Battery Disconnect switch?

Anybody using one of these battery disconnect switch. I thought it would be handy to disconnect my battery. But the dang thing falls apart when you remove the Green connectivity screw? Any body else have this issue?

Re: Battery Disconnect switch?

Chas, why are you using this in the first place? I am familiar with this item, wondering how it benefits you?

Re: Battery Disconnect switch?

I've got one on the Buick. I think it was installed there by the PO as a cheap fix for a slow battery drain.

As usual, Andy is right
If it doesn't fit, force it. If it breaks, it needed to be replaced anyway.

I have to keep reminding myself this isn't a Z16 convertible, Evening Orchid Camaro, or factory 1966 SS427 and get on with it.

Yes, I use one on my 65 and I like the fact that it does as you say "fall apart". When I park the car I just unscrew the green knob and take it with me. The battery is now disconnected from the starter and it becomes a anti-theft device.

Re: Battery Disconnect switch?

I have used one and it works a disconnect of the battery. I had no problems and they are cheap.

Wink Re: Battery Disconnect switch?

I wouldn't use one. The contact area of that switch is too small for heavy loads. Les Saville's '67 GTO damn near caught on fire while he was driving it due to the negative battery cable melting.
Carry a pair of pliers if you have the spring ring battery ends, or a wrench for the bolt on ends to remove the cable. It ain't that hard to do and a lot safer.

On my other collector car I have a different battery disconnect switch and I have managed to get extended life out of the battery (7 years plus) by doing this whenever it isn't driven. Plus it serves as an anti-theft device as well. :-)

Re: Battery Disconnect switch?

I have been using the "Green Knob" disconnects for at least 15 years on all 5 of my cars. You dont have to remove the knob, just loosen it. Whenever I go a cruisenite or show, the first thing I do is open the hood and loosen the knob, even in my garage. No worries about a car fire, the only downside is the mechanical clock wont keep the time,, but at the beginning of every season, I set the clock at 12:00, and use it as a "Run Time" meter. I see these disconnects all over at swapmeets for $3-$4. and on ebay for $16. Don S

Re: Battery Disconnect switch?

I had one for a while but it caused my radio to loose all its presets.
What do you do about that?

Re: Battery Disconnect switch?

Some of these green knobs are sold with a pigtail fuseholder so you can run a small wire to the aftermarket radio memory wire, or you can add one yourself. A one amp fuse should be plenty.

Re: Battery Disconnect switch?

I had one of those green knob disconnect switches and although it did work fine, I got tired of having to open and close the hood just to turn it on whenever I wanted to go for an occasional ride in my car, and then reopen and close the hood again when I got back to disconnect the battery so I replaced it with one of these: http://www.painlesswiring.com/webcat...v.php?sl=30205. The big relay is installed under the hood and the red button inside the console. So now, all I have to do is to push or pull on the red button and I'm ready to go, no more need to open and close the hood!

Re: Battery Disconnect switch?

Good move Claude, I used a similar kit in my 70' and it is alot easier now to disconnect. Great theft deterrent also. Small discreet button underside of dash, out of sight.
