O.G. Posted July 2 Share Posted July 2 I’m trying to fit Cafe Racer LED headlights to my 2015 360R. After marking the light pattern of the old units on the garage wall I then temporarily fitted the RH LED and tried turning it on, nothing! And I mean nothing. No headlights, side lights, front or back, rear high intensity, number plate and no light on the headlight switch. The head light flashers do work on the old units along with brake lights though. The headlight and sidelight fuses are intact. The rest of the car seems to be OK. HELP!!! O.G. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted July 2 Member Share Posted July 2 Do you have the appropriate Seven wiring diagram and a multimeter? Have you disconnected the LH lamp? Please add a photo of the old wires connected to the new unit. Jonathan Link to comment Share on other sites More sharing options...
O.G. Posted July 2 Author Share Posted July 2 I have a multi meter but no wiring diagram. The picture is not the best but all I did was connect the connector. I also removed the old side light bulb out of its holder. I left the yellow and red connectors from the new light alone. Thanks Jonathan! Link to comment Share on other sites More sharing options...

I suggest completely disconnecting the new lamp unit. And then testing all of those again and letting us know the result. Jonathan Link to comment Share on other sites More sharing options...
SM25T Posted July 3 Share Posted July 3 Check the voltages at each connector for starters. If there is no voltage, you can't check the light module ! 1 Link to comment Share on other sites More sharing options...
O.G. Posted July 4 Author Share Posted July 4 I have returned the car to standard ie halogen and the only lights I have are the headlight flashers and brake lights. Something must have blown but not the fuses. What is common to just about all the lighting system? Link to comment Share on other sites More sharing options...
AlastairA Posted July 4 Share Posted July 4 I would suggest the grounding connections. Link to comment Share on other sites More sharing options...
SM25T Posted July 4 Share Posted July 4 Light switch. Wrong connection or internal failure. Relay ? Link to comment Share on other sites More sharing options...
PlastererPete Posted July 4 Share Posted July 4 Possible relay blown? Link to comment Share on other sites More sharing options...
Miker7 Posted July 4 Share Posted July 4 Indicator relay is different to the lights, so both wouldn't fail at the same time normally. Fuses are supposed to protect the wiring so are you sure you're checking the correct fuses? The fuses (i'm deliberately saying plural) are the only logical things to fail in my mind.

Miker7 Posted July 4 Share Posted July 4 Additional thought - did you change any wiring to use the new headlights? Where are you checking for voltage - could it be the new wiring is at fault and if you go backwards on the loom you'll find the original wiring is ok.

I’ve been caught out like this , my advise pull all the fuses and check , with continuity checks and meters it doesn’t load the circuit , I have seen a fuse (20amp) give a good continuity result but would not pass current , buy some fuses if different values and interchange to test good luck Link to comment Share on other sites More sharing options...
Tiddy7 Posted July 4 Share Posted July 4 I have fitted indicator fuses that glow when they have blown, as I was so fed up with pulling all fuses to find the failed one They are pretty cheap and have had no issues with them 3 Link to comment Share on other sites More sharing options...
O.G. Posted July 4 Author Share Posted July 4 Should be in position to do a bit more on the car tomorrow. I’ll try to cover some of your recent points now. The indicators work fine. I pulled and continuity tested the head and side light fuses. Hopefully the correct ones as per the various diagrams. I’ll try new ones tomorrow in case they aren’t taking the load but they looked OK through the window. Literally all I did was unplug the old unit and plugged the new one in and switched on. No wiring touched at all. Thanks Guys for all your suggestions, keep them coming. O.G. Link to comment Share on other sites More sharing options...

Member Jonathan Kay Posted July 5 Member Share Posted July 5 Assuming that you now have the original headlamp reconnected: 1 Set the multimeter to 15 V DC or similar. 2 Measure the voltage across the battery. 3 Release the light switch. Identify the terminals from the wiring colours. With one probe on a good earth throughout measure the voltage at each terminal with the switch in each position: OFF, SIDE, HEAD. Let us know the results. Jonathan 1 Link to comment Share on other sites More sharing options...
grumpy the 7th Posted July 5 Share Posted July 5 Cafe racer headlights. I had to pull an extra wire through the bracket to the headlight and cut and crossed over two wires to enable the lights to work as follows. Ignition ON and DLR lights on, the wires cut and swapped were the original pod indicator lights under the headlights which are now extra side lights (LEDs) and the original indicator wires now go to the headlights to operate the built in headlight indicators. I have a wiring diagram but am away in Coll & Tiree then Stirling for the next 6 or 7 nights Link to comment Share on other sites More sharing options...
O.G. Posted July 7 Author Share Posted July 7 Finally able to do work in the garage after the major disruption of meter changes. Jonathan - I did your test but there was nothing at any switch terminal with the switch in any position. I even tried ignition on and off. I tried the suggestion of pulling all the fuses and what did I find - fuse “L” flasher unit blown??? Can anybody explain why the only thing that works, the headlight flashers, the fuse is blown, and all the other lights, whose fuses aren’t blown, don’t. Unfortunately right now I don’t have a spare and I’m loath to junk another system by swopping fuses and blowing that one as well. Off to Halfords tomorrow, do I change the flasher relay as well. O.G.

SM25T Posted July 7 Share Posted July 7 Try working the hazard switch hard a few times, assuming it's an old style rocker switch. Link to comment Share on other sites More sharing options...

How are you identifying the fuses and relays? There are several different layouts... Jonathan Link to comment Share on other sites More sharing options...
O.G. Posted July 7 Author Share Posted July 7 I got it from the handbook and my spreadsheet I made up some years ago after I realised half those idents in the book were upside down. I will send you it if you want when I can find it electronically. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted July 7 Member Share Posted July 7 Thanks If *you can post that here we can then work out why there's no feed to the main light switch. Jonathan * Or I! : - ) Link to comment Share on other sites More sharing options...
O.G. Posted July 7 Author Share Posted July 7 Here is a picture that might help, as I say I will try to find it electronically. I’m thinking that the either the flasher unit fuse has blown with flasher relay frozen in an odd position or the relay failed and blew the fuse. O.G.
