Whoa...I probably wouldn't pass the ASE test again...

THAT is a good link. I did OK, missed a couple on that one, more on the other pages:
Try these too:

Question #26 appears to be incorrect. It sez:
An AC Delco battery with a built in hydrometer is being checked. Technician A says that a DARK GREEN eye indicates the battery is sufficiently charged for further testing. Technician B says that a CLEAR hydrometer eye means the battery must be replaced.
And the correct answer is supposed to be "B". "Correct. A clear or light yellow hydrometer eye indicates the battery is low on electrolyte and should be replaced."
However, that indictor is NOT a hydrometer, it is an electrolyte level indicator. Therefore, the answer "B" is incorrect. Indeed, the earlier Question #17 correctly defines what a hydrometer is:
"Correct, a hydrometer is used to measure the specific gravity of the electrolyte."
Anybody here old enough to remember rechargeable batteries for radios that had three different density balls floating in the electrolyte? (You could judge the state of charge by noting which balls were floating.)

3 of the answers are wrong for the second test:
On the other hand I missed 6 on the first test:
Voltage only Truly reflects "charge" if you are using a capacitive (no load) voltmeter.
It's not how low it dips, it's the recovery point that determines if a recharge is in order. The dip depends on internal resistance and the external load, if any!
What's a passing grade? I didn't get below 80% on any of the tests, and I sure don't know much about cars. Is that why so many ASE certified mechanics are bad?
