I have two yamaha gauges on a SWII 200 (year 2000) The light for the speed/trim/oil is fine. But there's no light for the tach/fuel gauge. It's reads OK and I can see it during the day. But the light is out. Is this an easy fix for an electronic moron such as myself? If it's doable, can anyone walk me through it or at least tell me how to get to the bulb or fuse?<br />thanx
