1990 vn750 no spark

just bought a 1990 vn750 it has been sitting in the weather for about 5 years with the spark plugs removed. I have taken the starter apart and cleaned and reinstalled and the engine will turn over with a car battery. However I did burn up the starter solenoid before I turned the engine over with a ratchet to be sure it would turn freely. I have checked the ground wires (that I know of, have not recieved my clymers manual yet) and cleaned them. However I am not receiving any spark at any plug. Any help would be greatly appreciated! I am a newbie and love this site.

I may be mis-reading what you wrote, but you said you blew your starter solenoid? I'd have to check the wiring diagram, but the battery positive lead goes to the solenoid, then the ground cable goes to the starter... someone correct me, but you may not have a complete circuit now.

A couple of other things to check: what's the voltage on your battery? SHould be about 12.8v to start our bikes. Check that both of your coils are hooked up - front coil has a red wire and a black one; rear coil has red and green. (it is possible that both of your coils are bad, but not very likely- however, you can check the coils, too.) And take a good look at your spark plug wires - after 5 years, they could easily be dry-rotted. Plugs - did you put in new plugs, or are you trying to use the old ones? Get some new basic plugs for your trouble-shooting.

Good luck!
