I've got a slow drain in my battery. My guess is that it's from the 911 dash installed by a previous owner. After about a week, the car may or may not start. Is anyone out there using a battery cut off switch? There are a lot for sale, but many look similar and several have some bad reviews.
Thanks |

You should still figure out where the problem is.

You should still figure out where the problem is. --DD For sure. There's a parasite on board. I like cutoff switches, but, don't allow one to hide while you shut it off. Pull all your fuses, replace one at a time, tap the ground cable on the - battery and look for sparky. Doing this will hopefully narrow your search to one circuit. MSD is on all the time, as in it will charge the capacitors, so if you have an MSD disconnect it for this test. |

Mark, Thanks for the sequence, as I too, like many here, have got a parasite power drain. I was not sure how to go about narrowing down the offending circuit. If I don't leave a trickle charger on it I will have a dead battery w/in 2 weeks. |
