Have a 78 cx 500 with gl 500 engine in her.Problems starting,hit the button engine turns over a bit then stops and starts as if battery is dead.New battery in it,good spark and clean fuel.Will jump start from a car no problem (first time) even if i manage to get it to turn over a couple of times on its own battery still wont start.Took starter motor out tested on battery runs fine.Stripped it apart and looks good.Only thing is live bolt to take wire from solonid wire o0n inside has come loose.Any ideas or suggestions.Ive also noticed when plugs are out even 1 the problem dosen`t seem as bad.Conan
