wiring question

[wolfj@rcn.com]

I have an r/c sailboat with a 'Graupner Regatta' sail winch and a servo
for my rudder. Not sure how the wiring is supposed to go, since there
is a power connector on the sail winch (in addition to a wire to plug
into the receiver, and a wire attached to an on/off switch).

If I connect battery directly to winch, and winch to a receiver
channel, the winch works fine, but the rudder servo (plugged into the
other channel) seems not be be getting power.

If I connect battery to receiver, and rudder servo to receiver,
(leaving out the sail winch entirely) the rudder servo works. So there
is no problem with the rudder servo.

So how do I get both to work? That is, how do I deliver power to both?

I suppose I could split the battery between sail winch and receiver --
that is, wire them in parallel to the battery...

Thanks!

Sounds like the intent is to provide a separate battery to the sail
winch, probably one with more capacity than the usual receiver/servo
battery pack. Makes sense since this servo probably draws much
more than the average servo. It might be isolated from the receiver
power to keep electrical interference down. (How many wires in the
winch server to receiver connection? Two or three?)

You could use a Y-connector to wire the battery to both, but you
should watch the run time on and make sure you don't empty the
battery in the middle of the pond. -Wm
