1915 Maxwell Ignition question

Post by GasWorksGarage » Wed Jul 29, 2020 1:10 pm

On our 1915 Maxwell, we are not getting spark to the plugs. Coming of the ignition switch we have 6.4 volts going into what I assume is a relay.
We have 6.4 volts coming out of it going to the magneto. On the magneto are 3 wires The hot going in and right across a wire coming out and
on a pivoting arm a wire. On the one coming out if I jiggle the timer I get up to 3 volts on that wire on the pivoting arm wire I get .04 volts constant.

I have also attach pictures as well as pictures of the switch and wiring diagram on back of switch.

On the diagram the terminal unmarked I am not sure where the wire goes. To be honest I am not sure where the other 2 wires on the magneto run too? Any insight is appreciated.

My '15 Maxwell has a transformer coil mounted inside the frame. The two wires may be meant to go to it. This discussion describes it.

Hello, Do you have any original Maxwell electrical literature? I would get an actual Maxwell wiring diagram and use that as a guide as you troubleshoot your ignition system headache. Good Luck with your quest, you will probably be up and running quickly!

Hope this helps. Don’t know which ignition system you have.
