I am putting in a second battery.
Off that battery is a fuse block ( from a wrecker).
All the electrical mods will come off that fuseblock to keep them separate from the factory wiring.
I have a forklift plug on the front bumper so jumper cables can be "plugged in" without opening the hood.
I want to use a relay so the cables are only "live" when the button is being pressed. I found a relay rated 80 amps but I don't know if that is a high enough rating for the application. Batteries have 800 CCA.
I don't understand how the two numbers are connected?
Can someone help me out?
OK. I've googled Solenoids and looked at the Albright site. I couldn't find anything called a solenoid on the site. Some or their switches may be it but I'm still not smart enough to know what rating to buy.
