you were correct pin 13, was not supplying any voltage. however I traced it back to the fuse box and it was dead at that end as well. I had a look at it seemed fine at the socket where it connects to the fuse box. so as a quick check, I bridged pins 11 and 13, to see if that was the end of my woes it wasn't :(
- the speedo is not working, I did take off the hose that connects to the rear of the speedo. and with the engine running and it not connected I could hear rushing air. I have re connected it. but perhaps I've not seated it back correctly I will try again. unless there is something else I might check?
- the ignition is always on. with the key out the ignition lights are on. How might I tell if this is a barrel or wiring issue?
all very frustrating as this all started when fitting a new head unit, then the immobiliser wouldn't un arm , So I removed it. it interrupted 2 wires on the ignition. that merely needed joining back up
