Well somehow the headlights on my M45 530C shorted out and blew the alternate headlight flasher unit.
It took out the rear alternate RED emergency lamps unit as well.
When I checked the wiring..,' Nightmare'! with Wires going here there and everywhere..three separate switches jointed in jointed out you name I had done it to make it work.
No it was NOT easy to accomplish ( At the time) as had not wanted the side lights, turn signals and or brake lights to flash as well, And they would have as all the lights are somewhat connected.
So, despite staring at all that, (Kicking a tire(Not too hard)), and not remembering or having a clue how I had achieved it, The circuit did not fix itself!
I cut Everything out!.
I rewired the lights to function as original.
Everything works,
So now to fit the Combined or alternate flasher unit ..Tomorrow. Both front and rear.
I will report....
