    I had a broken rear indicator, so swapped out the pair. Two wires per light.

    I thought this would be simple, and it wouldn’t even really matter which wire went to the earth and which to the live connection. However I’m now getting all sorts of random results from various configs. All indicators lit and flashing, correct side but too fast, correct but only v v dim.

    Is there anything obvious I could be fucking up?

  • So go back to the start, and check the wiring diagram (Haynes manual normally) vs the wires you have.

    I'd say, disconnect all the indicators, then plug in only one side. Get them flashing and happy, then disconnect do the other side. Then try everything plugged in.

    Fast flashing can be due to incorrect load on the blinker unit. Normally they stay on when you have one light not working (not enough load), and they blink fast when the wattage of the bulbs is too high for the setup (too much load).

  • Makes sense as I expect it’s a thermal reaction in the blinker unit.

  • Good shout re. unplugging everything. The circuit does seem a bit weird, like I think the front indicators are in series with the turn signal warning lights. Ah well. This stuff is exactly why I want to fit an M-Unit.

    It’s most likely that old metal strip type relay, ‘96 a triumph. Looks sounds and feels like one anyway. Have had the battery charging overnight just to be sure that’s not an issue, will try to make sure everything is dry as well. The rear indicator assemblies were off for a week.
