Question about Ford Ranger
After replacing the alternator,my gage still is reading a low amp
One way to be sure the gauge is right is to put a voltmeter on the battery with engine running. If the voltmeter reads under 13 volts, alternator is not working. Voltmeter should read 13.5 volts up to about 14.5, in that range. If the alternator is not working, check for a blown alternator fuse in the power distribution box, and recheck alt. and batt. connections. A loose connection anywhere there will prevent alternator from working.

I had this car about 10 years ago. Loved it!
You must either clean or replace the battery cable. The corrosion is not allowing the charge to get to the battery.
Many parts houses carry a battery post/terminal cleaner that will aid in getting all of the crud away from the terminal.
You should be sure to remove all of the corrosion!

find out if the voltage regulator is built in the alternator,
if not find it and test it.
If it is, it could be bad plugs for the alternator or bad wiring in the charging circut

Check the voltage regulator and check for any loose grounds or connections.
