good. Me and My dad are out of ideas' I was wondering if anyone had any thoughts on it.
Thanks for any help,

Take off the distributor cap. Rotate the engine until the points are open. Put the coil high voltage wire near ground. Take a test wire and you should get a spark after you connect to ground and the coil neg wire and then remove it. Don't quite understand how the alternator fried the points.

Try a voltmeter or test lamp at the coil + to see if you have power to the coil with the ign turned on. You may have a open resistence wire between the coil and the ignition switch.

An easy way to see if it is a switched wire is to take a wire about 4' long. put Alligator clips on each end. Attach on end to the + side of batt. attach other side to hot side of coil. Crank engine, if it starts you have a wire fried between ignition switch and coil.

Just a note. When starting: 12VDC is applied to coil via the starter relay on the fender. Once engine is started and switch is set to run position than the 12VDC is applied to the coil from the ignition switch via the resistance wire or a ballast resistor.

Check for fouled wires, they are squishy to grab.
I doubt yuo could have yhis problem but it might be a thing to check,
starter housing arc that shorts out the starter,I seen it
and its ugly!
the metal from the housing arc welds itself
to the to something it shouldn't causing shortage.

X, You have a voltage problem. You should buy an inexpensive volt meter and trouble shoot the system. Check out the fuseable link. Fat wire probably blue with a plastic tab on it, near the starter relay. When excess amperage is flowing this wire burns out like a fuse.
