Resistor wire

I installed new electronic ignition and 3 ohm coil. Took the boat out for a ride yesterday. After about one hour driving it cut off with a hot coil. Do I need to move the resistor wire? If so so will be electric choke, still work?

Any idea what brand and model of motor?

You can move the coil to see what happens.

What kit did you use? Igniter 2 takes 3 ohm iirc. Igniter 1 gets 1.5ohm. You need to bypass the resistor wire, easiest way is using choke wire. Pertronix often doesn’t work right and burns up coils

That's the kit I bought. Bypass resistor wire to where? When I remove it from the coil? Because I still need the automatic choke to work correct?

Tie it with the automatic choke wire. It’s 12v key on power. It can share the connection

Cap the wire. Split the wire to the choke and use that as your ignition wire

Moved the thread to the Mercruiser section

Undo the resistor wire terminal from the coil. Don’t cut it. Coil or fold the resistor wire, which is now loose, back to a convenient location and zip tie it to something. You might want to reconnect it back some day. A few wraps of electrical tape over the bare terminal would be good.

Yes. As Mentioned, verify your ignition kit and coil, and that 12v is supposed to supply the coil

Everything seems proper? I'm going to put new spark plugs in tomorrow. When I remove the purple wire the motor dies. Do I need to run a wire? Do i need a wire up to the key switch at the helm from coil +? Then remove purple wire?

I meant verify that you have the proper coil for your kit. Some call for a resistor wire and some don't. I think all of the modules need a full 12v. If you need 12v you need to run a wire from the choke. If the coil is internal resistor your then it also needs 12 volts. Otherwise, you keep the resistor wire. You aren't measuring correctly in your video. You want coil positive to engine ground. It should be 12+ v if not using a resistor wire and 8-9v if you are .

the engine starter key 12 volts coil ..... then the key 9 volts engine runs ...
purple wire resistor 1.8 resistor coil + engine on !
