Hello Members:
My tach suddenly stopped working. Is there a common fault that I can attack quickly?
Thanks Jack
A blown fuse (F7) put mine out.
The later series Es had impulse tachs that contain some basic electronic components including three capacitors which, after 50 years, get tired and fail. Check these out first, otherwise West Coast Instruments for an electronic conversion.
Don’t know them (Google comes up with violins)… maybe West Valley Instruments?
Yes the electrolytic cap inside goes bad. Observe polarity, and you can use a slighly larger value in both rating and voltage without problems.
Contact Mike Eck to get the tach fixed/uprated, he did mine when I fitted the EDIS kit and and it works great.

Yes. West Valley Instruments. Morris Mintz. He did my tach. Quick turnaround at a much lower cost than the popular NEUS rebuilder.
