A possible spyder bite

[Queensland Ken]

A mate dropped it into my place last night en route to his home from work.

His bike shows the classic signs of the S6 I think ?

I have bookmarked most of the spyder topics, just a matter of finding them.

Symptoms that he noted:

High beam indicator on, no headlights

Both blinkers on full time, ½ brightness.

No horn

No windshield.

But the bike was able to start and run, so he made a bee line to my place.

So today we removed all what was needed to be removed to gain access to the 8 spyders.

We cleaned up each spyder and couldn't find any corrosion, burnt wires or high resistance connectors.

We soldered pig tails on to each bridging piece and made up a “master” high current loom back to the battery negative, then soldered the pigtails to the loom.

We used conductive grease, much better than dialectic grease to stop corrosion or any high resistance, in the terminal blocks.

Measured the resistance from the furthest connector to the loom tail, less than 0.01 ohms, a short.

Also measured the DC negative current back to the battery and was up to 6 amps with hazards on, horn on, lights on and the windscreen rising, so there is some high resistance on the Yamaha's neutral loom somewhere.

We also cleaned up some of the bikes normal connectors, NO conductive grease used, lol lol.

All up about a 4 hour job.

Just waiting on any news, good or bad to filter through back to me, fingers crossed.

PS Brodies wiring loom on my 07 is much better than the one we made up by far.

Sorry, don't understand what you are trying to say. The current you are measuring sounds reasonable, so what's the problem?

You tied all 8 spiders together? My Grounding Harness only connected 6 of the 8. There are 2 spiders that are part of the electronic black boxes. They are not part of the grounding buss and should remain isolated from the rest. One of them is next to the fuel rail quick disconnect, and has striped wires leading to it. The other one is under the tank heat shield forward and to the right of the bike's headset. It also has striped wires leading to it. If you tied them into the others I strongly urge you to correct that modification - the bike's electronics are at risk that way.

If indeed it turns out to have been number 6 you should file a report with the Aussie version of the NHTSA or Industry Canada - the condition is very unsafe and Yamaha is not stepping up.

Thanks Brodie,

I'll ring my mate soon and tell him.

I should have read your posts better, give us something to do tomorrow, an easy fix.

He made it home all OK after the fix.

Hi BramFrank,

It's one of the first spyder problems I've seen as well as heard of here in Australia.

I'll do a Google search of our Aussie site but I'm sure it's rather rare.

We couldn't actually see any problems with any of the connectors

Another small challenge is that Chris's bike is an ex police bike with a lot of additional wiring, some of which has been removed.

He mentioned that he has had "various symptoms" come and go for a short while leading up to Friday night.

Better go make a phone call.
