Had the same in reverse. Bosch factory, Valeo worked fine though.
Remember the old Bosch and Valeo alternators where the brushes were built into the regulator, which cost $15 and came off the back with two screws? Pepperidge Farm remembers.
Bought a used Valeo alternator, and sure enough, the charging problems went away, and it starts charging as soon as I start the car.
I would go for the Pure Energy new Mistubishi that is 190amps for 200 bucks.
Cheapest for me was a new Valeo unit from Rockauto. Cheaper than Turner too.
I had Valeo in my other car, very common for Bosche to overcharge.
I did see something recently where an aftermarket alternator made by Valeo had the same part number as the Original Toyota part, but in fact had another software part number that made it through an error and not work properly.
I have one with 44k miles sitting in the garage right now with a bad TPS and an oil leak.
The last drive down the street saw me with a dead alternator and blown alternator fuse. Replacing those two resulted in the above surprises afterwards.
Even replacing the alternator is a half day knuckle busting job assuming you know what you are doing.
Mesmo um Valeo novo está caríssimo, pede mais orçamentos.
Also today, need naman bilhan ng alternator which is 40k yung genuine parts kasi nag oovercharge yung battery and other things pa na di ko pa alam kung anong sira yung lalabas pa.
