Help! Dead bike.
« on: June 30, 2016, 10:32:26 AM »
Stupid, stupid stupid...

I 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 swapping in 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  :)

or, you've fried the entire electrical system, a fuse should go "poof" in my experience.  But fret not, I can't imagine a relay and led blinkers destroying the bike.  Swap all your fuses out.  They are roughly 60 cents a pop and you should have spares anyway.  Use moto fuses, not the longer auto ones.

Most importantly - what bike?  Year, Model etc. That's very important info and should be in your signature.

Look at your manual for fuse amps, location, etc.

Don't know what bike you're talking about, but the relay on my 78CB750 is awfully close to the connections to the voltage regulator. If the relay casing shorted across the contacts to the regulator then that would be a nasty short...  :(
