Coil to ecu link wire 8k ?

[FFMan]

from previous posts and from finding the fault with my 1994 5L griff, it was stated that the link wire (female spade on one end, bullett on the other) from coil to ecu should contain an 8k resistor. My problem was a poor connection in this wire so I've taken it off, once the terminals are clean it shows as a straight wire, no resistance at all.

My circuit diagram also doesn't show a resistor. Where should it be and did all cars have one ?

thanks

I don't know if all cars had one, I know that they're removed sometimes as an expedient fix when the resister fails but most I've looked at still had one strapped to the breather pipe or throttle assembly. I've never measured mine but apparently somebody else who did measure theirs found it was a little over 7k. I don't suppose the exact value matters, it's just to stop the ECU from getting too loud a signal from the ignition amp.

According to my Discovery data it is shown as being fitted 96' on ("fuel injection resistor 1", pre 95 ecu is straight to dizzy.

And yet my '93 V8S had the resister fitted, and they seem to be very common on the other hotwire TVRs too.

Agreed, it actually surprised me... I was really just seeing what LR called it if he needed to get one - I honestly thought they were on all of them also :confusedtoo:

Mine's taped into the loom behind the transmission tunnel. It doesn't look like a resistor at all - has a male spade connection on either end, black square body with Lucas and a part number in white writing.

I had the same problem(no injector duration when hot,restarting)i have the resistor inline though,terminal was green & corrodedproblem came all of a sudden,was one of those jobs i diagnosed quickly(more luck than anything,i was parked on the side of the road at the time)
