Flakey speedo in EA
the speedo in my EA is not working. Well, it seems to work every so often and I can't pinpoint as to when it will or won't. It just decides to pop up every now and then. Of the average 500ks I do in a week, it will work for about 90 of those ks. How can I tell, well the odometer only ticks over when the speedo is operating.
Now, I have the EA sports dash installed from many years ago and the tacho is working fine, as are the other instruments, just no speedo. I determine the speed at the moment by the tacho. 2,000 revvs is roughly about 80kmh on a 3speed gearbox and 2,500 is roughly 100kmh, which equates to about 20kmh per 500rev range blocks.
I've had a part replaced that is connected to the transmission to fix this problem when it occured about mid last year but it's slowly degenerated over time to be completely useless at this point. The mechanic I used to have has closed up shop and he was a great guy to trust my car with, so before I go searching for another one in the wantirna/knox area of Melbourne, are there any suggestions in here as to what the problem could be, how I can fix it and where exactly on the car would I be crawling under or into to get the job done.
Thanks in advance,
