Ahh I'm going crazy '89 GSXR-250R

[mister.koz]

Just checked the resistance of the coils, read somewhere it should be 3-4 ohms. I've got 10 ohms on one coil and an open circuit across the primary of the other one so i might be onto something. I pulled out the CDI and found it's been previously repaired / tinkered with. (held together with silicone gasket goo) but yeah, i brought some new coils today so i'll see how that goes.


Oh and does anyone know where the rectifier is on my bike. I think it's the thing just aft of the cdi thats looks like a magnesium type box with a massive heatsink on it.

Sweet, that sounds like the rectifier man.

Odd that the coils died?? But weirder things have happened.

Yip that will be it.

ok so a box of gsxr bits arrived today (thanks Pumba) so i changed out the coils, (after re-checking my original ones they actually seem ok) nothing changed, still wont start. I went to change the rectifier but my new one has an extra wire on it. My old one has 3 yellows from the alternator, and another plug with a red and a black. the new one has another wire in the red & black plug.

Also the CDI is the wrong one unfortunately so i can't check that.

I tried disconnecting the output of the rectifier and starting it that way but still nothing,

If i biff my multimeter into the output of the CDI i can see the voltage bouncing up and down so that seems ok.

Does anyone have a wiring diagram for this piece of sh!t because im going a bit mental.

Cheers

I got 30gb of bike manuals stored at work, will check it out tomorrow dude. Drop you a PM if i find it.

Ahhh stink man, if none of that stuff works package it up and send it back and ill flick your money back through. Possibly the difference between the 88-89 models.
