Check the wiring at the connector blocks under the dash near the brake pedals, this is a common place for the brown wire to give problems. Roof electrics can be accessed by removing the 4 bolts holding the roof (on the outside) and the windscreen wiper nut. The roof will then lift at the front and be propped for access.

Both brown cables are going to two automatic fuses. It is a known fact that these fuses can corrode inside, preventing current to pass.

i have just gone through all the wireing on my 1690,you will be supprised at how wrong it was from the fuse box to light switch and ignition switch.facing forward in the seat look up the cab frame by the r/h step and you will find connectors for the wires that go up to top of the cab start with these ,as said easier to lift the roof .a google search will bring up a diagram 90 or 94 series will be the same or close enough the spades can come off the light switch very easily when re fitting the dash

The most common cause of power loss to the cab roof electrics on a 94 is the multi plug which is inside the cab frame on the rh side of the front screen, where you split the wiring harness to lift the top half of the cab off

These plugs corrode badly

The winkers are a seperate circuit so it should be pretty easy to identify them. They are NOT common to the brake lamp circuit.
If you apply b + to each wire end you can see what circuit is lit up and record it. Mine were light blue wirh a red tracer and green with red tracer .
My flasher unit failed to flash but does turn on the correct lamps so I just pulled off the b+ power wire ( mine was red) and made a jumper wire and installed a heavy duty flasher cube. Easy Peasy. For Hazzards I installed a switch that fed 2 seperate heavy duty cubes and spliced them into the directional circuits so each cube ran a seperate side only when the switch was turned on.
With this set up my "winkers" are very heavy duty and can power up a pile of lamps with out overheating and failing.
