Just an update on the knife switch I installed on my battery. It works great for preventing the battery from going down when the car is parked for a long time. I can let my Reatta sit for as long as I want with the knife switch open and the battery stays up just fine without periodically putting it on a charger. It does have a few drawbacks like losing the radio and clock settings but that isn't a big deal to me. It also loses the average MPG too. I thought the engine would run a little rough after the ECM lost power for a long time but so far that hasn't been a problem. The engine runs just fine on startup and runs well going down the road. I just thought someone might want to know how well my knife switch works if they were on the fence about buying a battery disconnect switch.
