I also need a new ignition. Please help. And I am as green as green can be with this mechanic stuff. You'll have to be pretty specific. Thanks for your time. | | | | | Joined: Jul 2004 Posts: 5,708 'Bolter | | 'Bolter Joined: Jul 2004 Posts: 5,708 | Jered,
If you power the side of the coil with the + on it from the battery, and alternately touch the wire from the terminal marked with a - to ground, the big fat coil wire should ZAP when held near a ground. This zapping is being triggered as you alternately touch that - wire to ground...that's what the points are doing for you.
Coils can go bad, but more often, it's points that aren't adjusted properly, and occasionally it's a bad condenser...usually the points though.

If yes, re-install it and remove distributor cap. Are the points opening when the engine turns?
If yes, stop the engine with the points closed. Pull the coil wire from the dist. cap and hold the end about 1/4" from the block. Now, with the switch on, separate the points with a screwdriver. A spark should jump from the coil wire to the engine.
If not you could have a bad coil or a bad condenser. | | | | | Joined: Oct 2007 Posts: 3 Junior Member | | Junior Member Joined: Oct 2007 Posts: 3 | I bought a new coil, spark plugs and spark plug wires. Got it all hooked up and still no spark. My ignition wire going to the coil wasn't giving a reading on the volt meter so we just hot wired a directly from the battery to the positive of the coil. Still no spark. We finally just scrathed a little on the points and then it fired right up. Now we have two new problems. The new coil got so hot it quit working. We put the old one back in it and we were back going again. What is getting the coil so hot? Our other problem is gas. The fuel tank sat for 20 years with a gallon or so of gas in it. We drained it and it was terribly varnished and nasty. The fuel pump is sucking good we just can't get gas out of the tank. Any tricks on cleaning out a gas tank. Thanks for taking the time to help out. | | | | | Joined: Mar 2005 Posts: 1,029 Member | | Member Joined: Mar 2005 Posts: 1,029 | Have you switched ftom six volts to twelve volts? If so, you may need a ballast resistor between the ignition switch and the coil. An internally resisted coil would also work. | | | | | Joined: Mar 2007 Posts: 863 Shop Shark | | Shop Shark Joined: Mar 2007 Posts: 863 | Pull the fuel tank snding unit and clean the pickup screen, then blow out the fuel lines from the pump to the tank with the screen off.
Tank cleaning can be done by a rad shop. | | |
