mine did so afterm 80 hrs

check the armature and bolts around the case if you feel any slack the interior is ready to disintegrate

the bolts holding the outer case need to be torqued 10 hrs after new installation

easy to check

Subject: [LML] Alternator Failure Question

This is probably a question for my mechanic, but can alternators start failing after 180 hours on IO-550’s? Is failure typically intermittent?

(I am getting intermittent drop-offs in the Amps reading on my engine monitor – down to single digits and then negative amps in the teens and then the system restores to normal after 1-2 minutes.)
