TR2/3/3A tr3 battery disconnect

[ekamm]

i've decided to install a battery disconnect the same as I've seen here a number of times. You know the one with the green screw knob. But when going to put it on I realized that It was made to go on the negative post and my car is + ground. Has anyone tackled this one the disconnect is obviously smaller than the post.

If you want to come over and look at mind, I have the disconnect on it.

Terry I may give you a call. Here is a pic of the cutoff that I have. I want to know if anyone has made it fit the pos. post as it is too small.

Is there any reason why it couldn't be used on the negative terminal even on a positive ground car? Seems to me you break the circuit either way!?

Here is a link to a thread that explains the reason why a ground break is best. Not that any break doesn't work.

I'm using the same cut-off switch.

Seems you may be able to spread the opening a tad and perhaps use a longer bolt. That is what I had to do with the braided ground cable I found at Pep Boys.

OTOH, I never clamp my ground cable tightly to the post... I leave it so it can be removed (in a hurry on occasion) with just a twist and lift. Still makes good enough contact (i.e. have never had a problem with charging, starting, etc).

Aloha Geo,

It seems like you have installed a disconnect switch, without any additional parts.

Happy Thanksgiving!
