I have a 2007 Vee that a buddy and I just did some maint. on . We set valves , flushed coolant, synced T/Bs. We put it back together and I noticed at idle my volt dummy light was flickering red. Idle is 1250rpm and all electrical connections that were unplugged are plugged and secured. I've put about 350 miles on it and it seems to run great but now it has a solid red light at idle. My thought is it could be the original battery finally going bad. It turns over freely and fuel pump bu
ilds quickly .It fires right up. I just don't want to walk out some day to a dead battery. Any suggestions ?

Hi, I'm back. I just installed a new OEM stator. I thought it went quite easy until I took the NO LOAD reading and all three contacts read 67-68 volts. I used two different R/R's and only have 12.8 at the batt. The service manual says (more than 75V at 5000rpm hi beams on engine cold)and 14-15.5at batt. Looking for answers

I guess what I would do in that situation is to break out my DVM, but any digital or analog would do, and measure the voltage directly across the battery during idle, ( 13.8 to 14.2 ) and before start with all switches off position. ( 12 or close to) And compare to that seen on the terminals of your "volt dummy light" and look at the documentation for the volt dummy thing ya got there and see if it's working as advertised. This actual data could also give ya an idea how your battery / charging system is doing as well.

Are you getting an FI at the clock position or are all the temperature bars full. If not, it's an oil pressure warning light. It would be a good idea to check the oil pressure. It should always be between 14 and 57psi. If it's okay, the sender is suspect.

Thanks StromWee I'll try that. I'll test the batt. also. Grey Wolf I think you may have missunderstood .This is an add on light. There are no codes coming up on the guage cluster, they all seem normal.

So it's a voltage level add on light. Checking the actual voltage with a meter would be the first thing then. For better voltage at idle if everything is working, a MOSFET regulator/rectifier is the best bet.

Well, the first question is what's the light connected to? Until we know that, we're just guessing... It could be connected to a whole bunch of different things...

Yes, go with your instinct on this and replace your battery. Its 4 years old and you state that the battery volt dummy light is now red indicating a low voltage condition. Throw a new battery in there, clean up the connections and make sure they are tight. Peace of mind is now yours.

Charged battery over night and had it checked at Advanced Auto . The good news is ; the battery is good . The bad news is ; the battery is good !

Go back and get a volt meter. See what kind of charging voltage is present and bear in mind that 12.2-12.4 volts at the battery is actually a pretty dead battery. You should see around 12.8v at full charge. Charging voltage should be at least 13.5-14.2 as stated above.

Idle speed should be around 1300. Doesn't seem like that would be a problem, but you never know. If you did the TB synch without the SDS tool to monitor rpms that may be why you are a little low. Are you reading rpms from the tach or an external gauge?

All you have to do to check it for a low rpm condition is goose the throttle just a tiny bit to see if the voltmeter light goes off.

Did you get a new meter? If not, get one. If so, what readings do you get with the meter attached to the battery at idle and at 3000rpm? If the idle is below 1100rpm warm, adjust it up to 1100-1200rpm.

Brand new meter plus my buddy's meter.Also checked it against his 02 D1K.
started with bike off batt. was13.14volts . at 5000rpm 12.8volts ,at 3000rpm 12.3volts

The stator may be new, but it's below spec.
