My indicators and hazard warning lights flash too fast. So the hazard flasher unit looks original.The indicator flasher unit has been replaced by a round one. So I bought a replacement flasher for the hazard flasher and fitted it yesterday.When I connected the wires to the new "electronic" flasher it just lit up all the lights and didn't flash and also more worrying the unit starting smoking.
I have been recommended by others to fit this one :-https://www.carbuilder.com/uk/red-2-pin ... sher-relay

The "Lucas" originals don't have a good reputation for reliability and the ones I have bought seem to set on fire.

My question is can I fit this to both the hazard and indicator systems or should they be different?

I've used the linked electronic unit on both indicators and hazards on my Spitfire and indicators on the Dolomite.

I believe the clue is in the original units flashing too fast. The original units use the load of the circuit to heat a bi-metallic strip which switches the lights on and off. On Dolomites the flash rate is usually slow unless the engine is running to keep the voltage up. Unusually fast flashing indicates a high load or short circuit.

The replacement electronic unit seems also to be suffering from a high load. In this instance the unit switches on, but the short is in all probability causing a voltage drop to the timer chip, preventing it trigger. In this instance it stays on and overheats.

The original units protect themselves by their rapid switching.

You should be looking for a short circuit before spending any more time with flasher units.

Best of luck

Worth noting these dont actually meet any of the British standards - apparently because they don't match existing types of extinguisher so no approvals are relevent. It is almost certainly very effective, but if you're required to have a fire extinguisher for some reason (insurance, company vehicle, racing etc) it'd be worth checking that this actually counts as a valid extinguisher. It is certainly better than nothing!
