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.

Pros: charging problems resolved, starts charging immediately

I will always vote for a 10SI or 12SI GM alternator swap on an L-series engine. Affordable conversion bracket. 1-wire GM alternators are simple, reliable, cheap and readily available online but not easy to find in parts stores. 3 wire GM alternators are are easy enough to wire up and are absolutely everywhere in parts stores if you’re more concerned about parts availability and potential breakdowns on long adventures.

Pros: simple, reliable, cheap, readily available

Cons: 1-wire not easy to find

My shitbox, I replaced my alternator just for my window motor to go bad, I replaced the window motor just for the thermostat to go bad the next day, it’s inevitable.

Cons: Valeo unit mega $$$$$
