Urgent help needed - RF900 voltage regulator

[riffer]

Isn't it the same one as one the GSXR1100? That would be easier to find.

Well got it all back together and seems to be running fine. With high revs voltage only goes as high as 14.5V so all good.

Full test will be once a new battery is installed and bike taken on a decent run.

If anyone encounters a similar problem give me a yell.

Cheers all.

Well well well,

I have managed to fix the voltage regulation problem but now the rev counter wont read above 500rpm.

Any ideas?

Hopefully its not the ignitor unit as they are around $US400.

Will keep you posted.

Hi all

Well I now have everything going on the bike.

Found out the problem with the rev counter was a cooked resistor. Replaced this and all is fine.

I now have intimate knowledge of most of the electrical system on an RF.

For those that are not aware, if your volage regulator craps it self it can casue quite a bit of damage to other electrical components due to overvoltage.

A bike shop can source you an aftermarket one from 2 Wheel Wholesale. We put one in an RF900 just last month. If you're mechanically minded you can install it yourself as it's inside the alternator. Price .... somewhere around $150 (that's a guess not a quote).

Hey there..

Where did you send your rev counter to get fixed???

I had a major electrical meltdown a year ago.. shit the CDI unit, regulator, battery, temp gague, petrol gague & rev counter.. all the bulbs etc. Cost me ferkin $900 to get her back on the road, with 2nd hand bits! & all the dials still haven't been fixed yet either!

Seems it is quite a well known problem with the gsxf's.. over charging.

Suzukis from the days of the GS series have been renowned for crap charging systems. The GS Resources site has a number of pages devoted to fault finding and repairing http://www.thegsresources.com/garage/gs_statorfacts.htm

I am lucky enought to have an electrical trade so fixed all the problems myself wih a little help from my friendly local auto sparkie

With most gagues it is the diodes inside then that die. Once you manage to pry the gagues open and find the stuffed one, replace it they seem to go again.

Mine did have an IC it it so I guess the newer bikes will be the same.
