Anyone use the 4 post Master Shut Off switch with a 1 Wire Alternator??? Do you have it wired as shown in the instructions, (with the Batt wire from the Alt going to the switch) or do you still run the Bat wire from the Alt instead to anywhere there is Bat Hot. (Ford Solenoid or starter)

sled the easy way to do it is to run the hot wire from the alt to the big wire on the starter you don't even need a 1 wire if you do it that way ake a stock alt and run the red wire to the post and then to the starter and the batt switch will disconnect it from the batt and it will not draw the batt down

werks for me

If you want your car to shut of all voltage. you run the hot wire from the alternator to the shut of like the directions say.

any other way and you should have bought the cheaper 2 post disconnect.

running the 12 volt charge wire to the starter wont work if your running a ford solonoid.

UNVRNO and Joe, where do I run the wire from the alt to get the batt to charge? To the hot side of the ford solenoid or to the hot side of the main feed to the switch?

You seem familiar with this type of switch...what is the purpose of running a second wire (smaller like 10 gauge) from the batt pos to one of the small terminals on the the switch (like the directions show)?

Do you have a 4 post diconnect?? if so run the hot charge wire to the small stud that has power only when the switch is on.

then run a 10 gauge jumper wire from the other small post to the large post that connects directly to the battery.


I have a brand new 4 post switch in my shop, Ill look at the directions to see if Im missing anything.
