Master Kill Switch
« on: April 01, 2011, 06:55:25 AM »
I need some help and advice...

Wired a Master Kill Switch into my 02 TJ last year to pass tech in a competition. Works well, kills the vehicle instantly....HOWEVER, I seem to have some sort of mystery current drain now. After 2 days sitting, my battery will die.

I worked around this for the last comp season and would like to get this figured out.

I know NOTHING about electrical...and have been searching different forums. Lots of link on anti-theft...but nothing referencing a MASTER kill switch.

Can anyone point me in the right direction?

Thank you

What kind of swich is it? Does it just disconnect the battery ground? Does it kill the battery when its off(ie disconnected)?

Joey,
Does the kill switch kill everything? What about the winch? It is wired right to the battery? If so, that would be the first thing I would unplug, leave for a few days then check.

I did a Google search for "hot trannies" but nothing came up about oil coolers  :o

Worrying too much about mpg with a Jeep is similar to worrying about your sister's virginity. An ok thing to be concerned about but...

If you still have a draw, then the master kill switch isnt truly killing everything.

Turn the switch off and check for draw. Even this electrical imbecile can get that far ya fricken noob ;)

Its a long shot but my rig was doing the same thing. Couple of days of not running and it was dead. Alternator was rebuilt, battery load tested and passed, terminals cleaned, common grounds checked yadda yadda...
Started checking amperage across ciruits in fuse boxes an the multimeter showed me 130 ma to be the only draw when engine not running. This is accurate for the computer / sentry / theft etc and was as expected. You could spend the hours going through the fuseboxes like me or check your starter. Turns out mine was a shot starter. Drawing too much on crank.
Like I said... might be a long shot for you but that's what happened for me.
