Battery box plug

[jorluivil]

I had a the same issue so here's what I did.

1. cut old wire off
2. strip off outer cover(strip off just a little more than you'll need)
3. flux both negative and positive strands thoroughly
4. solder each wire, make sure the solder gets inside the strands
5. measure each wires diameter making sure that each fits inside its respective hole, wire should have a snug fit
6. measure and cut off excess wire
7. if you have one insert outer protective cover over wire/cable
8. loosen screw on plug, do not loosen to much or they will come off
9. inside wires in their respective holes and tighten screw

When you tighten the screw it will dig itself into the solder and create a dimple as its tighhtened. The dimple will hold the wire in place and keep it from slipping out.

I went one step further and added marine goop to each hole where the wires fit and also gooped the section where the protective cover slips over the wire/cable. I insert and remove my plug every trip, its been almost a year since I did this and I have not had any issue to date.
