Can somebody help me with a lil theory / method.
My Speedo on my 1990 S4 spider has stopped working. I notice on my Alfa Parts CD that this speedo is electronically driven. Therefore has a flexible shaft to a generator which must then convert that to an electronic signal to the speedo.
Question:
How can I go about tracing the fault as I have 3 potential faults causing the problem. The speedo, the electronic generator or cable?
Can I take an electronic reading from the connector at the back of the instrument cluster to prove that the speedo is either good or faulty?
Where is the generator ?
any help would be appreciated
