Has anybody used these switches and/or are familiar with the wiring? I am interested in learning how to setup the LED so that they are dimmable. Any help would be greatly appreciated!!! Bill Hunter ________________________________ Message 2 _____________________________________ Time: 10:32:46 AM PST US Subject: AeroElectric-List: Starter Circuit For DADB From: William Hunter I am wiring a Dual Alternator Dual Battery system and I have a question about the starter curcuit. Naturally the only starter CB will be on one system bus and the question is what if that side battery is completely dead...if the second battery is still charged and I tie the bus would the second battery have sufficient power available to close the starter solenoid and start the engine? I know there is a discussion in the AEC about the dead battery not drawing down the good battery due to the 13.5 volts required to charge a battery but I was wondering about the starter circuit.

A PWM dimmer is most efficient, but some are noisy. If I remember right, Jim Weir had an article about LED dimmers in a recent KitPlances magazine. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=455342#455342 ________________________________ Message 4 _____________________________________ Time: 12:02:40 PM PST US Subject: Re: AeroElectric-List: Starter Circuit For DADB From: Charlie England If you're tying the buses (and effectively, the batteries), then it's electrically the same as 'jump starting' your car using an external jump start pack.

I will be running two Optima batteries so it will be a few steps above the jump start pack.

Draw the diagrams, and visualize all the connecting wires as having zero length. (Obviously not reality, but will show you the electrical circuit comparison.)
