91 D21 - Battery Light Half Illuminated

[superhpman]

Hi,

I have recently noticed when I crank my truck, my battery light will illuminate about 1/2. My dashboard lights, headlights, and heater will also illuminate about 1/2, until I drive around the parking lot about twice. Then everything will restore to full.

The battery is 3 months old.
Just had a new starter put in.
Alternator looks to be new as well.

I have had the above checked at Advance Auto, the above checks out on their tester.

I was wondering if anyone might have some advice about this issue?

looks like it was the alternator

Yea, if not the altenator itself, probally the regulator on the altenator. The altenator itself can work, but if the regulator is bad, it can put out too much voltage or not enough. Had same problem years ago.

aye, I had a power steering hose explode on my truck a while back. when we took it off, it was caked in fluid. thinking that was the culprit
