foulkesy Posted January 20, 2010 Report Share Posted January 20, 2010 Finally narrowing down the problem with my Non Working Fan. I have put the fan across a 12v supply and spins fine. I have put a multimeter across the sender switch while in boiling water all OK. I have checked the resistance through the voltage Regulator from yellow to blue and then connecting the 2 blues together simulating the fan switch on, there is a circuit from yellow to black on the fan multi plug withblack and red wires nothing on red, this i believe tells me that this critter is OK or is this not the case?? Now if this is the case, is it the windings on the charge circuit side of the stator? (Bike Runs Fine) If so where can I get it rewound in the UK or the price of new. Patience is a Virtue or so I am told Thanks in advance. Dave Quote Link to comment Share on other sites More sharing options...
pete_scorpa3 Posted January 20, 2010 Report Share Posted January 20, 2010 Give BVM moto at Stroud a call, they may be able to supply a superior aftermarket ignistion set up for your bike or at least point you in the right direction for a repair.

feetdown Posted January 20, 2010 Report Share Posted January 20, 2010 (edited) West Country Windings did me proud when they rewound my stator 80 odd notes 'kin quick turn around too, or a new stator from Lampkins Edited January 20, 2010 by FeetDown Quote Link to comment Share on other sites More sharing options...

I will have to troubleshoot it the same way you did. What is the resistance value of the voltage regulator and the generator. Please let us know what you find and how you resolve the issue.

matt132006 Posted January 21, 2010 Report Share Posted January 21, 2010 hi there im not sure if the beta are the same as gasgas but there a voltage regular ( i not rerly looked on my beta) it sounds to me that yours has gone thanks matt Quote Link to comment Share on other sites More sharing options...
kevc Posted January 21, 2010 Report Share Posted January 21, 2010 I have a 2000 rev 3 and it was the regulator when I had the problem, much cheaper than a rewind Quote Link to comment Share on other sites More sharing options...
foulkesy Posted January 21, 2010 Author Report Share Posted January 21, 2010 I have a 2000 rev 3 and it was the regulator when I had the problem, much cheaper than a rewind Thanks Kev, I have I believe checked the Regulator,correct me if I am wrong(I often am) if I check resistance between the yellow in feed and one of the blue temp sender wires there is a circuit no resistance. Then I connect the 2 blues together simulating the temp sender switching) and check for continuity and resitance between the yellow infeed and the Fan multi connector there is a circuit there between the yellow in feed and the black wire on the fan connector block and it shows around 4 ohms resistance. My next move is to run the bike and check if there is a supply coming from the stator on the yellow wire, any ideas as to what voltages I should se a a few thousand RPM...PS I hope it is the regulator but to me all points to the Stator...any thoughts advice greatly appreciated.

foulkesy Posted January 22, 2010 Author Report Share Posted January 22, 2010 (edited) Ran bike today, checked for voltage from stator yellow feed NIL volts...I think a rewind needed?? Edited January 22, 2010 by foulkesy Quote Link to comment Share on other sites More sharing options...
stork955 Posted January 22, 2010 Report Share Posted January 22, 2010 Gday, sounds like a rewind. Is the Yellow shorted to ground? Cheers, Stork Quote Link to comment Share on other sites More sharing options...
foulkesy Posted January 22, 2010 Author Report Share Posted January 22, 2010 Gday, sounds like a rewind. Is the Yellow shorted to ground?Cheers, Stork Hi Stork, I ran the bike with the Regulator disconnected, put a multimeter on dc connected one side of meter to the yellow lead that goes to the Reg and grounded the other lead from the meter.No volts at all at tickover. I think it should have shown something if ok? I think a rewind, but first get the flywheel off, need a puller, do I need only to remove the centre nut 24mm I think'there are 2 bolts either side of this do I leave these in place ?

stork955 Posted January 23, 2010 Report Share Posted January 23, 2010 Gday, you need to check stator output voltages on the multimeters AC range, not DC. I'd recheck that first before anything else. You should see around 50-100 volts max at say 2000 - 3000 rpm. If thats no good you need a flywheel puller and just remove the centre nut. Impact guns are good for this. Leave all other bolts/screws etc in place, they hold the magnets into the inside of the flywheel. There are aftermarket stators available for these as someone mentioned above, as well as the rewind options. Cheers, Stork Quote Link to comment Share on other sites More sharing options...
feetdown Posted January 23, 2010 Report Share Posted January 23, 2010 (edited) The 2 bolts hold your flywheel weight on, Under that there are 4 crossheads that fix the magnets in place, the weight was an option world wide but standard in the uk, the softer power delivery with it fitted, suits our slippery muddy conditions, I like most of the lads I know run without it and I only bolt it on for extremely slippery days, without it the engine spools up a lot quicker giving more 'Punch' once you got your bike running experiment with & without it, I've had a few electrical problems recently (Last 6 months) I'm sure its just the age of the bike, It is 10 years old after all! and Strongly believe its you regulator I have only heard of triggers failing never the windings on our older stators, 35 odd sods for a VR or 80 odd notes for a rewind, Im sure Lampkins or maybe BVM will send you a VR on return. Flea Bay seems to be the cheapest for flywheel pullers Edited January 23, 2010 by FeetDown Quote Link to comment Share on other sites More sharing options...
foulkesy Posted January 23, 2010 Author Report Share Posted January 23, 2010 Thanks for your replys all, I made the mistake of having the multimeter on DC when checking the feed directly from the Stator, tried it on AC and shows around 100volts + at 2500rpm ish, I am going to try a new regulator .Thanks all Regards Dave Quote Link to comment Share on other sites More sharing options...
