Electrical fault? Help!!

[MikeyC]

Was riding on the motorway last night, had a quick glance down at my dials... was doing around 80 (honest officer!), but then as I looked down, the needles on both the rev counter and speedo just dropped, but the power wasnt affected? I f**king sh*t myself at the time though!

Since then, when I rode it again last night and even this morning, the needles are fluctuating.. one minute working fine, the next minute not working.... but at the same time the needles move, the headlight flickers on and off? So now not only are my needles playing up, as far as other road users are concerned, i'm flashing them! lol!

The bike has just had a big service, new battery is in place, so I might take it back to the garage that did the work, see if they can sort this out. Hopefully its a 2 minute job and easy to fix, but anyone any ideas as to what is causing this? Thanks!

Most probably a lose connector somewhere in the front of the bike.

What age is your bike? I had a similar problem on mine, kept losing the speedo, when I twisted the accelerator. Found it was the speedo sensor that was the problem, replaced it not had a problem since.

Yes, I would remove the fuel tank and look underneath there because you'll no doubt find the wiring looms connection blocks to the front of the bike which probably haven't been cleaned out with WD40 since day one. So disconnect/reconnect them and spray the connections thoroughly with WD40 even where the wires go into the back of the connection block too to remove the possibility oil or build of crap from the road that has no doubt built up in them.

Ok, will give this a bash! This wouldnt have been triggered off by the garage when they stripped and serviced the bike though would it?

Mike, could just be a dodgy earth, check the neg terminal on the battery is tight.

Mines the 1999 'SRAD' model, no idea where the sensor is!

[sychosis]

It's the same then, have a look later or when you get chance, it's a small type block sticking out near the top of the clutch housing!

If you take the left hand faring off, you should find all the connector blocks.
