I'm trying to install a trim guage on a 1991 BassCat Sabre with a 175 Mariner. I bought a new trim guage and a new trim sending unit. I hooked the brown wire with white strip from sending unit to "S" on back of guage. I hooked a hot wire (only when ignition key is on) to the "I" post on back of guage. My problem is my ground. If I ground to a known ground wire(ground wire off of the clock, that was working), the trim guage will not work. If I ground the guage to the steering column or one of the bolts holding the rack to the steering column, the guage will work. But it won't work by just grounding to a known ground wire. Is it OK to ground to the steering. I can't understand why it won't ground to a known ground wire and work. Any help appreciated.<br /> Kenny
