I would suggest you remove the battery connectors, then put a little "bulb grease" on the bolts and reconnect. Just to be sure...

You should have a manual by now if you are a tech.

The fuses are under the left side cover on many models.

you can also clean your fuses:

Abad cable can go intermittently open - OR display huge resistance to the charging system.

this can cause the charging system to overload.

No codes thrown. That is why I suspect the ignition switch. The tuner is a super chips new tuner. I forgot the name. First 50 were half off with hdforums as a discount code.

Main breaker

Your 07 does not have a main breaker, but does have a main fuse. If it were me i would check all your cables especially the ground cables.

A friend of mine had a similar problem. Bike kept running crappy, and the speedo would shut off and come back on. The bike was throwing all kinds of codes but I couldn't find out what they were without the internet. I checked all the connections and wires, couldn't find anything wrong. Just for the heck of it I checked battery voltage while running, seemed ok at an idle, slightly high. When revving the engine the voltage started to spike to 16V+. Checked the regulator and sure enough it was bad. replaced it and all the problems went away. Not sure if you have done that yet but I figured I would throw it out there.
