Main (High) Beam Stuck On
A while ago while on site (I am an engineer that travels a bit and I use my 33 for site work) I spent a few days moving about over some rough ground (a new defense base). When leaving site on the last day I noticed that my high beams were on (even when the headlights were switched off). Trying to dip them didn't do anything. I pulled the relay (standard 5 pin - double 87 poles) and the lights turned off. Normal dipped beam worked fine when I turned them on to check. Thinking it was a bad relay as it was very hot to touch I thought nothing more of it.
Today I finally got around to buying a new relay. I fitted it and what do you know, high beams on when headlights turned off.
So it was not the relay. Everything else in the indicator/headlight stalk works OK and nothing feels out of place.
