My mobile lathe is a Woodfast midi that I converted to variable speed with a 110V dc motor and transformer/speed controller (like this one Input AC220V Output DC0 110V Motor Speed Controller 600W AU | eBay (http://www.ebay.com.au/itm/Input-AC220V-Output-DC0-110V-Motor-Speed-Controller-600W-AU-/141932183693?hash=item210bd1408d))
. When drilling holes in pepper grinders I normally lower the belt down to the lowest speed pulley, but today I forgot when I was doing a large hole, and the whole thing stopped.
Couldn't see anything obviously wrong nor any of my reset switches did any good. I checked the fuse in the transformer and sure enough blown. Replaced it but just blew straight away again. Disconnected the motor and fuse doesn't blow. Checked output to motor from transformer and it is 348V DC in lieu of 110V?????
Any suggestions on what else I can check/do?
