RE: [APML] ST4 power requirements???

Hey Scott,

I realize I didn't exactly answer your original question. I do run my
ST-4 and Kendrick 5" heater from the same 12V 5 amp supply. When I'm
home (most of the time), that supply is plugged into household power.
Last summer at OSP, I ran the mount (G-11/Gemini), ST-4 and heater off
the same battery. No problems. 

When I got back home and tried the same thing, I did occaisonally have
weird ST-4 readings, so I moved the mount to a separate supply. It runs
off the battery all the time and it's hooked up to a solar charger.
Bear in mind, I never was able to determine what caused the weirdness.

Hope this is more helpful,
Alan
