Wiring a PG71 with encoder

[smcmahon]

We have a pair of AndyMark PG71 motors with Hall Effect encoders mounted on our Stronghold machine.

Through the encoder plates there is a way to wire in the red and black wires. We have done so, but they keep coming loose. I'm quite worried they will come loose during competition.

See photo. Perhaps our wires are just too big for the ports? Or perhaps we have loose screws? The wires are 10 gauge that came in the kit. We had 12 gauge in there originally, but those wires were much more stiff than the 10G and they were even more prone to coming loose, despite tightening the screws in the green plastic housings.
