[QUOTE="Fred W, post: 1307681, member: 3828"] I recall that those who have autopsied starters from FJRs after it went tits up have found that the permanent magnets that make up the stator half of the motor had come un-bonded (unglued) from the motor body and then shifted circumferentially out of position around inside the motor. This resulted in the reduced motor torque per watt of input power to the rotor, and excessive current draw. I recall some have cleaned the armature commutator, rebonded the magnets in place, and the motor was good to go. Of course, not wanting to have to dig into the FJR bowels that far again, many have just sucked it up and installed a new starter motor. Boy, wouldn't it be great to have a current reading?
