trutrak load

Anybody know how many amps my TruTrak pictoral turn & bank instrument should draw? The unit didn't come with any documentation.

Phil,
Looks like the control head draws 0.3 Amps according to the manual.

Disregard. I just saw that you had the turn and bank and not the AP.

Yep, the servos draw a couple of amps, but the control head load is almost nil.

Belt and suspenders

I have the 2 1/4" Trutrak pictorial T&B. I had measured current consumption to be about 55 to 65 mA.

I installed a switch to select between the main electrical bus, or the alternate 9V battery supply. This allows the T&B to operate on emergency 9V power, and along with my other steam gauges, hopefully will allow me to get out of trouble when everything else electrical goes kerplunk.
