I need a little help with my Tunze 6095. I have had it controlled with my apex for the last 2 years. Today i noticed it was not on. I have the pump on a few profiles on my apex. The propeller twitches but does not turn on. When i take the pump off the apex controller and use the Tunze controller it works fine. I cleaned the pump and there is nothing stopping the the propeller from spinning. I run my multi meter on my apex cord and its getting 10v to the pump controller just not spinning the propeller
