Did you check the bulbs to see if they were actually burned out?

Yup,the headlight bulb is completely fried (both the low beam element and the high beam "spoon" thing) even some pieces floating around inside the bulb,the tail light has the "running light" filament burned up but the other filament,the one that lights up when you hit the brakes is completely intact...but those lights don't come on when I press the brake levers so theres been no current applied to it. I think that is tied into whatever issue I seem to be having.

I've got the battery on the charger right now,I was getting very low voltage on it so once I get it charged up I plan on testing the voltage across the battery again.

If your battery is going bad but you keep blowing bulbs, you have a short. Set your meter on continuity and start checking your power wires. When it beeps you will have found the wire that is shorted. Then you just have to figure out where it shorts at.

I think I may have a cooked battery. I've had it on my Tender for about 5 hours now and it will not reach a full charge. Took the Tender off,read the voltage at 8.5v but it's not constant i.e. the voltage decays very quickly....within seconds the voltage drops from 8.5 to 6v and keeps going down. I would think the fuse there would prevent that but is it possible a loose ground at the stator would ruin a battery?

[Guitarman]

Yep. Your battery is toast. How much voltage is coming out of the stator? If it's overcharging, then that's a problem. It should be somewhere around 13-14.5 volts. It might get as high as 15v but that's on the very high side.

[Alleyoop]

The Stator feeds AC Voltage to the Regulator/Rectifier it in turn Regulates and Converts it to DC Voltage to charge the battery. So you can test the STATOR to see if it is feeding the R/R good AC Voltage anywhere from 40-100 ACVs if so then the Culprit is the R/R.

To see if the charging system is charging start the motor and hook up the Volt meter to the battery and rev it up to around 4K and see if it is putting out enough voltage usually 13+. If it is your problem is just a bad battery.

Yeah, what he said. LOL
If this was a motherboard in a server, I'd be all set. Still have to learn all the base voltages for scooters.

[Alleyoop]

Just remember STATORS all put out AC Voltage never DC voltage. When someone says I have a DC system all that means is the CDI is DC and it is fed from the BATTERY Through the Ignition Switch when you turn it to on. The Battery always is feeding the IGNITION 12V going through a fuse on the little Red Wire coming off the Battery. Then when you turn the KEY on it feeds the rest of the system Some feed a FUSE box which in turn then feeds the other parts of the system.

I may have been wrong about the battery,maybe a little impatient. I left it on the charger overnight and this morning when I put the meter on it....11.9v, though it does seem to be bleeding a little bit as I checked it again about 5 minutes ago and it was at 11.7v...but I think this battery is slowly on it's way out. I'm gonna have to wait until the weekend to check everything on the stator as apparently my professors think Halloween week is the perfect time to bog us down with exams (I've got three this week). So I'll have to wait until friday after my test to really get in there and start digging around. I'll let yall know what I find....but I do have another question....what would cause a stator to overcharge???

[illwill420]

Hmmm now even more oddities....put the recharged battery in,now my brake lights and turn signals work!! So now this question becomes...if a battery is going bad would it simply short out and send all the voltage to the headlight thus blowing it? Am I even asking this question right??

I still plan on testing the voltage this weekend on everything but for now,very happy that people will know when I'm stopping and/or turning.

[Alleyoop]

BRO, you have a bad battery, if you had it on charge overnight and it only read 11.9V that is a bad battery. A GOOD battery should read 12.5-12.7 volts, Buy a new battery and quick fooling around.

[illwill420]

Yeah I kinda figured as much,but...would that cause the front headlight to blow and the tail light to blow a filament??

[Alleyoop]

Yes, because the R/R is trying to charge the battery with to much juice and what it does is it shunts the overage to ground and will blow out the bulbs.

Ahhh now it's all making sense! Learn something new everyday huh? Thanks for the help guys.

Update:

Sorry it's been a while, got caught up with classes. I have finally dug my way out of the pile of books. Anyhow, I replaced the battery and all the bulbs, still had the same issue. Battery wasn't charging, blown bulbs, you name it.

I came across another thread that had mentioned that sometimes the r/r you order has the two top poles switched. Well, I got a wiring diagram of what the r/r/ was supposed to be, then checked voltages at the wires running into it. Low and behold the top two poles had indeed been switched,so...with a bit of clever rewiring, I switched the top two wires going into the connector to the r/r and now she works like a charm. Battery is staying charged and getting a return charge, lights are working, and it almost seems like the scooter is even running better.

So, long story short...check those new r/r's. Sometimes the poles are swapped and can cause a multitude of headaches. Thanks for all the input guys.

i think you hit it on the head alley ,,,it sounds like too much power ,,i'd be changing the regulator/rectifier,,,
