I installed a new trim gauge on my boat. I have a 1988 Johnson 88 spl. I wired the gauge just as the instructions said one wire from the sending unit and a ground to the ground post on the gauge the other wire from the sending unit to the S post and a hot wire to the I post on the gauge. The trim gauge works but as soon as I start to raise the motor the needle goes all the way up. It's like there is no travel on the sending unit only a small spot where it works. Is this the sending unit or do I need a resistor in line somewhere. Also installed a water pressure gauge. i have zero pressure with a hose hooked up in driveway at idle. The gauge is a 30 psi. still need to put it in the water and test it out at speed. The tattletale is spitting water at idle. Any input on these 2 items will be appreciated.
