'93 GL 3.0 This began about 6 mths ago. Occasionally and seemingly randomly, my battery light blinks on. Not under the same conditions and never stays on, just briefly blinks and goes out. I checked all the connections to the altenator and battery. Everything was clean and tight. The alt was making lots of noise which I assumed was the bearing going bad (170,000+ miles) so I replaced it. Nice and quiet now but the light still blinks. I just replaced the 10 yr old battery because I didn't think it had another winter left in it and this also made no difference. The belt is recent and the tensioner seems strong. What should I look at next?? thanks.
