Just found the signal 10A fuse, it's fine!?! I swapped it with a spare one but it didn't change anything.


EDIT:

I checked all the other fuses, they were all fine. Then I saw a seperate fuse outside in a white box called 'park 10A', and yes that fuse had blown.

I swapped this with a spare, and now I have the lights and indicators back. I probably shorted it out when trying to measure the voltage of the rear light wires in the connector, I reckon the volt meter probe slipped a bit when I leant up to push the indicator button, shorting the park light.

So, I am back where I was. The fact that when the parking light fuse blew the indicators stopped working surley shows that these two circuits are joined in some way (bad earth) when they are not supposed to be?
