Evening everyone. Looking for help tracking down an electrical fault on a Jan 1993 Mini Sprite. The hazards, indicators and interior light have stopped working.
Looking at the Haynes Manuel I've struggled to find the right wiring diagram, the 1986-onwards show separate flasher units for the hazards and indicators, but I believe this changed to a single flasher for both from 1993-onwards (under the dash to the right of the steering column), so I'm using the redrawn diagrams from the forum which look a much better fit.
Given the hazards, indicators and interior light are at fault I checked the line fuse 1 and found it burnt out. Changed this fuse and have 12v on the fuse input, but doesn't fix the fault. Retested the new fuse and it is ok (image 1).
Next tested the 12v input to the flasher unit (pin 49 on the relay installed but pin 85 on the diagram), no 12v found. Also tested the 12v input on the interior light but again found no 12v (image 2). I'm a bit dubious of the quality of the earth doing these checks, using about on the seat clamps for the black probe.
I've also pulled out the hazard switch, taken it apart and cleaned it up.
Tried jumpering pins 49 and 49a to bypass the relay, but no change, same with the hazard switch.
Has anyone got any ideas on where to go next? Other than replacing the hazard switch and the flasher relay I don't know where to go and given I can't see 12v on the relay input, seems a redundant check.
