Hey Guys,
I have a 96 K1500 Z71 with the 5.7L Vortec that's all stock. A couple months ago I noticed that my voltmeter would dance drop to 11-12v when I put on the blinker. Lately it's gotten worse to where I can visually see a voltage drop in the interior lights when I press and hold one of the windows switches for example even after it's up all the way to create increased load. If I put too many accessories on the truck appears to have a minor idle stumble.
The battery is a one year old Optima Red Top, the alternator is a brand new AC Delco unit. I just put it on yesterday hoping that would fix things. While the needle swing is less, it's still there and I can see the interior lights dim when I create load on the system. It didn't do this before. All other gauges work perfectly.
Any ideas? Is this a bad battery causing the alternator to work harder to recharge it when it's running there by causing the more than normal volt drop when I create a small amount of load on the system? What else should I check. BTW, I don't have a hand held voltmeter .
