I went to autozone today for get motor oil, and asked them to do their free load/battery test.
The guy first does the batt test.... we wait for 25 seconds or so.. then display says
"Charge & Retest"
Then he connects I guess something to one of the batt cables & asks me to start & hold at 2 K rpm for a few secs.
Then, presses some keys, and says that my alternator is weak. Display shows...
- output is only 4.9 amps... He says its should be 60% of the alternator rating???
- the other message says "diode pattern good"
any inferences... I dont have any problems starting... but I feel the esp the head & even tail lights are all weak/dim.....
