1. Do batteries resistance change less than 50
milliohms/seconds?
1. Set test select switches to 73.
2. Press and release test button.
3. After GO appears, engage starter until OFF appears.
4. Is battery internal resistance less than 25 milliohms?
1. Batteries are OK.
2. If display shows GO, there is a bad connection in the
starter circuit. Check cables and connections to starter
andrepeat test.
3. If GO is still displayed, then you may have a very poor
battery in the series pair being tested. Test each bat-
tery individually.
4. If display shows .9.9.9.9., there maybe a bad connec-
tion on the battery being tested. Clean and tighten the
connections on the batteries and repeat test.
5. If display shows E013 or .9.9.9.9., the batteries being
tested maybe in a discharged state. Checkbatteries
electrolyte level; charge batteries and repeat test.
6. If display shows E013 three consecutive times, or
- - - -, or .9.9.9.9. after batteries have been charged,
replace battery.
7. Verify no faults found.
