ok...everyone does not seem to understand my question. let me try this one more time..........................

Question

I have a 1993 Yamaha FZR600R, my headlights dont work, my brights indicator doesnt work, the bulbs are fine, the fuse is fine, and the wires seem to be ok. i washed it the other day and thats when it started. is it the relay....the switch....ground...or something else? SOMEONE HELP ME WHO KNOWS WHAT THEY ARE TALKING ABOUT...PLEASE!!!!

Answer 1

Just go clean your STARTER PUSH BUTTON CONTACTS with some WD-40.

Stop and Realize what NORMALLY happens to your Headlites when You push the Starter Button .

Do Your "Always On" Headlites Stay On while Starting?
(When they're working normally,that is)

No,of course they dont.

The Starter Button is a DUAL SWITCH.

It itself is the circuit interupter that Momentarily switches Headlites OFF when You push the Starter to reduce the load on battery.

Soon as you let off the Button,,,Headlites come ON again.

Power from the main power bus goes TO the Button.

Button has TWO contact terminals OUT.

Normal Position>NOT Pushed==Power is Connected To HEADLITES.

Battery>>>>>Starter Switch>>>>Headlite Hi/Lo Switch>>Lites


START Position>>>Button Pushed in,,,,,
The Switch's Power-IN Contact swings AWAY from Headlites to turn them OFF,,,
and then Connects with Starter Contact to send that power to Starter Solenoid.

Let off the Button,,,Starter Quits Spinning,,,and Lights come back On


12Volts Line IN to Starter Button is ALWAYS connected to & Powering Something.
Either Starter or Headlites.

Since each "Downstream" contact is Separate and Individual,
It's absolutely Possible for Starter to work perfectly Normal on IT'S contact,,,
While HEADLITE Contacts Dont Work.

Or Vice Versa.

Power To the Button simply swings back & forth between Starter and Headlites.

IF Your Starter Button WORKS,,,
then Obviously power is getting TO the Switch

And Lites "SHOULD" work when you are NOT pushing the starter button.

All sorts of crap is POSSIBLE.

But a Mystery Headlite Failure AFTER WASHING??
*ALL Headlites,,Both Bulbs ,,Both Hi & Lo beam
*Hi-Beam Indicator
*You Did not mention the Instruments back-lights---
They dont work either,huh?

ALL that and ONLY that is on that lighting circuit.

The Power wire going TO the starter switch Should Be
RED/yellow.

Out FROM the Switch>>
BLUE/White goes to Starter
BLUE/black goes to headlites

Simple switch,,,
Bust it open and see what's up with the Contacts for the Blue/Black wire -to-Red/yellow(I THINK it's R/y)

Careful what ya poke around in there with while KEY is ON,,,all that crap is HOT and WILL do Fireworks if shorted to ground.

You may be able to just hose it with WD-40.
You MIGHT have to remove the contact plates and polish them a little with some very fine sandpaper

.................................................................
Oh Yeah,,,,"What Happened to CAUSE this?"

Lemme call upon my Psychic Powers to View Back into Time

Ahhh,,,I can see it Now!

You Washed Your Bike.
Then You Started it!

Seriously.....
Bike was OFF when Ya washed it

Got a bit of water in the switch,,,however

The LIGHT contacts are "always on" and conducting.
So No Prob when you switched Key On.

But when you Pushed Starter Button,,,
You SEPARATED the Light Contacts to break the circuit.

Then when you Released the starter button,,,
You made contact between Wet Contacts under a High Amp Load connection,,,,all the Bulbs.

Headlight bulbs alone are about 4+amps EACH,,,
Maybe 10Amps running thru that contact.
It just Instantly oxidized the contacts going to the lights.

It Doesn't bother the START contacts because that draws very little current

.................................................
I cannot Gaurantee you that where your prob IS,,
but it's By Far most likely suspect ,,given the syptoms and scenario you describe.

Try it and see what happens.

You can half-assed "Test" it with a " jumper wire ".

To do that you must be Cautious because theres so much amperage draw from the Bulbs.


*TURN KEY OFF
*Find end of Starter Switch Harness where it plugs into the main harness.
*Stick a short piece of wire into BACK of connector block.
*Go from RED/Yellow to BLUE/Black

Turn Key on and headlites Should come on if Starter Switch is bad,,,because You've by-passed the Switch's Contacts and connected the 2 wires together "manually"

TURN KEY OFF BEFORE REMOVING JUMPER WIRE.

You cannot make/break a connection with that much load on it without making a big arc & charring something.

So Be Certain Key is OFF when you install /remove Test Jumper wire

Let us know how it goes.

Good Luck

Answer 2

Here, try something stupidly simple for a change: Disconnect the wires for the a headlamp circuit and *leave* them disconnected overnight or so, maybe longer. I would also recommend removing the top half of the switch to firstly confirm that water got in there and secondly to let it air dry. The water that got in there and is likely shorting the circuit won't ever dry out unless you let air at it. Also run a hairdryer over the suspect components to speed along the drying process (Don't leave it on one place too long or you could melt something, and that ain't good.).
You may be pleasantly surprised to find that patience is indeed a virtue and it sure beats tearing your hair out over something that no amount of troubleshooting will fix. Let me know how it goes for you. And remember that water and electricity don't mix. Next time use a slightly damp rag to run over the electricals on the bike.

Answer 3

I had similar symptoms on my '97 Honda Valkyrie because the starter switch was worn. They get dirty or corrode and the little titts inside can't make good contact. This can cause them to heat and melt. Its fairly common.
Yours might have water in it.
After it drys, turn on the key and wiggle he starter button and see if it will make contact.

Answer 4

It sounds like water got into the switch. This could take several days to dry out. The best thing to do is replace the switch because if water entered once, it will do it again. A simple check is to remove the switch and see if there is water in it. If so, get a new one.

Answer 5

Been a while since I was in electronics, but when you say the wires seem to be ok, I'm assuming you mean visually. To me, sounds like you have a ground somewhere. Try using a multimeter and seeing what your readings are coming up with. I'd say consult either your owners manual or local bike shop for help with readings.

Answer 6

Use a multi meter to check for continuity in corresponding wires,then check the relays and fuses.Most probably water has got to where it should'nt.

Answer 7

It really could be the switch. The water could have fused somthing.

Answer 8

bulbs and fuses sometimes look ok, but in fact are blown....add water to the equation, and Id double check, w/
new ones...........

Answer 9

noone here can trouble shoot your bike, you need to use a volt meter and check the circuit all the way thru.
