1996 Cherokee Battery Gauge drops using defrost
Hello, first let me thank you for a place to ask a question. I have a 1996 Jeep Cherokee Country. I need some good advice because money is an issue, after just replacing a heater core and battery.
It has been sluggish to turn over, I thought perhaps because it was cold out.
I had my battery and alternator checked today. The Alternator was charging, but I had to replace the battery. It was old, so I thought nothing of it.
I started it tonight, and turned on the heat. When I am parked using heat it made the battery gauge drop a bit, while still parked I turned on defrost and it really dropped down to a little above 9. So I shut off the defrost, and drove- while driving I tried it again. It drops slightly below 14. Sometimes when i turn on defrost belt seems to squeak- if this matters. What is causing this? Is it safe? Any ideas?

Check the belt tension, in defrost mode the A/C clutch is energized and will draw some current.

Think its just a belt doing it?
Voltage drop happens with A/c. heat, vent and defrost- squeak only on defrost startup. Squeak stops after a while....So it may just be a belt?

The heater fan is going to draw some current too. The noise is most likely the belt squealing, the A/C clutch puts an extra load on the belt.
