October 20, 201213 yr This engine came along with a recent purchase, is there any chance the stator could have survived ? Thanks Ross
October 20, 201213 yr 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
October 20, 201213 yr Author Thanks Ian, would put a new condersor up by the coil, any idea what the coil resistance should be ?
October 20, 201213 yr 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, 201213 yr by grib
October 21, 201213 yr Author 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
October 21, 201213 yr 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
October 23, 201213 yr Author Thanks Gordon Will give it a go when I an get one of the meter's with a needle. Ross
