b40rt Posted October 20, 2012 Report Share Posted October 20, 2012 This engine came along with a recent purchase, is there any chance the stator could have survived ? Thanks Ross Quote Link to comment Share on other sites More sharing options...
naichuff Posted October 20, 2012 Report Share Posted October 20, 2012 From the photo it does not look that bad If the coil resistance are good then ok do not know about that the condencer bit iffy Not so sure with alloy back plate depends on the corrosion on it. It may clean up as with the flywheel Quote Link to comment Share on other sites More sharing options...
b40rt Posted October 20, 2012 Author Report Share Posted October 20, 2012 Thanks Ian, would put a new condersor up by the coil, any idea what the coil resistance should be ? Quote Link to comment Share on other sites More sharing options...
grib Posted October 20, 2012 Report Share Posted October 20, 2012 (edited) It might be OK this one works now, I did have to replace the trigger coil as it had rotted through, stator was OK though. Edited October 20, 2012 by grib Quote Link to comment Share on other sites More sharing options...

b40rt Posted October 21, 2012 Author Report Share Posted October 21, 2012 Has the flywheel lost a magnet? Hi Gordon All four are still there and it still has magnetism (if there's such a word) Ross Quote Link to comment Share on other sites More sharing options...
gii Posted October 21, 2012 Report Share Posted October 21, 2012 Yes, it's a word, more correctly magnetic flux density, measured in Gauss or Tesla. Anyway, since the flywheel is intact, I'd have thought you could test the 2 coils independently. The Condenser is well below the tide mark so I guess its had it. I can't see from your pics how the coils are wired, but there will either be 1 wire coming from a grounded coil or 2 wires from a non grounded coil, possibly you have one of each, 2 wires from the generator coil and one from the trigger coil I would isolate the coils and lead the output wire(s) through the back of the casing and connect them to a multimeter, a cheap old fashioned one with a proper moving needle not a digital one. Then I would remove the woodruff key from the crank, oil the taper and spin the flywheel by hand on the taper, looking for a kick from the meter needle. If you've done everything right and you don't get a kick reverse the connections and try again, if you still don't get a flicker then looks like a new coil, if the meter needle is wrapped around the stop, then things look brighter. I'm sure on the old site there was a forum link by someone who had found a supplier of cheap stator coils available from stock in all sorts of dimensions but I can't find it now. They were intended for the myriad of scooters that have been available recently as pattern parts and I think he'd matched one to his Beta Quote Link to comment Share on other sites More sharing options...
b40rt Posted October 23, 2012 Author Report Share Posted October 23, 2012 Thanks Gordon Will give it a go when I an get one of the meter's with a needle. Ross Quote Link to comment Share on other sites More sharing options...
