Hi Team,

I have purchased some 37inch super singles and have installed the humminbird speedo calibrator and now my speedo doesnt work nor does my odometer. Im confident ive installed it correctly as i used the wiring diagram from the unit and the truck diagram. Im wondering if the adjustment things are not set correctly. can anyone point me in the right direction for the correct configuration as per the attached pic? truck is a 2002 NPS 300. Thanks

maybe start with switches 6 and 7 on, test frequency of 500 hz.

also need to know if sender is hall-effect or inductive, switch 3

I don't have one .... my Mitsi is cable driven.

Thanks mate. I had a play and managed to get it working just need to check that its accurate now. Ill get the GPS out next week and get it set. The manufacturer conveniently set it for me and then sent it to me. Truck super singles gives a percentage to get it preset which was convenient. I have attached a picture of the settings in case anyone else is looking.
