Hey Bert,

I guess the right thing to do is cut off the positive side, leaving a small 
wire for your radio (if you have one).  So you won't loose any memory 
settings on the radio.

Subject: [vintagvw] Bettery shutoff switch


Volks,

I'm thinking of installing a main battery shutoff switch in my stock 1970
beetle.  I'd do it to protect against tiny current leaks during storage, but
also as an extra security measure.  I've bought a Dorman 300-amp battery
cutoff with removable paddle keys that ought to be good.  But I have a
question.

All the installation instructions talk about putting the cutoff on the
positive side of the battery, shutting down all plus going out to
everything.  But wouldn't it be more efficient (and easier) to put it on the
grounding (negative) side?  I'd replace the grounding braid with two short
battery cables, one from the battery to the switch (mounted through the
right-side rear heel panel, under the seat), and from the switch to a ground
bolt.

Any reason not to interrupt the ground (-), rather than interrupt the hot
(+) side?  Enquiring minds want to know.
