cut-off switch installation.

I intend to install a H.D. marine cut-off switch on my car. I am looking at just installing it on one of the battery cable. Its rated at 200 amps and can take the starter demand but I don't know if there is an advantage installing it on the pos. or neg. lead? The basic idea is to cancel any residual battery drainage that I am experimenting...the battery would go dead after a week or so of non-using the car.

I intend to look at the draining problem but for right now want to use the switch.
thanks, Ron.

You should hook it up to the positive side of the battery.

switch

[size=3]Doc here:

200 Amp might be a bit small, on a 600 CCA system...under full load..larger is always better!

What kind of Car are we talking about here? year/model/engine..

As For the Drain, THE single most common problem on internally regulated alternators is a bad regulator.

To test it, disconnect the battery, simply pull all the alternator wires OFF, and tape them up, then reconnect the battery before you park it for a period of time, If when you return it starts right up..get a new regulator or Alternator.

It makes absolutely no difference if it is in the positive or negative cable. The only thing to watch for is sometimes there is more than one wire coming off the post, more often with the negative cable. You have to make sure you open all the connections to one side.I have a couple of marine cutoff switches that say they are rated 200 amps continuous, 600 amps starting. If you is like that, you should be fine.

The best way I have found to find a drain is to get a 12V buzzer like a seat belt warning buzzer from a wrecker, take the positive cable off the battery and wire the buzzer in between post and cable. If it buzzes you have something on (turn off all accessories) or a short of some kind. Start pulling fuses one at a time until the buzzing stops and that circuit should be your problem one.
