I have a 1996 RANGER SPORT R72 with a 90HP MARINER. My tilt and trim doesn't work on my throttle control, but it works up front and on the motor. I turn the key and i get nothing. No gauges, No sound, No start. I can pull start my motor and it runs just fine. Ive checked all the wires at the motor and every fuse i can find. Replaced every connection at the batteries still nothing. All my eletronics work from the dash like lights, horn, bilge pump etc.The last time it ran i had to wiggle the throttle control around to get it to start, is that where my problem is??? And if so what is the problem?? And how do i get in there to fix it??? I would love to get back out on the water so any help would be great thank ya'll....
