So, earlier this year I replaced my alternator and diode from the Z store ( 240z Alternator Upgrade with internal voltage regulator)

I have been driving it on and off all summer and fall. Today I took the car for a drive in a light rain, with the wipers and headlights on and made a couple stops in town, started no issues. Drove home about 20 miles and got to my driveway and turned off the car so I could put it in the garage, but left the lights on. Went inside and grabbed a set of keys, came out and the car would not start. I had to jump it..... I did noticed the blinkers were slow when I was coming home,,,,,,, The AGM battery tested fine a few months ago and it's "sits" with a trickle charger on it....... Thinking the Alternator might of went? Battery went bad ( it is 3 years old)? Before I dive into it, I thought I would ask for advice..... It seems odd that the rebuilt alternator from the z store would have gone bad? Before I pull it and have it tested, has anyone had issues with rebuilt alternators?

Any advice is appreciated.......

Everyone on this forum I believe has had issues with rebuilt alternators and starters. Take it to the parts store and have it checked out.
