MartinP Posted September 30, 2009 Report Share Posted September 30, 2009 Hry there all was out on the pigeons there a while ago and mistakenly put wire to the wrong terminals on the battery and blew the fuse in the speed controller. Just got around to replacing the fuse and every time i connect to the battery, it blows. Magnet works without it but is too fast. Fuse is 5amp, (small glass type). connected to a 13amp for a couple of seconds to see if controller was working and it worked. I opened the controller to see if any wires were touching but none were. Any ideas will be greatly appreciated. thanks all Quote Link to comment Share on other sites More sharing options...
Cranfield Posted September 30, 2009 Report Share Posted September 30, 2009 This question has been raised before and the popular answer is that this can happen if you connect up the rotary and controller with the speed turned up. Always do it with the speed turned down or preferably off, that way you don't get a surge to begin with. Its also a fair comment that some speed controllers can be temperamental, it depends where you get them from. Quote Link to comment Share on other sites More sharing options...
Lez325 Posted October 1, 2009 Report Share Posted October 1, 2009 You probably blown the reostat within the circuit board which controls voltage and therefore: controls speed Les Quote Link to comment Share on other sites More sharing options...
