Simplicity 700 Wiring

Recommended Posts


Gents this is a question merely on the AWG of the wiring. Thanks to this forum, I have a great schematic, so now it boils down to what to order.

I would think that the -BATT>GND, +BATT>Switch, and +BATT>SG Gen Terminal would be of heavier gauges; would this be 4ga like a larger tractor?

I assume most people go with 10-14 ga on the other wiring?

Input appreciated.

Well I think I may have used a little bit of overkill but I found a cheap inverter kit on amazon and hacked that up. Hope it all works fine.

In process of doing:

-BATT>GND, +BATT>Switch, and Switch>SG Gen all in 4ga, all VR and ammeter wiring made up with 8ga, and on/off to points in 12ga.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
