On the test drive to prove to myself that I had repaired the ignition, TR44SUE
had another surprise for me: The rev counter stopped counting revs. No, I
don't believe that this is related to my ignition work, as the tachometer is
mechanical. The tachometer drive comes from the base of the distributor, and I
did not take apart the distributor to that extent.
Unlike my speedometer, which has been very jumpy since I bought this TR4 in
year 2000, the tachometer has up to now been very steady and accurate (checked
against mile-markers).
What's the most likely cause of sudden total failure? Broken cable?
I assume I can disconnect the cable at the distributor end, start the car and
determine if the distributor-driven connection is rotating. Any tricks to this?
Can I put an electric drill motor on the cable to test the cable/tachometer
combination?
Which direction to I run the drill motor?
Will I ruin something if I accidently go the wrong way (on a speedometer I
would not ruin things, it has to deal with the car reversing)?
