I found the original Lucas ammeter in my boxes of parts for my TR6.
I took it apart to clean it and check it out.
Yes the writing on the gauge face had pretty well turned to powder and nothing more then removing the glass sent most of it into the air. That will be dealt with soon enough but...
Once inside I have the pointer, a small magnet and a coil of wire that appears as though it used to be connected at some point. In the center of the coil the wire appears to have burned in two.
Just to be sure, is the wire supposed to be one length of wire (not two pieces) and will soldering it back together work? I was concerned that soldering it would change the resistance in the wire.
