Alternator OEM Honda or VALEO

the oem has been good for 5 years now

I have a 2001 Honda ST1100 and the bike is a beast. My alternator went out and I had to find a compatible model on ebay because they don't offer the OEM anymore.

Bought a used Valeo alternator, and sure enough, the charging problems went away, and it starts charging as soon as I start the car.

Only use Honda oem denso alternator. Yes they are expensive but you will be replacing it again if you use an off brand. Been there, done that.

He replaced the alternator and serpentine belt. Parts $208 for alternator and belt. Labor $100. Limited lifetime warranty on alternator and 3 years on belt. Honda Civic.

Cheapest for me was a new Valeo unit from Rockauto. Cheaper than Turner too.

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 a 2013 manual. I've had to put 3 or 4 alternators in mine. The last one literally lasted a year, luckily it was still under warranty, and I only had to pay for the labor to have it changed out.

I have a 2002 acura el 1.7... battery lite in. Have put 3 aftermarket alternators in it, a new battery. Replaced all grounds, now replaced the ecm. Battery lite still on and car won't charge.

I've had bad luck with aftermarket alternators. Whether I put them on due to customer request, due to price difference or had them come in with issues. Sometimes not charging while still new, or relatively new. Sometimes the charging light on even though it's charging properly.
