Im looking for a battery kill switch that will meet the standards needs for the 10’s ( QC ) ..

I see a few but have no idea what the spec requirements would be required for the truck .

Has anyone ever used on or have real knowledge of these thing and what type is safe to use .
Im not looking for anything special just a manual type for disconnecting the battery due to parasitic voltage leak .

I don’t want anything that could damage or get so hot it melts or starts a fire !
 
So why can't you just pull a cable?
I am pulling the cable and looking to simplify the disconnect .. especially if I go somewhere ! The parasitic drain is from a damn small short somewhere , suspect a speaker wire , amplifier or something in the radio wiring system .. .. Simple fix a disconnect while it sits and as a theft control device .. it’s a pain in the ask to always have to raise the hood to disconnect the battery cable !
 
The parasitic drain will drain the battery to a no start condition overnight .. I already pulled the fuse to disable the radio system .. But I want to connect the radio back on and just disconnect the battery when it’s parked or sits …
I sure don’t want to go grocery shopping at Walmart and buy a lot of groceries just to get to the truck and it want start , damn my ice cream will melt and milk will turn to cottage cheese :confused:
 
The biggest question is the amperage required for the disconnect for the 10’s along with good quality .. Seems materials used are a question also ..
 
It's just an interrupt switch. When all is well, there is a minor battery draw from the clock. So the switch can easily handle that without arcing.
Don't buy the cheapest one and life will be wonderful.
If it does snap/sizzle when switching, you need to locate the draw anyway.

Im not worried about the parasitic draw . I keep reading and seeing specs from 100 amp to 350 amp ratings . Im assuming they’re rated to alternator ? Starting draw etc .. one article I read stated at least a 200 amp should be used but didn’t specify the type of vehicle used on , others just say car boat truck blah blah ??
Summit does show some higher amp ratings and are sanctioned and required for certain auto racing .. CRAPS GOT ME ASKING MYSELF TO QUESTIONS WITHOUT SOLID ANSWERS !

As long as you stay away from the 20 dollar ones made by Sunny Dong, you should be just fine.

Calculate the amperage of the truck by adding all the fuses together then buy accordingly??
 
So is it a super difficult task to pull each fuse to find the drain? I'm not sure how many fuses there are or how accessible.
 
Stock alternators produce 130-135 amps (about the same as a home welder), and the stock battery 750 amps, cold cranking.
So, even the $25 Sunny Dong Extreme may fall woefully short of expectations.

Right next to the battery there is a (mysterious) black box with a plastic "nut" on top. Take the nut/lid off and you will be witness to a rainbow of fuses for your enjoyment. The Relays are black and boring though, so don't expect much out of those.
