Faria Chesapeake Ss White 4" Multifunction 4 In 1 Combination Gauge W/Fuel, Oil, Water & Volts

here's a little video about my faria Mariah tachometer I just bought in 2006 boat and the only thing I wasn't working was a tachometer I read that these riots are known to fail after a while and my boat it's a kayak it's a high risk I it has a lifetime warranty on these tax rather than go through all that figured I'd try to fix it myself and a lot of people say to you know the needle sticks so what they say to do is you can maybe you can pry the ring off and open the case and then clean it out and that that likely will damage the ring I decided to do something different I drilled a tiny little hole on the side of the gauge just above the face you can see it in there and then I got in there with a needle file a very small needle file it's kinda hard to do this with the camera but let me show you get the needle file down in there and you just kind of work work the needle back and forth it
