- Hi, MG-Listers. After a recent dash R&R on my '66 B, I noticed the tach making some wild gyrations and then finally quitting. When I took it to a good electric shop, they said there was no wire hooki

- It's not really clear what the original problem was, or how it was fixed. The 66 tach has a loop of wire behind it, which is opened and closed in series with the points (distributor), and is looped a

- So a wire fell out of your car while driving along? Highly unlikely, more likely they didn't know what they were looking at. A 66 should have the white wire from the ignition switch going through an

- The white wire loop is probably not at fault. No one opened up the tach, did they? A loose or bad connection there would make the engine run roughly. The tach is an electronic unit with the loop as t

- I just had a thought, if the "good electrical shop" ran a wire to the 12v input from the LT side of the ignition (switched via the points) then it would be getting on average, what, 8v with a 60deg d

- Modified my tachometer on my '67 MGB to work on negative ground. Now it reads 4000RPM at idle and redlines with even the slightest increase in real RPM. Have I done something wrong in the rewire ( re

- This thing can and should be recalibrated. I had a similar problem, but not quite so extreme. Calibration is a difficult task. First, you need a way to measure the actual engine speed. I happened to
