Strange thing happened whem driving along the road and suddley the hazard light came on!!
been looking for its problems for 12hrs like grounding, cleaning CPU, dash removed, wee warning dash didn\'t have a lights at all,just digital clock working and its still flashing itself happy

You got an aftermarket alarm fitted ?
 
Sometimes this happens if the battery voltage gets low - the alarm seems to freak out

Also disconnect the CPU down by the drivers footwell and see what happens. It may be the circuit board in there thrown a wobbly,they can be replaced or replace the whole thing.
These CPU\'s do alter slightly between UK and JDM cars but the hazard and indicator are all the same and interchangeable.
Has this got a Mazda Alarm ? as this CPU controls the whole thing and integrates the horn,hazards and alarm bits together.

it\'s 86 UK reg, no alarm installed.
had been removed the CPU board( two parts) and have a good looking in and clean it and also got a spare one fitting in and still the same.
 battery charged ok and the horn working okay so the main lights.
torrow morning, starting to look at inside the dashbroad.

very strange, knowing its wee problem but where\'s it!


the hat,
lucky I\'m on dayshift next week and come along and looking forward to see it.
