Electrics issue with ER-500

[iMark]

So I went to swap out some dead bulbs in my display clocks for the speedo and tachometer , replaced them and as only 1 of 3 was working.. after I was replacing them after minute or two, the one that was working stopped working too and one of them previously flickered, I've now just discovered before coming on my way home from work in the dark that it's stopped my tail light (and brake light) working (Usually check all my lights every time I'm out on the bike if its dark)

Everything else works, Headlight (Low & High), all 4 indicators, even the display lights for indicator Left and Right, Neutral and High beam..

The electrical diagram shows everything is connected to the R/BL and the BK/Y wires

the R/BL which head off to the ignition switch and the headlight switch (My lights are always on, can't turn them off) and that seems to be it..

BK/Y which goes to the headlight, city light, front indicators, horn button, "starter lockout switch" and something near the water temperature switch (a small circle within a circle on the diagram)
BK/Y goes to the fan switch (that still works too)
BK/Y goes to Fuel level sensor (also works)
BK/Y goes to the reg/rec
BK/Y goes to Main Fuse
BK/Y also goes to the negative terminal on the battery so that's the ground wire then.


So confused by electrics, this diagram seriously does not help either!


Gonna take it to the garage tomorrow but I'm just confused how everything else but those 3 bulbs and my tail light are working.

Locate your fuse box, look in it for a blown fuse, if you find a blown one then replace it with a fuse of the same rating and type.

I was under the impression if a fuse blew it would take all of them out since they are all on the same 2 wires?

No idea, checking the fuses isn't hard and it is the next place to go, it is very feasible that the instrument lamps, tail lamp, and front sidelamp are all on the same fuse, I don't have experience of your bike, but I have seen other vehicles wired this way.

It was just the tail light fuse had blown, why on earth is it connected to the lights that light up the speedo/tacho.. no idea! everything else on the clocks worked lol

Same with the GPZ..

It is unfortunate that that there aren't more circuits, but obviously money in production to this degree are often though as a wasted investment..

Just think from now on, that if your speedo lights aren't working, to remind yourself to check the rear lights first before replacing bulbs, as it once again could be the issue you just had, repeated.

you are so welcome.

Tail light was working at the time, until the fuse blew after I swapped the bulbs.. but the bulbs were definitely dead or at least 2 of them were.

@Stink yeah I'm aware of the older circuits where you could turn your lights off (that was good for hiding turn lights off and cruise along clutching the engine so it was quiet lol)
