Hi Ho-

   I put an electric tach in a '61 MGA. Worked ok for a yr but then
gradually seemed to die.  Since then, it stays mostly dead except for
an occassional blip where the needle bounces a few times then goes
dead again. Is there a way to check my wiring (should be ok)
or rebuild the unit?

thanks,
y

HI Yah,
On my '67 MGB I suffered the same problem. For what its worth,  the 
insulation on the little flexible LT lead inside the distributor had failed, 
( or maybe the plaited lead itself had gone brittle, or maybe both)  causing 
intermittant tach failure. I could not find an exact plaited replacement, so 
I simply used 2amp insulated wire and tucked in a small loop. That was 5k 
miles ago so it worked.

Worth trying if the systems are similar.!
Cheers
P

thanks!! will give it a shot & let u know how it goes-.

cheers,
