No speedo this morning

[FFMan]

A sunny day, so a TVR day :-)

However, no speedo today (1994 Griff 500).

Is most likely culprit VSS and where does this lurk ?

I guess if i plugged in Rovergaige i could see if there was a signal to the ecu or not.

Does no VSS affect running, it died once at a roundabout and shunted a couple of times at low speed ?

TBH the reversing lights haven't worked for a while. I suspect the 2 cables connected to nothing underneath have something to do with that.

The MOT tester didn't seem bothered and i must admit it had slipped my mind until you mentioned it.

But the speedo has worked since the reversing lights were noticed as not working.
