HELP! I purchased a Gantry crane and the controller didn't have a "lock" for the magnet. So I purchased an older model control which had the lock option. After spending a couple hours tracing leads and trying to match the action from the wiring of the controls then trying different combinations to try to get it to work I got nothing. I know the crane works with the new model controller, and after getting frustrated with the wiring I just put the new model controller back in. But I REALLY want to get the old model version working.
The pics attached are the controllers and their associated solder points/circuit boards.
I'm a NOVICE when it comes to wiring, so any help in basic pictures or drawings would genuinely be appreciated. THANK YOU!
