I wonder if there are any Mud members in your area who'd help you with it? I don't have the experience or know-how either or I would.
Like @Ozark80 said. Get on your club page and ask for help. Cruiser heads, well most of them, like to help. Tell them your situation and see who bites. No, is the worst answer you can get.Maybe, I'm in college at Stillwater and my cruiser is now 45 minutes away at my dad's house so I'm having all sorts of fun trying to figure out my game plan here haha.
it is not unreliable. Mr T engineered that so your average soccer moms and mall crawlers dont freak out when the needle move up and down.For such a well-engineered vehicle, it's amazing how unreliable the factory gauge cluster is, even accounting for the age of these trucks.
