Hmm..reminds me a little about a problem I encountered once with my turn signals/running lights. This same thing has happened on two different dodges I've owned. I would turn the
left turn signal on and all the running lights, including the dash instrument lighting would blink faintly. If I stepped on the brake all the same lights would go on faintly, same as before, minus the blinking. Took me two weeks the first time to figure it out. Solution cost me about a dollar. wish I'd known that before I replaced the turn signal swich. This is what had happened. the light bulb in the tail light has two filaments. One runs on the brake/turn signal circuit, the other runs on the running/marker lights circuit. The filament for the brake-light/turn-signal had burned out/broken in such a way that the filament crossed the other circuit, causing the two circuits to be joined. this is why my dash lights and marker lights would come on dimmly when I hit the brakes or turn signal. What's remarkable about this as well is that if the filament had broken at the other end and crossed the other circuit nothing would have happened since the side with no voltage would be crossed. Well, the second time this happened (on another dodge,) it took me five minutes to replace the bulb and sovle the problem. The reason I bring this up is because what you described sounds as though when you melted the instrument cluster at the ammeter, it may have warped it enough to get some of the circuits to cross each other, causing the wierd behavior between circuits.
