No spark, Where to start diagnosis?

[lord cerveza]

Hey guys, new to the forum. been surfing through the threads for a couple days and i finally have a question.

I bought an 82 gs750t in the fall and tore it apart to paint over the winter. it ran when i bought it, had been sitting in a shed for years. i have put most of it back together but i cant get the plugs to spark. im pretty sure i have everything hooked up right, but no luck.This is my first motorcycle so im new to how 30 year old motorcycle electronics work. there is voltage to all 4 wires that go into both ignition coils, is the ignitor not properly functioning? how can i test these different electronic devices to find the problem?

also, i don't have any lights hooked up, just trying to get the engine to start right now, is this an issue? Thanks a bunch for any and all help. Ill get pics of my project up soon.

If you introduce yourself in the members forum, Basscliff will give you the welcome package keys to the kingdom. His site probably has a manual for your bike. Which will have a schematic and covers testing the igniter.

Make sure you really CHECK ALL of your fuses and not just visually either. Take the test light to each one.

And for the last question, king beer, no, the lights have no effect. In fact, I would leave them off until you get it running. At this point, all they can do is drain the battery, which is a bad thing.
And follow BassCliff's advice.
