Stannah 420

Hi Im having trouble with a stannah 420. I’ve changed the battery but the lift slows down and eventually stops. I’ve tested the mag brake for 24 volts which it is getting. I put my multi meter on the motor wire and when the lift slowe’d down the voltage dropped to is this a problem with the main pcb ?? Ps this happens intermittently.

No its the slowing D2D switch at the back of the carriage that is being activated or its faulty. Best to replace it but you can try pushing the switch plunger in and out a few times as it could be a bit of dirt.
