Battery Shutoff Switch
Where is the best place to install a battery shutoff switch? It would be nice to have it readily accessible without lifting the hood all the time. Anybody use something other than this switch(besides battery disconnect) that works well? Looking for ideas....

Re: Battery Shutoff Switch
I have a 28 sport coupe that has a metal seat riser. I put mine in the front of the seat riser you cant see it! I ran the cabled thru the floor and put rubber grommets in the holes to prevent chafing.PCV valve grommets work great. i wasnt going to put one in until a short caused smoke to come blowing out of the instrument panel! i changed my mind quickly. I do agree that those mounted under the hood look terrible. You cant see mine!

Re: Battery Shutoff Switch
I have seen some installed through the floor board on the driver's side to disconnect the ground side of the battery. A word of caution, there are some poor repos on the market that are known to fail. The result is that the battery is then disconnected from the circuit and the generator can run wild and burn itself up.
I have also seen people use a couple of battery cables to make the connection that were not suited for a 6-volt system and it also increased the length of the grounding. The result is you will not get full power out of the battery when starting the car. Tom Endy |

Re: Battery Shutoff Switch
Here's my way:
No holes in metal. Just the floorboard. (extra cable is for my cell & gps) I can easily reach it standing at the door, or while seated. It's just under my left leg. I leave that corner of the carpet unsnapped. This may start a row AGAIN, but the safe place to put it is in the ground lead, not the "hot". Be advised, a cutoff will not turn off a running engine, it only disconnects the battery. The engine will continue to run off the generator. |

Re: Battery Shutoff Switch
Just a suggestion. Install the switch in the Ground Cable. This adds another layer of protection. If the ground cable between the switch and the battery chafes thru to the chassis, nothing happens except you loose the protection of having a shut off switch.
If you have the shut off switch in the "Hot" cable, and the cable between the switch and the battery chafes thru to the chassis, you have a dead short and the shut off switch will not isolate it. Again, Just a suggestion, Chris |

I need to put a cut off in my Tudor which I am trying to get finished. I did not think about installing it how you suggested. Very neat. I also did not mean to step on your post. I was putting my reply together while you were posting yours. I am just a bit slow with the typing. Chris |

Re: Battery Shutoff Switch
Mike, I like that idea and plan to do it. Could you explain the "plastic plate" part of the instructions and also why (or how) the second lead goes to the battery ground side AND the tranny cover bolt? Thanks. Bob

One switch lead goes directly to the battery ground terminal, the other switch lead to the existing ground strap hole in the cross-member that formerly went directly to the battery, but on the inside. Clean BOTH sides of the hole to bare shiny metal, attach another cable to the outside of the same hole (the battery side) and secure through both with a SS bolt, split lock, and nut. The cable on the battery side of the hole goes to a tranny bolt, being careful to clear linkages, etc. Secure as necessary. It will work without that extra ground lead from the cross-member to the tranny, but with it the starter sure spins fast! It's the ground connection Henry made through the engine pans, a connection that is not necessarily reliable for 200 amps if you have repainted everything. Apply dielectric grease or your favorite anti-corrosion snake oil to all connections. |

Re: Battery Shutoff Switch
I prefer mine on the floor right above the clutch. That way I can flip the switch with my toe.

Re: Battery Shutoff Switch
Mine is certainly not for a show car. Inboard of my frame rail. I have a steel plate with a shut-off/disconnect switch and two remote battery posts mounted. It is not visible without really looking under the car, but I could jump start the car without trying to access the battery-which in my car is underneath. I also have a small plastic box mounted to the underside of a running board which houses the connected for the remote trickle charger I keep the car on when I am not able to drive it often. Works well for me.

Re: Battery Shutoff Switch
I mounted mine off the starter with the bracket that the A vendors sell...and yes I have to open the hood to turn it on and turn it off.
That gives me a chance to look over the area for anything that looks out of place and to give the engine a once over. I do not drive the car every day so this MAKES me check out the engine area before and after each trip/ride/etc. I dont like cutting un necessary holes in any of the car so this way I didnt have to.

Re: Battery Shutoff Switch
Ditto! For the exact same reasons.

Re: Battery Shutoff Switch
Mine is a long way from being a show car, but i put mine next to the starter, i put the sw. in from the bottem up thru. the hole in the frame, i made a small plate aprox. 3/4 by 2 1/2 and drilled one hole to go on top of the sw. to hold it in place. i used the same cables, just moved them around a bit. it was cheap and easy.
you still have to open the hood to turn it on or off, takes about 10 sec's. Last edited by Louis; 09-09-2010 at 11:16 AM. |

Re: Battery Shutoff Switch
I installed my metal cut off switch on the seat riser directly in line with the shifter and interrupted the ground cable.

Re: Battery Shutoff Switch
I liked MikeK's idea for locating the battery disconnect switch so much I thought I would try it on my '30 Tudor. I added an on/off lever to make the switching proceedure more accessible in addition to having a smaller hole in the floorboard .
Thanks Mike K Mike H |
