EDC warning light on MAN LE150C (D 0824 LFL engine)

ged:
… first I’m going to attack that connector…

Well I replaced the pin, made a tool to get the last one of the five connectors off, checked them all over, cleaned where necessary, gave 'em all a good spraying with WD40, put it all back together, reconnected the battery and started the engine. And bless me, the lights all do what they’re supposed to do now!

Well all except one. :unamused:

The indicator warning light flashes as you’d expect when the left hand indicator is flashing. When the right hand indicator is turned on it flashes once and that’s it. The indicators are working, it’s just that the warning light on the dashboard in the cab stops flashing after (always exactly) one flash. Weird.

It’s probably more grotty contacts somewhere but if there’s any inspiration out there as to where I should look I’d be most grateful.

And once again, thanks a million for all the great tips.
