The test light will not help you-it doesn't give you the amount of electrical pressure being produce-

Get a voltmeter and measure the battery open voltage-should read 12.4volts or better-then start the vehicle up and read it again with the heater and headlight at high it should be in the range of 14.5 or better-if so the charging system is okay-
