hey guys im not sure what this is but i think i fried it....
i was told its ok to jump the bike with a car battery as long as the car is NOT running....i jumped mine with a spare car battery, not even in a car, the bike started then i noticed smoking from under the seat and thought o s&*^! i took off the seat and the box im pointing to was too hot to touch and smoking...the other one was fine....any ideas?

Using a car battery should be fine as long as your bike is a 12 volt system, older bikes were 6 volts, but I believe by 84 they were all 12. If your electrical system has a weak connection or other issues keeping it from starting using a car battery might exacerbate them.

i see what you are saying....im hoping that the electrical system is all ok and maybe leaving a freshly charged car battery hooked up for a few min while it was running just over charged the system. the battery went dead because i had a fuel pump problem that caused me to run the battery dead while troubleshooting

Those are the ignition control modules (often called CDI boxes). They receive a signal from the pulse generator and tell the coils when to fire. If the bike is still running consider yourself lucky, they are expensive to replace.

Look into a low amp battery charger for your battery. Jump starting it is asking for trouble.

It's never a good idea to leave two batteries connected, this will ask your bikes charging system to do double duty attempting to charge both causing a large current draw and possibly damaging components. When jump starting any vehicle it's never a good idea to rev the motor of the jumped vehicle after it starts either, and the assisting battery should be disconnected immediately upon starting of the dead one. Good luck and keep your fingers crossed as smokeing electrical items is never a good sign.

OUCH! Yes those are your spark boxes. I would at the VERY LEAST look them over carefully to see if something important melted (wires, connectors etc.). As written they are &@%# all expensive and next to impossible to find for this model. So if you have a melted wire that could short out at any moment you will be royally &@%#ed on the side of the road!

wel thanks for the info guys.....i think i might be SOL on this one :-x
that was a dumb mistake i will never make again. the way it was smoking im sure its got to be bad, the battery is on a charge now, so we will see tomorrow
