Fenner speedranger controller yr 1970 approx

Post by keebo »

Hi this is my first post
I have a 5hp single phase motor with the above controller the motor runs ok at 2000 rpm it has a speed controller dial when I reduce the speed the two 0.1 uF 1000v capacitors over heat I caught this in about 2-3 sec but they have cracked their casings and are prob damaged,
I might be in the wrong place with this thread
Can anyone shed any light as to why this is happening
Any help would be greatly appreciated
