If your Tuffy gauges blink off it's probably not an engine issue (coil, etc.). First thing I'd do is pull the ignition switch, pull all the connections (one at a time), apply a light film of dielectric grease and replace. A tiny bit of corrosion can do funny things to an electrical system. When you replaced you battery did you clean the terminals on the wires well or just hook it up? It sounds like you have applied other upgrades (with additional connections). You may need to check all of them.

Corrosion can affect any connection. It doesn't look like much sometimes, just darkened metal, maybe a little green but not always. Once clean, always wipe on a little dielectric grease to keep those connections more protected.

If that doesn't clear things up it may be the switch itself. I usually start with the cheap, easy stuff first and work my way up unless there is something directly indicating a major, expensive issue.
