2002, Ford Ranger, 3L Engine
With a Voltage Meter Gauge plugged into Cigarette Lighter,
I am noticing an Alternator output fluctuating between 12.2V and 14.4V while driving.
The Battery Light on dashboard came on and Dash Gauge showed near the 'L'
Battery: Replaced 3-1-19 / Walmart EverStart 590 CCA
Alternator: Original
Because the Voltage is fluctuating every 30 seconds, my testing options are limited.
I have inspected:
1) Drive Belt
2) Tensioner Pulley
3) Alternator Wiring
4) Battery Connections
5) Use my Computerized Battery Tester and it shows ALL Good
I'm guessing it's the Alternator, but wanted to get some other opinions.
Any help will be appreciated.
