Hey guys

I changed the flasher unit on Lance yesterday. Everything seemed fine but then while testing the stop lamps just stopped illuminating. At first they were working after the unit was replaced then they went out.

Test results so far.

Stop switch is fine I think. Tested and works.

With everything plugged in I'm getting 12v on one side of the switch and 0v the other side.
If I unplug the return to the stop lamps the switch reads 12v both sides.
I've got 3 ohms across the lamp side of the circuit from the switch with the switch disconnected ie running through the lamps to earth only, this seems about normal for the lamps.
I've tried plugging the old flasher unit in just in case.

I'm assuming there is possibly a high resistance joint somewhere possibly in the dash. I'm almost at the point to pull the whole dash off, I can't see how it would be on the other side of the circuit nothing has been touched outside of the dash.

Any advice would be awesome cheers
