Battery To Starter ???

[55 Fargo]

Okay on the trucks with floor pedal starter.

What can be added or wired to keep the circuit from battery to starter open when not in use, or if not being driven.

I have thought of these items, a battery master cut-off switch, either on the battery post or wired in the positive circuit from battery to starter.

Would a solenoid switch work, in this set-up, any ideas?????? PS I already have an ignition switch, wired, to not allow the igntion to get any juice when the key is in the off position, but that will not stop the starter from being live, when the battery is hooked up....

I think you want to keep the system open (no continuity) when the vehicle isn't being driven. The starter is dead until the switch is closed by stepping on the pedal although the post on the starter is hot all the time. It's the hot side for all of the accessories and ignition. I've used the green knobbed type disconnect, and a bettery disconnect on the ground side of the battery on all my old stuff - trucks, car, and tractors. A contactor or solenoid setup would work too, but they you've still got the control circuitry the solenoid that has to remain hot. Mike

I guess a battery kill switch would work using that method I would wire with long cables and put the switch in the cab. However if I want to kill power when not using a vehicle I just take one of the terminals off the battery and put it back when I want to drive

Thats whats on my 47 chrysler, but I have all new wiring, so I normally don't panic, if it is left on.

Hey my modern vehicles, and lawn tractor etc, are parked inside, but all is fairly new.

On the truck, there will be a master switch on the battery, I am like you, why take the chances......

A relay wired into your hot lead or ground lead, which one is of personal preference, will work just fine. cut the lead, wire to both main terminals and run the trigger wire to key switch. Unless key is on there's no power to anywhere on the vehicle. There's many relays (solenoids) to choose from but try to get one that requires very little amperage to keep it in the energized position. It runs a pull in winding and a hold winding. any partsman worth his salt will be able to set you up.
