Bad voltage rectifier?

[minieggroll]

So when I took the bike for a check up, they informed me that I had a bad voltage rectifier and it was over charging the battery.

I planned on taking it in/fixing it myself but yesterday after riding, the new battery I bought last week's cover popped open and started releasing sulfur gas (smelled like rotten eggs) and was super hot after riding for about 30 min. Now, it will not even start my bike without a jump or push start.

In addition, my headlight burned out 3 days ago most likely due to the voltage issue.

Anyone know how to replace a voltage rectifier or have any advice?

Thanks!

Do you mean voltage regulator?

The voltage regulator/rectifier,is simple to change.Just a couple of bolts.
:cool:

Goggle will help you. Go to Ronayers.com and select the fiche section. Go to electrical stuff for the GZ and you will find where it is mounted and how much money you need.

So easy that even I could do it!
Two bolts, one through a bracket, and disconnect the electrical connections.
Mine went bad, but the 'other' way, it didn't output enough voltage.
Did YOU check it with a meter, yourself?
Check it; buy a meter if you have to - it will pay for itself quickly.
Look around for a decent price on a new rectifier, the prices for a new one run anywhere from about $58 to $177!

Which points should I check to find if the rectifier has gone bad? What readings should I be seeing?

My battery is currently holding a 13.7 volt charge.

I'd expect that, with a rectifier putting out too much voltage.
The easiest way to check is at the battery terminals. According to the manual, with the engine turning over at about 5000 RPM with the high beams on the output voltage should be between 13.5V and 15.0V. If it falls in that range, I would suspect that mechanic of trying to cheat you. Let us know what you find out.

I would venture to say his mechanic is right on the money.With the battery getting hot & boiling & blowing bulbs.
:cool:

Yeah took it to the shop yesterday to get it checked out. They said I was charging at 17 volts. Is that enough to kill a brand new battery in a week's time of riding?

If the battery really did boil over, remove it and check the water content and you may be able to save it if you refill it with distilled water up to the correct level - do not add acid.
Clean off the battery tray if acid spilled all over it otherwise it will remove paint and lead to corrosion of everything under the battery and tray.
