Like a lawnmower's stop button shorts the ignition coil. In this case the jack would short the coil until jack is inserted. You'll have to to check the wiring behind the jack to see what it does and if there now is a short somewhere. Just a wild guess.

Some jacks were designed to short or open a circuit only when the jack was inserted, such as disconnecting a speaker when a headphone was inserted. I'd try disconnecting one of the white wires at the terminal strip. --- David Carter david@carter.net On Wed, Aug 2, 2023 at 8:33=AFPM Finn Lassen wrote: > There is the odd possibility that the jack is designed to short when no > plug is inserted.

The need to jiggle suggests that the jack is worn. If you short the white wires together does the scooter power up?

Nuckolls, III" Subject: Re: AeroElectric-List: Non Aviation Without actually putting my hands on hardware, the key appears to be an ordinary, monophonic headphone plug. The jack may well be a stereo headphone jack. When a mono plug is inserted in a stereo jack, the 'tip' terminal of the plug would properly connect to the 'tip' terminal of the jack. However, there being no 'ring' feature on the plug, the 'ring' terminal of the jack would be shorted to the 'sleeve' terminal of the jack. Try a cliplead connection between the two wires going to the jack. If the scooter runs, then the hypothesis cited above is correct. https://mynewmicrophone.com/wp-content/uploads/2020/03/TRS_Jack_Plug_Connection.jpg Consider swapping out this 'too clever' disable switch perhaps with an ordinary toggle switch or perhaps a keyswitch?

Disconnect wires to 1 and 2. Does it start? If so that jack needs to disconnect wires from 1 and 2 when plug inserted. If does not start then wires from 1 and 2 needs to be shorted when plug inserted. A matter of bending the jack plug contact points (or replacing the jack).
