Re: Speedometer questions
I would just add that banging on the dash could be an indication that the dash cluster, printed circuit board or tach itself have a cracked or loose solder joint, or faulty connection.
If you do have an active hard code attack that first as the speed sensor does fail often.
Iíve had multiple cars/ vans w/ faulty dash connections at the solder joints.
Almost every Masi TC Iíve picked up has had no odometer or intermittent tach, speedo or both.
The mid 80ís-early 90ís all share the same electrical architecture, so these problems are all pretty similar.
I believe the vibrations, age and road conditions all contribute to these failures.
So, keep those struts and shocks fresh,... and try to miss those dreaded pot holes!
