Battery Disconnect / Isolator

[Phil Brown]

Ground side or supply side really not much differance. Most of mine are on the suply side because they need to meet the rule book for NHRA drag racing and there very clear on the master switch wiring. I know that were not racing here but 50 years of use with no ill efects I think putting the switch on supply side is fine, everything else in your car is switched on the supply side with no problems
