Centered servo current drain
I've followed some really great posts on current draw with servos under load, but I found only one that discussed servo drain while centered.
I'm trying to track down a problem, so I'm measuring current draw on a 4.8v NiCd 1600 mah and pulling one servo lead from the Rx at a time. Most only show about a 10 ma draw (if that), but one shows nearly 130 mah draw under no load. It's not jittering, but if I jog it in one direction, it seems to find it's center and drops down to about 10. Jog it in the other and I'm up to 130 ma - centered - no jitters.
I think this is why my 1600 mah pack is only lasting about 10 minutes!
This servo's set up on a pull-pull - would a little bit of drag or too-tight wires cause this?
Thanks, all
