Finally got my bike to work after lots of little problems.
Last piece of the puzzle was getting my blinkers working. Tracked the issue down to being the blinker relay, so I bought a new one. Put it in, and it worked perfectly... but I couldn't just leave it alone.
Reading around on forums I saw many people recommend using a LED-blinker instead of the standard one, citing things like more stability in the blinkers flashing etc.. So I tried a 12v LED relay.
Short story, put relay in.. turned on the ignition and turned blinker switch to the left, loud humming sound coming from the area of the relay, then the sound of something electrical dying, then nothing. Now nothing works.. none of the dash lights, electrical starter, lights.. nothing.
Hopefully I just blew a fuse. What do you guys think, and what fuse should I go about changing if my deduction seems probable?
Thanks :)

I guess put back the old relay and replace the fuse...

Well a LED indicator relay drives LED indicators, not filament bulbs, which I assume you still have? These draw many more watts than LEDs so you've likely fried the relay and blown the main fuse.

Yep, still got the filament bulbs.
What strength is the main fuse?

It cured the problem and has been working fine since.

rubescube, the fuses are usually found in the fuse box ::) ::) ::) What bike is it?

What strength is the main fuse?Main fuses generally seem to be 15A looking at info for a few different models.
It should probably be marked on the fuse anyway, when you remove it.

If it's a 500 they only have one fuse running the whole thing, blow that and nothing works. If it was a 550 they have 3 fuses so blowing one fuse at least means something still works so I suspect it's a 500 and it's blown the fuse.The models CB500K2 (ED, F, G) and the CB500K3 have three fuses: 7A headlight, 5A taillight and 15A for the rest. I don't understand that so many are drawn to replacement by LEDS. If I read all these posts almost nobody seems to get it right the first time.
Then a little more on bulbs and LEDs. As far as safety, in particular attention value, I favour ordinary bulbs over leds. It may sound strange but LED brake- and indicatorlights do not draw as much attention as bulbs do. The reason is that ordinary bulbs glow on and off, where Leds are either on or off. In other words: with glowbulbs there is more chance you'll see something is changing. Do not forget that our brain is programmed to detect changes. Now we all blink our eyes from time to time. In such a blink a led can be switched on, where with conventional bulbs after you've blinked you can still see the lamp coming on. Some time ago I almost ran into a bus in front of me. I had missed glowing brakelights in my eyesight and the clean Leds had not alarmed me at all. And this was not the first time... Led lights could be a good thing for taillights and daylight running lights but I don't want them in my blinkers and certainly not as a brakelight. If other drivers are like me, I must fear I would run a higher risk being rearended.

Brilliant reply, totally agree ... look out for NOS Stanley bulbs (in orange packaging) at auto-jumbles .... a lot of modern made bulbs are sh*te

Interesting what you say Julie. I tried (quickly) to find out the electrical specs for LED relays, didn't find any so I assumed they can't switch much. Seems the attraction is that the flash rate doesn't vary with the load, which can still be filament levels, unlike the old flasher units. Agree with Ash's comments about the perception of LEDs.

It's a CB500 K1, and it was just the main fuse that blew :) sorry for being such a fish out of water, but I'm learning something new about my bike every day.. ;)

Anyway with our friends in Scandinavia we always have the chance it's about one of the 4200 C500K3s that were mainly shipped to them.

Never thought of it like that.
Has anyone ever considered how long it takes before the indicator bulb comes on after you press the switch? I seem to remember that it's a lot longer than that.

There is a relay involved so I'd have thought it's likely to be longer than with the simple switch arrangement of the brake light.
Post by: mike the bike on July 02, 2016, 12:19:12 PM
Every millisecond counts when it comes to braking. With some drivers, thinking distance is way too long and they need as much notice of braking as possible.
Post by: Chris400F on July 02, 2016, 12:54:46 PM
There's no relay with the brake lamp. Have a look at the circuit diagram.Thanks Mike, but I realise that, that's why I referred to the 'simple switch arrangement of the brake light'.

When I talked of a relay I was referring to Steve's previous post about the indicator, although reading again maybe his use of the words 'indicator bulb' confused things slightly.
I read it as referring to direction indicators where there most definitely is a relay and things won't happen instantly, but a delay before things happen isn't so critical.
Apologies I if have confused the issue.

Yes, that was me that got clobbered. Totally not my fault.

glad it was not you on your bikes,
any truth in the rumour BMW are cutting their prices,
they have found that they can delete fitting indicators,as they never get used
