Suspect earth problem on the dash or instrument cluster on my EF.
Problem 1. is my speedo needle is not working and the tranny is locked in safe mode. The transducer is ok as I have swapped it for one that is working.
Problem 2 is the brake switch fail circuit has 12 Volts but very low amperage as though a bad earth exists. The brake switch diode tested ok.
Both power supplies come from the instrument cluster.
I have been told that there is an earth that gives trouble and it is a mongrol to get at. It is apparantly located in the centre of the dash near the dimister. Has anyone had this problem before or do you know where this earth connection is. Thanks.
Might even consider changing the instrument cluster over.
