"•Harbor Freight sells an inexpensive 500 amp adjustable load test machine. I love it as doing a load test alongside a hydrometer inspection and equalization is a great dose of truth serum." I bought one of the load testers and I really do not understand the test or the results when used on a pair of 6 volts? Could one of you knowledgable people explain it to me? Thanks Alvin
HF 500 amp tester manual (in case you don't have one).
You need to know the amp hour rating of one of the two identical 6V batteries. Connect the battery clamps from the tester to your batteries. Turn the "Load" knob on the tester until the left side analog meter reaches the amp hour rating. Wait 10-15 seconds and read the indicated scale on the right analog meter of the tester. It should point to the Green ranges if your batteries are good and charged.
