Hi all, I have an issue with the elevation on my torro sturmtiger, it was working but not anymore, I have spent a couple
of hours this afternoon pulling out the little hair I have left.
1/ the motor works from a battery
2/ there is power on the turret elevation pins

The elevation is green and brown.

1/ there as power at the mfu
2/ there is power at the pins when tested with voltmeter
3/the barrel elevates when connected to a battery
4/no broken wires

An odd one this, the two wires in my fingers go directly to the turret elevation motor, when I touch them on the spare
battery the turret elevation works, there is 7.6 ish volts at the first two pins, will have a fresh look at this tomorrow as
its now doin my ead in

At one point the 3 pin plug ( in my fingers) had another wire that I removed, it did still work after though.
