I know this has been done to death but im a little stuck, 2006 Blade, rode to work no issues. Leaving work it cranked a little longer than normal but then fired and rode home. At home, turned it off, tried the starter again out of curiousity, no juice. Jump it, fires fine, when running it showing 11.5v across the battery and falling. Fully charged the battery, bike fires fine but still falling voltage at the terminals, So... Checked the diode readings of the reg/rec - all fine. Checked the Voltage out the phases of the stator - all fine. 15v on tickover rising to 45 ish at 4k rpm. Anything else to check??
This is the best test I know, If not the charging system ... Battery. Charging System Test. 1) Make sure the battery is fully charged, and tests OK. Take it to your local batteries place and have it discharge tested. After charging a bad cell in a battery can give you 12 volts, but fail under load. When in doubt, replace it. 2) Start the bike. Take your electrical meter set to DC volts and measure across the terminals on the battery. With the bike running it should be somewhere between 12 and 13 volts at idle. 3) Rev the engine, and measure the voltage at 4000 - 5000 RPM. It should climb to 13.9-15 V. If it goes over 15V, your regulator rectifier is cooking the battery. Replace it. If it doesn't climb, it's either your stator or your RR; you'll have to follow the Stator Testing Procedure below to determine which it is. Stator Testing Procedure This is probably the easiest, most reliable test: Always start charging system tests with a fully charged battery. 1) The stator will have 3 wires coming out of it. Usually they're Yellow. Locate where they connect to the Regulator/Rectifier, and disconnect it. 2) Start the bike. 3) Take an electrical meter, set it to AC Volts. Measure voltage between any 2 of the wires. You should get 15+ volts across them at idle, and when you rev up the bike, it should quickly climb to anywhere from 40 to 80 volts. 4) Check all possible combinations. If you don't get voltage, or get low/ none, the stator is bad. Every other test you can do (continuity to ground, resistance between the pins, etc.) won't answer the question: Am I getting output from the stator? If you're getting output from the stator, and the connectors look good, your Regulator/Rectifier is most likely unwell.
Sorry to jump on your thread, but I'm having issues as well. Have done all the usual tests except the one above. I will do the above test tomorrow as I didn't have time today. I was told that the ground test(ohms setting on meter, negative to battery, positive to each pin) should give you no reading, I get a reading on every pin!!! Should I assume it's the stator? or still do the above test? I found a RR+stator set on E-Bay if I need to replace reasonable price, should I be worried about quality. Feedback score good. http://www.ebay.co.uk/itm/Alternato...538516?hash=item56816c3014:g:ADcAAOSwB4NWzD-m Many thanks
I have tested stator as you described and it's knackered giving 9v on two coils and 3.4v on the other even at 5000 rpm. So it's new stator time, still not sure if I should go for the E-bay deal, or just the stator. Cheers
If I had the money I'd change them both. But that's me, I tend to have the thought process.... if I'm broken down on the A189 in the wind rain and dark, sick as a chip, I will be kicking myself about the extra few quid I didn't spend.
Yeah I was told it's best to change both, because it's usually a dodgy reg/rec than blows the stator. Not sure if that is the case or just a ploy to get more money, but the e-bay deal is good value. Cheers for your input.
Im still struggling with mine - fault appears to be intermittent! Rechecked it all tonight: Stator phases show 15V 17V 17V on idle - rises with revs. Reg shows 1 1 1 650 670 670 1 1 1 650 660 675 With the bike idling im at 12.5 v across the battery, measuring what comes out the reg, its 12.5v although every now and then it drops randomly to 4, or 7 v and then back up. Im assuming the reg should give a stable 13/14V so im assuming this is the culprit.
Worth checking all wiring and connections, especially the grounds/neg. Is any of the wiring getting warm?
Yeah i went through the wiring, good earths where needed, continuity down the neg/positive leads to battery, checked the fuses etc. Nothing getting warm, just seems a little rattlier than normal so might pull the stator anyway.
Pulled the stator out last night and one coil is burnt up, guessing i caught it early as it was still showing voltage, but was dumping some of it to earth. Typically its been nice weather this week
Think my woes continue...fitted the new stator tonight, from electrosports. Charged battery, she fires up and immediately sounds happier. At the battery: Cold start fast idle - 14.9V Warm idle - 13.9V Warm idle with main beam - 13.1V Warm blip the throttle to 4k rpm - 15 odd V. (headlights noticeably brighten). So i guess my reg/rec is screwed too. What i dont understand is why all my electrics pass the tests, but are fecked.
Bummer, what procedure did you use to check the reg/rec? did you check positive and negative sides, on all 3 pins, So you get 12 readings?I know it's not a blade reg/rec but same procedure. I watched this vid
Yeah, so mine read cold last night: 1 1 1 573 575 570 580 581 583 1 1 1 So resistances are in spec. Some articles on the web suggest 13 - 15.5 V charging is normal, but i always thought anything over 15 is too high.
