Have 1987 Honda Big Red ATC250 bought new in July 1987. When I push the ignition button the green neutral light fades or flickers and starter will not turn. Battery is good, replaced starter solenoid relay because it was cheap, can kick start with no problem. Can turn switch to on and run wire from battery positive post to starter and the starter cranks the 3 wheeler with no problem. Any ideas on what to trouble shoot next? I've got an issue somewhere between the starter ignition button and the starter. thx in advance.
