Gas G9 Electrical Starting issue

bhunterp · 03-15-2018, 03:25 PM

New to the group. Have a g1 2 stroke and and a g9 4 stroke. The g9 is doing the same thing. I have no voltage at the switch, him the solenoid and the engine turns over but no spark from spark plug? Any help would be appreciated.

The G9 has power to the key, then to the pedal switch, then it splits to the coil/ignitor/start solenoid. Test those spots back to battery ground. If you have power and still a problem you may have a bad ground on something. The engine/gen are grounded everything else is usually wired back to battery and those ground wires are subject to faults as well.

I'll check again but didn't remember seeing any power on the key to ground

It has to. Power goes to key first and must pass key (key on) then pedal switch on, only then can it start and run. There is only hot wire. (G9)

I have no wire on my battery except and it could be backwards. Hot wire to solenoid and ground to motor

I think that stuff is wired off the generator, the other end of the battery cables. The small connections on the solenoid like to go bad also.

I will start ohming thru it to try to find where all the wires go and make my on schematic

On G9 its the white/red wire, it will go hot on all three when key and pedal are on. If so it is working properly. Then it may be a ground or bad part.

Posted on another thread but it was a grounding issue. Motor wasn't grounded. Grounded the motor. Nothing had to run another jumper ground to key switch
