Here is how easy you can add your own battery cut off switch.
Parts List:
- Purchase a 4"x4" PVC Electrical Box (Home Depot/Lowes)
- Purchase a 4"x4" PVC Blank Electrical Box cover
- Purchase a 6" or 12" (BLACK) battery cable
- Purchase a Battery Disconnect Switch (You already have one.. like mine)
- Drill holes for switch (in blank cover plate) and 2 in the bottom of the 4x4 box for cables
- Mount the switch in the blank cover plate
- Mount the 4"x4" electrical box to the frame
1. Pull the 30 amp main fuse on the (+) POSITIVE battery cable.
2. Disconnect the existing ground cable from the frame bolt (other end is connected to the negative battery terminal)
3. Sand the frame around the bolt hole to insure a good connection
4. Connect the short (BLACK) cable you purchased to the ground bolt and tighten back to the frame.
6. Push the frame ground cable (other end) through one of the holes in the bottom of the 4x4 electrical box. Connect cable to the Disconnect Switch
7. Push the black battery negative cable through the other hole in the 4x4 electrical box. Connect the cable to the disconnect Switch.
8. Mount the cover with the switch to the 4x4 box
9. Install the 30Amp main fuse
10. Turn on the TT interior lights and hit the switch, if all works as planned continue to item #11, else (put the fuse in)
11. OK, now you can open that beer and admire a "JOB WELL DONE
12. Paint the box black to match the frame.
You could mount the switch to the battery box, but I am not a big fan of having the battery bump against the bolt threads of the switch if/when the battery shifts because of a nasty bump, and the less number of contacts in the battery box the better.
This project should take you about 30 minutes.... an easy job!
