I bought my 1991 Mk1 TDM with a loose connection somewhere than means in cold or damp weather the headlight/sidelight/clock lights & horn tends to not always work so have bought a 2nd hand switch to fit just wondering what else I should check. Already changed bulbs so know it’s not that end.
No Headlight Or Horn But Have Indicators When Wet?

Also check your earthing points. Sounds like when they're getting wet they are shorting. But yes your Multi-plugs under the tank where the cables from the handlebars meet the loom are prone to the green gunge. Give them a good clean out and get some sealant in there afterwards. This is good for this job

Interesting took the bike apart including tank off trying to find connection under tank only to find it had been removed and soldered together. Also, the large plug going into wiring loom was difficult to remove and looks like there is a burnt contact? Put new switch on with old one still connected to battery since didn’t have any bullet connector at the time and lights now turn on and work properly but not horn ?
Also wonder why it has 1 burned contact?

Admittedly it does have an air horn and some interesting wiring attached.

Regarding the burned connector, the usual causes are too much power being drawn (previous owner spliced in another circuit, such as heated grips or a 12V outlet), and also a dirty connector, which has oxidised and then arcs, or due to the higher resistance starts to heat

Oddly enough it does have a 12V socket wired to the dash as well as the air horn.
Think its time to call in the motorcycle electrician before I totally bugger it up.

The best way to find out, is to check the colour of the wire which has the burned connector with the wiring diagram, to see what it supplies.
Your earlier photo shows some fused 12V supplies coming from the battery positive, one of those is most likely going to be supplying the 12V outlet.
Your best friend is the wiring diagram and colour code chart

Well £252 later it should all be fixed. The wiring was in such a crap state most of it had to be replaced.
Apparently it was all connected directly to battery with no relays or insulated connections.

Wiring replacement, relay installation, hopefully replacement connector pins and a few hours of labour. That seems a fair price actually.....considering that the other alternative could have been that you were stranded in the middle of nowhere, when an important wire broke free.....

Got bike back this morning. Things seem to work now but still need to put it back together and give it a test run once the speedo cable arrives. They had to rebuild the horn and 12V Socket looms they also pressure washed it to test for water getting on contacts.
Didn't realise it was £60 to get it picked up and dropped back so could of saved some money there had I realised and ridden it to them but didn't think you can ride bike with all fairing removed.
Otherwise £6 parts and 3 hours labour. Plus VAT = £252

Bit of a tough break i would say, if you need the bike for transport then it needs to be fixed asap, hope all is good now.

As long as all the relevant lights/indicators etc are on it and working it shouldn't matter.
Just pretend it's been "streetfightered"

To be fair £60 was collection & drop off charge.
Just taken off the stupid exhaust tape as well since all it did was soak up water and make the bike steam. Thankfully pipes underneath are SS although very discoloured but not rusty. Just waiting on WEMOTO delivery of new speedo cable before i put it all back together again.

Burnt out pin would be explained by the lack of relay for the horn. Airhorn would take 10-15amps at most and that would be WAY too much for those pins hence the burn out. Fittting a louder horn would usually involve using the existing feed to the horn to feed the relay switch live and then from battery to new horn via the relay. 12v socket can be either ignition switched or direct to the battery. I wired mine direct to allow me to use the 12v socket to charge the battery. Saves removing the seat all the time!
But as others have said it seems about the going rate for garages these days. Luckily I know a bit about electrics in general so can do most myself.
Glad it's sorted.
