    Default Fast Pulses with Sharp Edges

    Above title should have read "RayMarine ST4000 Ram motor" instead of "test."

    In preparation for RtR, I needed to replace the electric motor of my X5 Ram. It uses a basic Mabuchi RC-555SH hobby motor but with some additional cross wiring near the neg and positive terminals.

    What are the 4 wires? I suspect they may have to do with handling the sudden change in current direction and voltage.

    I have found this on my 2011 model ram and a 2014 model. Crazy Rhythm did not have this on his RAM which is about same circa.
