Problems with Baron's mini tach

[Sylvester]

I purchased this tach a year ago without any problems to date. Yesterday while leaving Salisbury NC and heady about eighty miles to my house it quit near Gastonia NC. When I got home I shut of the bike and turned the key back on and the tack did not cycle like it should but the needle droped lower than 0. Today I put the key in and it went up to 8,000 and back to 0 like it should, so I started it and went for a little test run. After two miles it went back to 0. I stopped and fueled up and it is working fine again and has not acted up. I originally thoght something is loose but before I tear into it I was hoping someone else has some input. The tach may be bad also.

Mine started failing after a couple of years. Intermittently at first, then it wouldn't move at all. I found the cable (three or four wires inside) going to the coil, power, ground, etc. had a break in it about 18" from the tach. I cut the cable off about 6" from the tach and spliced in a black, 4-conductor telephone cord (the one that goes between the phone and wall). The telephone cord is made from stranded wire and plenty flexible. I staggered the spliced wires and covered with black tape. Not too unsightly.
