haven't been on here for a while but just curious if anyone else has ever had a alternator failure issue? I have burned out 3 reman altenators in the past year,, checked my air heaters and working fine, not staying on.. batteries load tested several times, all ok.. all connections and grounds cleaned.. 2 alternators from orileys and 1 bosch.. not sure whats goin on here?

 

Most reman or exchange alternators available today are junk. If you bought a Bosch the third time is it an actual Bosch or a chinese knock off? Why did you replace the Bosch unit with?
