Tim Babcock Posted February 28 Share Posted February 28 I am working on a small MS-B Challenge fan. Someone put too long of screws that hold on the cage and it pushed in the coils. This was one of the reasons it was running hot. I have used a pin to separate the damaged areas to try to get to the short. I also applied red coil spray. So far I have not found it. Is there any short cut to fix this or is it just keep picking the coil wires apart? Quote Link to comment Share on other sites More sharing options...
Tim Babcock Posted March 6 Author Share Posted March 6 (edited) I think I have the short fixed. It now runs pulling .53 amps. It still has a bit of a noise in the bearing. Edited March 6 by Tim Babcock Quote Link to comment Share on other sites More sharing options...

Tim Babcock Posted March 6 Author Share Posted March 6 It has two issues, one was a broken winding I repaired, the other was a direct short. Withe the direct short it would run but it would heat up fast. Now it runs, draws about half an amp and only gets warm not hot. Quote Link to comment Share on other sites More sharing options...
