1977 Desmo 500 Lost Spark
No spark ......No key either ....I have the Red wire and gray wire connected....screw driver jumping the solenoid.....it's cranking over....Carbs are shooting gas....But no spark....I replaced the Plugs, put in a fuse, NaDa Sparka........I have a spare Solenoid should I try that? If anyone has any input that would be great ....Wiring is all original (could be that i guess).......I just wanna go for cruise around the block

Fiddle around with the ignition wires, you must have the wrong ones tied together. Jumping the solenoid will always turn it over, spark or not.
