[QUOTE="Captain Jack, post: 910998, member: 243342"] Ho hum. The primary winding is open circuit :( (it's a two-pin plug, so no fuse to contend with) Didn't even bother plugging it in to test voltages. What's annoying is that the main bit itself seems salvageable, because there are two separate areas on the PCB. One - 36v side, which failed - looks after driving the motor via relays and the other - 12v side, which is still intact (based on what burnt out and what didn't!) - looks after the programming side of things. Of course, with the primary winding O/C, there's no telling what damage was done to the 12v side - if any. No markings on the transformer, so no idea what the replacement would be. And I wouldn't mind to replace it with a more reliable one - if such a thing exists ([USER=318162]@digi247[/USER] ?) [/QUOTE]
