Bad Voltage Regulator?

[sjlee]

For the past couple months, I've had a recurring problem. I would go to start my bike, and it wouldn't turn over... like the battery needed charging. Upon inspecting the battery, I would find that the water levels were low, so I would fill it back up and recharge it. The next day I would put the battery back in, and the bike would start fine.

A month would go by, and the same thing would happen again.

I decided to check the battery and VR using a volt meter. With the ignition off, the battery read 12.56V. After starting up the bike and using the choke to get the RPMs to 3k, the battery still only read 12.56V.

My guess is that the VR is shot... am I correct?

If so, I've checked around and found the cheapest price online is $74 including shipping. Is this a good price?

I also checked eBay. There's a used one from a 1996 YZF600 that would work, but I'm not sure if it'll just happen again since it is 12 years old.

BTW, my FZR600 is a 1995, so it has the newer VR with heatsink.

Thanks.

Sounds more like your stator went bad since it isn't charging your battery at all. A bad voltage regulator will usually overcharge your battery.

Have you checked this charging system test out? ---> http://naes.afraid.org/hosting/Diagnosis/charge.jpg

It could be either one, stator or vr that's bad. Check out the charging system test like Mega said before you go buying parts.

Thanks for the replies. How do I go about testing the stator? I saw that flowchart and was able to do the testing of the voltage to the battery, but I'm not sure how to test the rest... like checking the amps between the negatives and the A/C volts on the VR.

Any advice would be greatly appreciated.

The three yellow wires coming from the plug.

This will be easier. Follow this web site diagnostic test by bike.

I think the wires are more white than yellow, but whatever.

Before you go spending 74 on a VR, I think rage is selling one here significantly cheaper (unless it's gone already).
