Does anyone have a recommendation on a disconnect switch that could be mounted or installed in the battery compartment of a '79? I would like something that would provide an easy disconnect instead of pulling the cable all the time.


thanks

My 79 has the removable key on the positive side under the battery hatch. I can reach back and turn it off or on even with my five point harness on when I leave the lid open

I'm looking for a particular part# or brand, there are so many out there that would be fairly easy to install and hookup.

I have this one and haven't had any problems with it:



Battery Disconnect Link

Buccaneer

I use this one and have had it installed 25+ years in my 82, works great and can be easily turned on even if already in the seat.

Thanks ! this is what I needed.

I like the switch blade version.

I have the blade type on my car. We had the **** type on my fathers car and it was a bit of a pain. Had to align it perfectly or it wouldn’t make good connection.

Never had a problem with mine and it's been in there forever.

Blade type for me as well....Looks just like the one in Bloodzone's post above.

I also have the one suggested by theandies. It works well and the green **** can be completely removed like a key to take with you to make it harder for someone to start the car.

I also had a **** style and it was a PIA, switched to a knife-blade and it works fine.

I think the reason some have problems with the **** style disconnect and other don't is...
At least on the one I had, for a side post battery, when you loosened the **** the two halves of the unit were loose and moved around so you really needed to loosen it off a lot to prevent partial contact, and if you weren't careful it would come right out and down into the battery tray it would go.

With the top post, **** style the two sides are firmed joined and when you loosen the **** everything stays in place and it works great.

Maybe there are side post units that stay together like the top post ones but I don't know.

those cheap dissconnects with the green ****, and pretty brass plating.
are very weak, after 2 of them broke. I replaced with a real switch.

I mounted this switch, in the rear center battery box, as bonus you can lock the door !
this switch can be found at Harbor Freight.

Mooser

Not saying that the harbour freight switch isn't good but..., a Wurth (Battery Doctor) disconnect with the green **** is solid brass not brass plated. Maybe some of the Chinese knock-offs are plated but the actual brand name ones are solid.

One of my favorite anti theft devises on a car with a battery inside the car is using a gel cell (sealed) battery and an NHRA legal power cut switch. I use a brass strap to connect the switch to a marine type battery terminal. Hook the battery cable up to the other leg of the on/off switch. Then, I use a MAXI fuse in-line fuse holder and jumper across the terminals of the switch with a 30 amp fuse. When you turn the switch "off", the fuse maintains the circuit so that a radio/clock/ etc maintains memory but if the starter is engaged in any way it blows the fuse and kills all power..... and yes, I kept a few fuses in the car for when I forgot... lol

This is the switch I used on my 29 Model A. https://www.brattons.com/electrical-...ct-switch.html It is more reliable than the green **** style. If you check on eBay you can find units that are keyed, adding a theft deterrent as well. I would mount it away from the battery well, making it harder for a thief to disable it.

Just make sure you get the correct amperage switch. The linked switch is only 125 amps...

Thanks for pointing that out. I was using the linked photo as an example of the style switch and failed to mention needing a higher momentary amp rating. Bottom line, don't got to eBay and expect a $10.00 switch to do the job.
