Indicators and hazards

The fuse box from the old Nissan has been dissected into smaller more useful chunks for reuse. Luckily most bits were separated enough to run a saw between them. A bit of tidying with a flap disc in my angle grinder and it all looks pretty good.

I now have a couple of fuse blocks and an assortment of relay bases. One bonus part was a three pin diode, which has been used to build the hazard circuit.

The first circuit attempted was the indicators

A pair of relays are connected from the two red fuses and then on to the indicators via the yellow and green cables. The switching is handled by the Tex Magna which has been rejuvenated with a clean and a new coat of paint. Even the green light still works.

 The hazard switch is connected via the diode which keeps the offside and near side electrically separate. I will be ordering an LED type flasher unit as the old one doesn't fire due to the low current draw now it is on the switching side.

Amazingly it all worked according to plan.












The indicator switch has a clever mechanical cancelling mechanism. The roller is in contact with the steering wheel and acts on the lever arm as the wheel is turned back to the centre.

Very simple, the only issue is that the arm is not long enough for the diameter of the steering wheel.
