Hello all,
My 1990 110 2.5TD has developed a fault with the aux fuse keeps popping. It's the top left one, and should be powering the horn, back fog light (?), this also affects the light stick when pulled back to put full beam on for a few seconds. The voltage is 12.8 when the engine is off. Any ideas on what to check or try? I'm guessing an earth wire somewhere or a short of some sort. Checked and it's marked as 20amp and have been putting in a 20amp fuse.
I've checked with new light Indicator-horn-headlamp dip switch
Disconnected all the connectors in the engine bay for the water pump
Swapped the hazard switch for another one
Removed the other switches such as lights and heated window (which was not connected to anything :D)
No cigaret lighter or USB connectors on either
All and any helpful suggestions welcomed.
