OK, yours is wired like this...

It runs 6V in LOW and REVERSE, and 12V in HIGH - it should take 18V without any problems. I think the easiest way to add an additional 6V battery, would be to tap into the loop on the top pins of the HIGH/LOW Switch. This will give you 18V in HIGH gear, but LOW and REVERSE will remain 6V.
Basically, you would remove the existing loop and run a wire from one switch pin to the new 6V battery Negative
, then a wire from the other pin to the Positive
. The polarity needs to reversed when attaching to the battery (Neg
), but if you get it backwards, HIGH gear simply won't work (nothing will be damaged). So you can just connect it, try it, and switch the wires at the battery if necessary.
I think the simplest method
for making these connections, would be to use jumper wires between the switch and harness, as 12VWiz shows in this diagram...NOTE: The diagram below does not show the correct LOCATIONS to connect the wires for your vehicle, this simply shows the best METHOD to use for the description above.
For your mod, there will be six pins instead of three as shown in 12VWiz's diagram. The top pins of the switch do not need to be connected back to the harness. So you would make four Male to Female jumpers to connect the bottom and middle pins from the switch back to the harness, in the same location they originally were, then create two Female to Female jumpers to connect the top pins of the switch to your new 6V battery (actually three jumper wires to include a fuse or breaker
). This method also makes it very simple to revert back to stock, as no factory wiring or components need to be altered.
You should use 14AWG or larger (lower number) wire, and be sure
to add a fuse or breaker - 30A should be fine.
