The dim-dip on my Torslanda has stopped working, I don't think it's anything to do with recent headlight change, the dipped beam is working, and dim-dip was working too for a while. Any ideas what might be the problem? I've checked the fuse but otherwise haven't a clue where else to look. I hope it's something I can do myself, recent garage bill means I don't want to incur any more expense for a while.

Hi,
So the headlight circuit is a tiny bit complicated with two relays, one within the dash and one near the battery under the bonnet. This page has a good explanation: https://www.240turbo.com/headlightrelay.html If the lights work at all, that suggests the main relay in the dash is working and the latching dim/dip relay next to the battery is at fault. I’m not sure how easy it would be to test it, but you could visually inspect it and the wires/connectors to it as a first step, I can see a few listed on eBay for not much money- but it’s be nice to know one definitely worked before buying. Cheers |

https://www.skandix.de/en/spare-part...-beam/1016421/ It could possibly be a old solder related problem and fixable. The link Bugjam sent is useful, there may be an alternative to replacing the o.s relay there. Best of luck.

It would be pretty simple for the OP to construct a rig to test the stepping relay, something like this: ![]() ... after momentarily closing the connection from 31b the relay should flip from dipped beam (from 56b) to high beam (56a); test using a voltmeter. ![]() Afternote: whilst writing this I found a test procedure that says more or less the same thing as above: https://www.davebarton.com/pdf/headlightsteprelay.pdf Einfach?

You can also try cleaning the switch mechanism on the base of the stalk. These can get gummed up with fluff and grime over the years.
