Upon returning from a fabulous 4 days around Wales with some of the other Grindelwald-Incompatibles from the UK, it seems my rebuilt car has decided it was time to eat its Harley Regulator (fortunately at home rather that on Snowdon in the rain....). Whilst on a short drive to confirm that I had cured the most dreadful handling issues (more on that in a future thread), I noticed that familiar acrid smell you only get from hot/burning electrical components and it was really strong. Voltage dropped to 12.6v and something was clearly wrong. All wiring to the HD unit (the usual replacement part no. 74540-1) was present and correct and the big 4-pin plug was correctly assembled. The stench from the regulator when I got back to the garage was horrible so I waited for the engine to cool and set about fitting the replacement HD unit I'd been carrying around with me for about 4 years. Fired the car upo and we're back to 14.1v again, so that was a relatively easy fix.

Has anyone else suffered a failure of the replacement HD unit as yet? See the picture below of the broken unit next to the new one. I have ordered yet another as a spare, which I will hopefully not need for another 4 years yet....

And despite washing my hands even more regularly than for COVID-19 reasons, I still can't get that smell off my fingers.....
