Ah crap...

[p.dath]

I call bullshit, but lets not get into this again

This might be the right advise, but just ignore anything else Dean has to say about GNs... he has some kind of personal issue with them

If the ignition key is off, how could it be the regulator/rectifier?

If the ignition key is off, how could it be the regulator/rectifier?

Guess it isnt then, dont ask me...

My guess would be the same as everyone elses to be honest, worn wires somewhere or a faulty relay..

Just had to point out that the only part of Deans post to take seriously was the advice, not the digging at GNs

It should be a 5amp bulb (Im sure) that you need to replace get a bunch of them from your local shell station or repco, I dont recall you saying the ignition key was off. It answers all the symptoms. Like what i said, pull of the right side cover you should see a white casing you unclip it, there should be 4 fuses going through to the reg/rec. And a 5amp bulb but check it anyway, pull out the battery and behind it you should see the fuse box check (a square casing) everything is right.

Ill post a picture hold up



This is the amp you should replace. I will put in to a song so you can understand it better.

Come on OlieT take of the side cover to get to the devices
You got to replace the reg/rec and it costs great prices
Your not needing to ride around the pacific
Ohhhhh fix your bike. hi ya

So all you got to do is replace the bulb with a new one
It should last you for a few days and give you more throttle fun
Check the fuse box behind the battery
To make sure theres no problems with the fuses, I helped you dont flatter me
Ohhhh makerena hi ya

It IS POSSIBLE a stuffed reg/rect will do this. Simply unplug it and replace the fuse, an reconnect the reg/rect, and you will have your answer.

I think it will be less than $300 though.

Ok, Im stumped and going to bed,

Been unplugging all the relays one by one, then measuring the voltage between the + end of fuse holder (white with black tape i think in your photo Dean) and earth... no matter what was unplugged it always measured 11.92V.

after unplugging and replugging everything, we put a new fuse in and nothing had changed, blew straight away without turning bike on.

Have I been barking up the wrong tree here and testing nothing in particular?

Might have to cancel ferry and visit the mechanics tomorrow instead...

Cheers for everyones help much appreciated!

could be a bit late, but sice you been changing brake fluid, is it possible that you have moved/open the control box that contains the kill switch ? maybe some wires in there are touching (or not).

good luck.

[Ollie.T]

mmm could of... but I don't see how that would short it out when the bike is turned off with the keys... if the short was there, it would only short out when I try to turn the electrics on?

[shafty]

Front or rear brake-light switch? Just a guess...

Yep you been doing it wrong is my guess.

So here's the deal;

If you're blowing the fuse and it's a 15A this means it's a serious current draw. You'd only get this from the positive lead shorting to earth somewhere.

So worn wire is the likely culprit.

If this is happening with the ignition off it means it's either between the battery and the ignition, or anything that is connected through the battery on this side of the ignition switch.

Relays for lights etc that come as standard are usually on the output side of the ignition switch so ignore them.

Any relays fitted for spots or other gear that have been added afterwards and connect direct off the battery could be the problem. Disconnecting those will tell you that leads at the relay aren't touching or the relay isn't the problem.

But leads running to these could be the problem again for shorting out.

1/ ignition off

2/ Disconnect all leads from the battery that are for extras installed afterwards. If there are none then go to 3/

3/ Disconnect the positive lead off the battery and measure the resistance between this lead and earth (or negative on battery). If the reading is low you have a short. Leave the multimeter connected to this and progressivly move your way up the loom moving it around. If you pulled stuff off previously like tank etc near wires check that you hadn't pinched any. Remove whatever you need to remove to track the wire. If you come to any connectors disconnect them to see where the fault sits. You'll find it pretty quickly.

PM me if you want and I'd be happy to be on the phone as you ran through it. This is straight forward electrical diagnosis and shouldn't take long. Hopefully you find it before getting up under the ignition switch.

You're riding a GN250 from Wgtn to Chc?? Yikes!!

You bike's probably actually a transformer and is trying to save you from making such the trip!!

On the other hand, if you managed to fix it and are already there, then well done...

Have not managed to fix it, but am in Christchurch, have work tomorrow you see...

done Christchurch - Wellington and Wellington - New Plymouth before, was not too much of a problem (except for a few hills where I couldn't go much more than 70-80ish...)

Anyway the bike is the the capable hands of the folks at Motormart - will fly back up and ride it down when its fixed. Sigh....

Thanks for everyones help last night and Dean, I have had that damn song stuck in my head all day!!! (flying on pacific blue did not help either...)

Cheers
