stator overheating

<< < (4/6) > >>

florence:
I have seen modifications where 15A fuses are put inline with the three stator wires as a prevention.  Might help diagnose without burning out another alternator stator.

Bryanj:
15amp way too big per phase, total output of all three not that

Few reports lately where the rotor casing wasn't fitted with the 2 dowels that locate it properly, this caused the casing to sit a little skew and that caused the rotor itself to start to catch on the stator and the field coils. Any sign of rubbing on those? Also make sure the dowels are in place. If they are missing when you look, unless you know they are meant to be there you'd not know they were missing.

This is exactly what happened to mine, you MUST have both dowels fitted.

Hi , please excuse my ignorance, do i have to pull the rotor to check if dowels are in place, where are they located?


Thanks
Brian
