help with no power to gpz 1990

[Guest]

had been sat for 2 years, rode it home and it overheated and not been able to start her up since.

i think the engine is still good, ive stripped and cleaned carbs, bought a new battery, but i have zero power to the bike (lights, neautral light, indicators)

tried jump starting with car, tried push bump starting....nothing, nada.

i have a blown 20amp fuse, could that be the reason for their being no power for the bike to turn over...is it an important fuse.

i also thought i might have blown the main fuse (50amp) but have spent around 2 hours trying to find it to no avail.

help appreciated.

p.s. i bought some 20amp fuses (20mm) but they were too small....should i get 30mm?

I had a GPZ500 so it may not be quite the same but...

There was one fuse box which was next to the battery. All fuses are important! If you have a haynes manual that is your best bet to understand the electronic workings of your bike. If you got your google wizardry on i'm sure you might be able to find the wiring schematics.

And yes change that fuse with one that fits. The main thing is having the ampage correct, if it kinda fits but is in place nice and tight i wouldn't worry too much.

so for my original question, without that 20 amp fuse, there will be no power to the whole bike?

thats what im hoping, as its a simple thing to sort out.

I have never known a 50 amp fuse on a bike! 20 or 30 yes

First thing is to change that blown fuse and get back to us

yeh there is 50amp fuse, but not in the main fuse box, its a green plastic one with 2 prongs like cars have

or atleast thats what ive been told.

im finding it tricky to locate, if like you say.... it even exists at all

Like I say I have never known it that doesn't mean it doesn't happen

If there Is a 50 amp fuse it will be on the starter relay follow the main positive battery cable it should lead to it

the gpz was never the best bike to start with im sorry to say but as stu says ive never known a 50 amp fuse on them 20 amp in the side of the starter solinoid very often thats about as big as they need to be and that will be a balde fuse like a car very often

is it the fuse just above the coil? if thats the fuse you on about if its anything like the gpz500 it should be 30 amp and you may need new coil, it is a common problem with the gpz for the coil to go on them, if it blows fuses and lights that sign that coil gone
