gn250 fuse keeps blowing

[baddeley]

Hey everyone, new the the forums, new to motorcycles
I got given a 2007 gn250, it had been off the road for 5 years now. I managed to push it home, change the gas and put a new spark plug in and she started first pop with a jumpstart (dome 17km a with no problems). I went out to go out the following day, so I let the bike warm after about 5 minutes it turned itself off. No chugging no nothing it just died, I checked the fuse (only fuse I've been able to find) and it was blown thinking it was an easy fix I went and got a new fuse connected it but before I could even put it in properly it had already blown. I've tried unplugging all the wires and reconnecting a new fuse but same thing happens. Can't see any damages wires either. This is driving me insane, I've been having so much fun on the bike (never ridden one before this) and I just want to get going again. Any help would be greatly appreciated, thanks in advance

I think I have found the problem, I've fully disconnected another thing and now I can get power to the bike and even turn it on. Everything runs fine without this item plugged in, can someone please tell me what it is and what it does and weather or not I need to replace it asap or if it can wait a little bit.

I have a short penis. I can't find it and fix it.

There ... fixed it for you ..

looks like a rectifier. It charges your battery.

It's a hoo-dacky ... and essential for every motorcycle ....

Its the rectifier/regulator, bike should run without it but won't charge the battery. The three yellow wires come from the alternator, if you have a multimeter it would pay to check if any of them are shorted to ground, but more likely the unit itself as a faulty alternator wouldn't usually cause the battery fuse to blow, would show as a short from the output wire to the case

Awesome! Thanks heaps!!
I got a new battery, it wouldn't damage it without it equipped? And so this is all I need? http://m.ebay.com/itm/281312284189?nav=SEARCH
Just looking at ebay and the prices range from $20-$130 this shouldn't make a difference in the quality?? They both look the same to me :/ thanks for the help again, so happy I can hope back on the bike again, hopefully I'll get further then 17km before the next problem rises haha

Forgot to mention I don't have a volt metre, is there any other way to test it? Took me a good 12 fuses to find the problem in the first place

rectifiers simply change power from AC to DC, the alternator charges your battery, and the regulator monitors the rate of charge

don't waster fuses, use a circuit breaker or a bulb in series with a fuse to limit the overlaod while tracing the fault

not strictly true. Then. Neither was what i said.

op, go and buy a multimeter and learn to use it.

Second the multimeter.
$20 will get you one that does the job. Nothing bites more than paying $100 to wait 2 -3 weeks for the wrong part.

Someone correct me if I am wrong: The same condition could be caused by the stator having a short but the loop opened by having the reg/rec disconnected.

As to do $20 reg/rec work the same as $120 ones?
If they are the same brand and model yes. If they are different models their could be a difference in materials (more a durability risk than function risk) or the more expensive one may be more expensive because of branding.
A higher durability after market one for my bike would cost me less than oem, but only by half.
