Check alternator voltage should be above 14V at 1500 RPM. Bosch alternators are crap anymore, I bought a new WAI global alternator, it has strong output so far. Only time will tell if it holds up.
I installed a Bosch re-manufactured unit. Under $200. It has a 24 month warranty and roadside assistance included.
Aftermarket units from Bosch and other are about $300.
The most expensive one at Rock is a Bosch for $186.79+ core.
A rebuilt Denso is fine and much cheaper. $200 on RockAuto after core refund. Trust me they are perfect to use. You don't need a brand new one from Honda.
A rebuilt Denso brand alternator will be reliable. Denso box or a Honda box is what I trust, no other brands/savings are worth it.
Replaced mine with a denso from rockauto. Unfortunately, the battery light stays on even though the voltage readings are good and have been driving like this for almost a year now.
Even brand name remans like Bosch and denso are suspect but generally much less so.
Broke down and had a mobile mechanic install a no-name Advanced Auto Parts type branded remanufactured one. Ended up failing in 3 months.\n\nHad my trusted mechanic install a Denso remanufactured and have had no issues since.
supplier willing to give me a Bosch remanufactured alternator (as good faith) to compare. after installation on Bosch, the result is worse than the Denso (output at alternator at 12.5V)
