Hi folks,
Looking for a wee bit of help with my 2000 Sv650. The bike had sat for two years so when I got it she was serviced and I replaced the battery with a new one. Unfortunately she's a pain in the arse at the mo. I rode it about 60 miles with the new battery, lights on and no issues. Stopp for a while and then rode another 30 miles to a mates place. Then she wouldn't start, multimeter put the new battery at 12.2 volts (then bumped) and as I revved it the multimeter showed the voltage going down as the bike revved not your usual up or steady voltage count. rode it home with the lights off but due to worsening weather I had to turn them on, when I used the indicator the needles on the clocks dropped.

I have ordered a new regulator and believe that the 1st gen sv were known for having faulty ones. My question is because the r/r may have gone will this also have caused the stator/alternator to become faulty as I have seen suggested in some threads. Is there a way to check the reliability of my stator? I have a multimeter but wouldn't be too au fait with checking ohms etc.

I just don't want to have got a new battery, new r/r and then have to replace the stator and perhaps the r/r again as the stator has overcooked it .

A wee bit of advice would be most welcome!

Cheers!

Welcome aboard!

I wish I could offer some solid advice, but I have not encountered this yet(knock on wood) with my bike. I wish you the best of luck getting this resolved ASAP, and I'm sure someone on here will have a better answer for you!

You would need to worry about the stator if the R/R overcharged the battery. In your case it seems that the R/R was undercharging the battery. I will post the page from the Suzuki service manual for you to test the stator output. Make sure that the connectors from the stator to the R/R and from the R/R to the harness are free of corrosion as well as your battery cables. A fully charged battery should read 12.5-13VDC at rest. At idle, the voltage should be at least in the high 13s. At 5Krpm, the voltage should be 13.5-15V.

ya overcharging is no good, I fried my cdi, and guages on the track

kinda simple, but make sure you don't have bunch of extra electrical add-ons. My first bike (FZR600), some had "ugpraded" the headlights from 35w to 100w before i bought the bike. That extra 130w (two headlights) put a big drain on the system and melted the headlight plugs!
