Installed a new battery cutoff switch......

[BobT-47P15]

My first cutoff switch stopped working.......presumably an internal problem.  The car would not start

with it in place and when I bypassed it the car started right up.

 

I like this style switch because I can place it on the firewall using a hole that was originally for a

heater hose. I can turn it on and off from the driver's seat.   One battery cable comes to a post from the negative side of the battery......another shorter piece of cable joins the other post to the front post of the solenoid.  I simply had the extra short cable made at the same time I had the other two cables done at a local battery shop They are double 0 size cables. 

 

This style of switches seems to have disappeared from the marketplace......or at least from the places

I know to look for them.  Found this one on eBay and had to pay something like $28 for it.  I looked for one at every swap meet I attended last year and did not spot a single one.  Hopefully this switch will last for a long time.

I made a little drawing to remind me of how this system hooks up........as I had kind of forgotten since unhooking it several

months ago.   I've made drawings of numerous other things under the hood and dash to help me know what I once did in a

year or more down the road.  Also..........pics of the new switch..........

That style switch is common, our parts store carries it as a regular stocking item. They're often used on emergency vehicles to prevent accidental battery discharge. If I remember, I'll try to get you the part number. It should interchange with everybody's.

That style switch may be available at marine suppliers as well.

all day long at Harbor Freight...

Quick look:

 

The battery cut off switch I see at Harbor Freight has no current specification.

The cut off switch I see on O'Reilly says 100 amps.

The cut off switch I see on Napa Online says 300 amps (but looks identical to the O'Reilly one with a 100 amp rating).

 

You may want to verify that whatever switch you get is rated for a couple hundred amps or more. . . A 100 amp switch on a 6v starting system would be undersized.

I saw that switch in Harbor Freight...the amperage was rated and marked on the container..a download of the switch booklet has a rating of 100 amp and 1000 surge...

If the switch did not come in a box......how would you determine what the amp rating is?

I didn't notice any numbers to speak of on my new switch.

 

I somewhere saw these switches are sold by Cole Hersee also.
