Installed #2 alt. last weekend and so far it's been good/consistent. I've been researching similar symptoms, watching YouTube how to test an alt. , and also bought a battery tester/analyzer for peace of mind. I'll have to keep an eye on the rpm's, its my wife's daily so I don't get a lot of feedback unless it dies. I don't think it was over charging, cold start around 14V is spec and then drops as I turn on additional loads and keeps up with demand at high 12V-13V. Both +/- cables are clean including the ground.I've been having similar struggles. Replaced the stock alternator with a Denso reman on my 01 LX with 175k. Now it wants to idle around 500rpms which I guess is too low for the alternator to charge. If I bump the throttle up to 700 it starts charging but isn't as strong as my stock alternator which usually ran in the mid 14s under load. But now reading this post it looks like maybe my stock alternator was overcharging? I replaced my positive battery cable connection and today I'm going to do the negative cable connection as I found after cleaning it became loose. Hope you get yours straightened out!
