How do I test my tiger cubs stator to find out if it's putting out a charge?
Answers:
This was always a problem on the cub because the cable runs so close to the primary chain. normally a worn chain chops the cables.. it's easy, there are three cables and you need to see a voltage between any two.. test each pair in every configuration, if one cable isn't playing then try them one at a time, voltage to chassis.. Engine running of course.
Always give year, make, engine size and model # when asking questions.
The stator windings can be checked with an ohmmeter to see if it is either open (very high resistance) or shorted (zero resistance). The stator gets energized by the battery. The stator is the stationary part of an electric motor. Depending on the configuration of the motor the stator may act as the field magnet, interacting with the armature to create motion. The stator may be either a permagnet or an electromagnet. Electromagnetic stators are used in wound field DC motors.
The non-stationary part on an electric motor is the rotor.
Welcome to the mysteries of LUCAS electrics
Its a permanent magnet system. the magnets go weak and the wiring harness (where it goes through the primary chaincase) gets worn through. I think a BSA C15 one will fit and it may be easier to get hold of (I aint worked on this stuff for at least 35yrs) You need to check continuity between any two of the the 3 output leads (or is yours 2 wire?) should have continuity and be open circuit to earth (ground) Battery is POSATIVE earth, not negative like japanese bikes, if you connected it backwards rectifier is probably fried (not a big deal though,can always fit a jap one and go NEG or a new 'genuine' one and stay POS) join TOC, about 20 quid a year they will have all the info you need
