The perfect battery shutoff?
 

I’d prefer to mount an electrical shut-off in an easy-to-access location under the dash on my 34 Fords. What have you used in terms or product and how/where did you install the shut-off device? I’d prefer not to install under the battery access. Thank you.

I would use a latching relay used on motor homes. They will stay on or off without requiring power to hold. Mount near battery out of sight with under dash switch to activate on and off.

Ron, I fitted a battery cut off switch (older Lucas type with a twist knob) in the floor just in front of drivers seating position but behind the battery opening on my 34 Ford. This places the two switch terminals under the floor panel very close to the battery positive ground cable and easy to connect into. Don't have to run any unsightly heavy cables up the firewall. The floor mat or carpet just covers the switch if you want to hide it. Switch can be operated while you are sitting in the car and nobody can see you operate it. Good anti theft device. One hole (about 3/4") has to be cut into the floor panel though. Regards, Kevin.

Only problem with this relay is that it is 12 volt operation and wont work on an original six volt 33-34 Ford. Regards, Kevin.

Yes. I’m still 6v

Re: The perfect battery shutoff?
 

You could run a short jumper up to the floorboard with a race cutoff. Lot's of little battery cables.



I don't have carpet or interior.... so I just lift the lid and run a "loose" connection that I pull. Yep my 36 is a bit of a driver.


Interesting Idea with a relay/solenoid to a switch shut off. Maybe this needs to be invented.

Kevin do you have a part number for the cut off switch ? Karl

Re: The perfect battery shutoff?
 

I used a modern heavy duty battery isolator on my 33 and 34,I mounted it on the firewall,just above the throttle pedal,run a heavy duty cable from the bat,and the other just a short run to the starter pedal switch on the steering box.easy to operaste from inside .
DONT use the cheap plastic ones with the red key thing,they wont start good on 6V

I would not use an electrically operated solenoid as a cut off.

One of the main reasons you have a cut off is because of a wiring loom smoke down.

Then the electric solenoid will probably be dead for use.

I picked up a Cole-Hersee nos made in Boston like this, I think the current ones are made in Mexico or China.

Re: The perfect battery shutoff?
 

Awesome. May I ask where you found it? I would like to get one too.

Re: The perfect battery shutoff?
 

Boat supply places have this kind of stuff. And a lot of it is high quality.

Re: The perfect battery shutoff?
 

Those Cole Hersee 2484 battery master switches are rated for 175-amps continuous or 1000-amps intermittent so they should do the job. They are also available with a key switch and a key with a leg on it so you can actually turn it.

The Aerospace industry used to have some really good ones. Cole Hersee made a large single pole/double throw toggle switch P/N MS25106-21 that was great for a switch set up for either battery power or external power with three terminals but I don't think they make them any more (they never wore out). Most aircraft use electrical relays now days.

Speedway also has them and more

Re: The perfect battery shutoff?
 

Yeah, a wide variety at Summit - pages and pages > https://www.summitracing.com/search/...nnect-Switches

Re: The perfect battery shutoff?
 

Thanks Angledrive I just ordered one for my 32.

Re: The perfect battery shutoff?
 

Thats the one I use .

Check the amperage limits on those switches. I found one from Dell City that was rated for twice the amperage than the one I bought from MAC'S.

Re: The perfect battery shutoff?
 

I have one like corvette8n has mounted in the front of my Model a seat riser next to the adjuster knob. Easy to reach while sitting in the seat, and out of the way.

Karl, The Lucas switch I used was a NOS one I had and Lucas have not made them for years. But they are reproduced and sold in England by a Land Rover parts dealer. Continuous rating is 500 amps. (better than most) They sell on ebay so check ebay number 272181195680. They are very good and were fitted to Aston Martin, Bentley, Rolls Royce, Land Rover etc. Cost about US $25.00.plus shipping for the repro one which looks the same as the original Lucas. Regards, Kevin.
