Best thing to do is find a shop manual for it that has a wiring diagram. Manuals will show how to test the system. Try online or the dealer. I always buy a manual for any bike I get. It pays for itself pretty quickly.

Fine, leave the heavy-lifting to me. I'm just sitting at home watching Tropical Storm Fay go by anyway.

Sir: The best remedy for your bike's electrical issues is to follow the procudure below:

1. Drain all fluids from the motorcycle and remove the battery.

2. Submerge the motorcycle in warm salt water for no less than 36 hours and no more than 42.

3. Remove the motorcycle from the water and replace all fluids. Be sure to take the spark plugs out and cycle the engine a few times to get all the water out of the cylinders.

4. Discard the motorcycle.

Ohmmeter, a twelve pack and some of your buddies to laugh at you when you get zapped by a top coil.

Works every time.

No, but seriously folks, this man needs help.

Since your bike is an '82 it probably has electronic ignition, so I'm not going to tell you to look at the points. Has it got spark? If not there's this little electronic gizmo in the wiring harness over by the battery called the "Ignitor". Unplug this device from the hot side, and see if any juice is getting to it, if not, grab any hot wire when the ignition is on, and plug it into the ignitor. Check for spark. If no spark, check for juice getting to the coils, the key switch, etc.etc. cause now it's detective work, and you have to find where the electrical current stops, and go from there. Bypass the whole wiring harness if need be, and use a hidden toggle switch.

Then you can soak the bike in warm salt water, like Ken said.
