Hello all!
Could anyone advise me on how to get my TR3 speedometer to read accurately
and steadily? I've taken this thing apart a dozen times, cleaned it
thoroughly and made sure all moving parts worked freely. But no matter what
I do, the thing still flickers in a 20-30 mph range and generally reads 20-40
mph over what it should, based on the tach reading. I keep re-setting the
needle position but it doesn't do any good. I replaced the cable
last year so I'm pretty sure that's not the problem. I'm trying to avoid
sending the unit to a rebuiling shop like Nisonger to save a few bucks. But
maybe there's internal parts that generally need replacing - anyone know?
I do have a TR4 tranny but I don't think that should make a difference, or
should it?
Also, I have a problem with my fuel gauge or sending unit, don't know which.
When the tank is full, the fuel gauge reads only 1/4 full. Before I put the
car in storage for 16 years, it worked fine. Now after restoration two years
ago, it doesn't. Can't figure. Can the gauge be calibrated? Should I try
to do it? Or is the problem with the sending unit? Can the sending unit be
calibrated or adjusted? Maybe I got the wiring wrong - any ideas?
