getting started on this electrical work. starting at the battery and working my way back lol.
4ga wiring from batter to kill switch. starter line off battery is also 4ga, though it doesnt need to be.
kill switch and panel finished.
heres the back for the alternator dump when the switch is thrown. the red wire goes to the fuse box and alternator. when the kill switch is turned off, this will get grounded through a resistor. its only a 10ga wire. hopefully its sufficient.
as you may have noticed, im trying to do this wiring correctly. and part of that is using as little solder as possible. crimping small wires is easy, and there are many crimpers available for small wiring. but finding a crimper for large gauge wires can be difficult and/or costly. and i know a few others on here will be wiring up a master kill switch so hopefully it can help them out too.
you'll need:
regular non-insulated crimpers
hydraulic wire crimpers ($50 from harbor freight) or a vice
appropriately sized heat shrink
heat gun or lighter/torch
wire in need of a terminal:
apply boot (this is on the kill switch with a pos lead from the battery) and move it out of the way:
slide heat shrink over wire, slide it up out of the way:
strip insulation off with a knife or strippers:
add terminal and crimp as tight as you can with the regular crimpers:
it may seem tight, but its not tight enough. it could wiggle its way out over time, not good. basically we just wanted to start the terminal off in folding over. grab your hydraulic crimper and lets finish this off to get it REALLY tight. put the terminal in the crimper sideways so the crimp makes it fold in half.
you now have a terminal connection that is better electrically and physically than a solder connection.
pull your heat shrink down, hit it with some heat to seal it up (i used the kind with adhesive backing). then pull down the boot over it all
thanks!
