21 defender lonestar electrical issue

[Defender-Lonestar]

I have a 21 lonestar, did the pc1200 battery upgrade, also have superatv pin locker. Issue is when the locker switch is on and locked if I run the winch while plowing the locker motor runs and starts to unlock. When I let off the switch it then fully extends again. Verified by pulling motor from diff to watch it while running winch. Even does it if I run power straight from battery. Thoughts?

Call SuperAtv and see if they can help you?🤔

They were no help, said they have never heard of issue. I spoke to halo also since there actuator looks the same and they gave some ideas but issue still there
