Battery Disconnect / Isolator I currently have the six volt positive ground system in my car. My question is, which terminal do I put my battery isolator / disconnect on, positive or negative?
Thanks in advance! |

Re: Battery Disconnect / Isolator put the disconnect or night switch on the ground cable. positive.
with the switch off that will kill all power from the battery. the same idea as disconnecting your ground wire first before working on your car. |

Re: Battery Disconnect / Isolator The disconnect switch is good for assuring the battery does not discharge while the car sits, or for theft deterrence. But it is most useful when there is an emergency, such as a short causing a fire or the starter switch sticking. So put it somewhere where it is accessible.

one of the biggest causes for the battery discharging while the car is parked is the generator cut out. a night switch, as long as you shut the switch off, will prevent that. |

my father-in-law gave me that nickname in the mid 1980s, i don't know why, i wasn't even old then. |
Re: Battery Disconnect / Isolator 55 years ago , when I first got my A I took her to the car wash to clean the engine preparing for detailing the engine and firewall . Smoke began leaving the firewall wiring, so I flipped the rubber mat back , popped the battery cover off , and wiggled the positive ground battery terminal off ! Well it took me longer to type this than to actually disconnect the battery ! From then on when I reinstall the battery terminal I install it “ a little lose “ so that I can remove it by hand , wiggle and pulling it up and off , Fords original battery disconnect !

Hello, I have a disconnect switch on the 31 , connecting to the ground cable, the switch itself is mounted to to seat riser for easy access.Pictures don’t show very well, on other cars without the seat riser , it might be able to mount it on the cross rail under the seat .

Re: Battery Disconnect / Isolator Like looking for Waldo, I can't see the switch. Good idea though. Can you buy a wire long enough to reach the battery.

Re: Battery Disconnect / Isolator I have my disconnect switch mount in the floor just in front of the seat in my Town Sedan on the ground wire.

Re: Battery Disconnect / Isolator Y-Blockhead did you just mount it in a hole in the frame or did you have to drill one.
Do yu have a picture of it mounted. |

Re: Battery Disconnect / Isolator LOL. I just walked behind my '31 and the brake lights were on. I had removed the rear brakes yesterday, finally disconnecting the last brake rods (fronts were already off). Took me just a second or two to lift the driver's side hood and pull the fuse. It is a blade type, easy in and out.
I normally pull the fuse before any major work. Forgot this time. The brake lights are LEDs, so no big deal. I'll put the batt on charge while I get the drums ready to ship. |
Re: Battery Disconnect / Isolator Tom, here is a different angle. That is the brake crossshaft just below it.
