Tired of replacing your ignition switch?
Burned up Packard 56 terminals?
Melted plastic connector?
Melted insulation on the wires?

Something thats been bouncing around in my head for a few years.

Here's what I did to my GT19 while repairing some electrical problems. Next is my New Holland S14H, my GT17, and My dads GT20.

We've always had a problem with burned up ignition switches and melted plastic connector. Mainly caused from a low battery.

My fix runs the charging circuit through a relay and not the ignition switch. I'm sure this fix will work for LOTS of lawn and garden tractors or anything that runs the charging circuit through the ignition switch.

Connect the blue wire from the rectifier / regulator to the # 87 terminal on the relay.
I used 14 awg/gage wire and insulated quick disconnects.

Connect the black wire from the auxiliary terminal on the ignition switch to the # 86 terminal on the relay or the # 86 terminal on the relay to the 20 amp circuit beaker.
Again 14 awg, insulated quick disconnects and a #10 ring or spade/forked terminal.

Connect the # 30 terminal on the relay to the non battery terminal of the amp meter.
Again 14 awg, insulated quick disconnects, and a #10 ring or spade.

Finally connect the # 85 terminal on the relay to a good ground.
Again 14 awg, insulated quick disconnects and a 1/4" ring terminal.

Now if you can find a relay, relay socket, pigtail kit Posted Image
Try a good local auto parts store, one of the ones that everyone used to goto 20 years ago before box stores like AutoZone opened up.

I just went through that yesterday, fixing a melted connector plug. Of course it happened at the back corner, the farthest point away from the shed. I should probly do a mod like this. Thanks for sharing.
