power cart

[birddog]

This is very helpful. My interest is to be able to plug in to a power cart and preflight, review wx and get ATIS/Clearance/FMS prior to engine start. I have the avionics master switch which I interpet would allow me to accomplish some preflight items prior to start with power hooked up. If so Kyle's suggestion is a big help. I've been cautioned about engine over heating and thought the power cart might save some wear and tear. Thanks for the input.

The battery is isolated by a relay when the GPU is plugged into the airplane.
Avionics are isolated on the 337G by the avionics master switch. If you do not have an avionics master, the avionics are isolated by a diode and a avionics buss relay, this relay isolates the avionics buss when you operate the starter.
Starting the 337G with a flat battery and getting the battery online is no problem as long as the ALT RESTART batteries are OK.
The setup Kyle has in more than capable of providing the power you need and if you run a charger across the batteries when using it , saves it going flat.
We used this setup for starting Citations and Lears.
Saves a lot of money!!!
