bigbird2 Posted January 29, 2022 Report Share Posted January 29, 2022 My bike would not start (after previously starting easily and running fine) and I've spent many hours trying to figure out why. It had a spark but it was weak! Section 3.10.1 "Testing the Ignition Stator" in the official Beta Workshop Manual says: The stator winding must be inspected while the temperature of the component is ap- proximately 20 °C. The inspection may also be performed with the generator coupled to the engine. Disconnect the 12-way black connector between the generator and CDI and with the use of a multimeter, verify that the resi- stances read between the terminals shown below fall within the prescribed range: black-white (pick-up): 320 ohm ± 15% red-blue (condenser): 300 ohm ±15 %yellow-brown (services): 0.45 ohm ±20 % I got the prescribed values for the "black-white" and the "red-blue" terminals but there is NO YELLOW terminal so nothing to test for the "yellow-brown (services)??? There is a yellow wire near by but it does not go thru the 12-way connector?? (and it does not give the 0.45 ohm value when tested with the brown wire that is in the 12-way connector Does anyone know what the disconnect is??? I also have been unable to find a Wiring Diagram that is applicable for this bike. Can anyone point me to one. THANK YOU for any help!

Have you pulled off the flywheel, cleaned the rotor, checked all wirs inside and made sure you did not shear the flywheel key? Next thing would check all grounds, including the screws that hold the stator on. Quote Link to comment Share on other sites More sharing options...
greychapel Posted January 29, 2022 Report Share Posted January 29, 2022 May not be relevant but worth checking, had similar problems with my Evo, when i took the trigger/ pick up coil off to check the stator there was a lump of dirt/ grease on it, i cleaned off with solvent and lo and behold everything was fine again Quote Link to comment Share on other sites More sharing options...
bigbird2 Posted January 29, 2022 Author Report Share Posted January 29, 2022 Thanks folks, I did take off the flywheel and cleaned up in there and checked all the wires before I made the first post above. It did finally start but the spark is still weak and it sometimes takes several kicks??? I would still like the answers to my 2 questions: Disconnect the 12-way black connector between the generator and CDI and with the use of a multimeter, verify that the resi- stances read between the terminals shown below fall within the prescribed range: black-white (pick-up): 320 ohm ± 15% red-blue (condenser): 300 ohm ±15 %yellow-brown (services): 0.45 ohm ±20 % I got the prescribed values for the "black-white" and the "red-blue" terminals but there is NO YELLOW terminal so nothing to test for the "yellow-brown (services)??? There is a yellow wire near by but it does not go thru the 12-way connector?? (and it does not give the 0.45 ohm value when tested with the brown wire that is in the 12-way connector Question #1 - Does anyone know what the disconnect is regarding the yellow wire??? Question #2 - I also have been unable to find a Wiring Diagram that is applicable for this bike. Can anyone point me to one. THANK YOU for any help!

lineaway Posted January 30, 2022 Report Share Posted January 30, 2022 Did you remove the spark plug cap and trim back the plug wire till you had clean wire again? 1 Quote Link to comment Share on other sites More sharing options...
