I have a cat with a keytroler scale that measures using hydrolic pressure. The problem is when the tilt is activated the forks drop. If you drive the forks also drop. Just started this after two plus years of proper service. You can power the scale off of a different power source and operation returns to normal. After contacting keytroler we moved all components outside the truck. No change noticed. My question is what kinds of problems have people had with electrical interferance or noise. How did you overcome the problem?
