TM 9-2350-261-20-1 STE/ICE-R BATTERY TROUBLESHOOTING — Continued 0103 00 2Y 1. Check to see if batteries’ resistance changes less than 50 milliohms/seconds. 2. Does batteries’ resistance change less than 50 milliohms/seconds? 2YN NOTE If batteries fail in freezing weather, crank engine for five seconds and retest. This will warm the batteries slightly. 1. Check batteries’ electrolyte level. 2. Clean battery terminals. 3. Check batteries’ specific gravity. 4. Charge batteries, if necessary. 5. Repeat test on this battery. 6. If batteries have been charged and batteries’ resistance change still exceeds limits, replace battery. 7. Verify no faults found. 3Y 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? 3YN NOTE If batteries fail in freezing weather, crank engine for five seconds and retest. This will warm the batteries slightly. 1. Check batteries’ electrolyte level. 2. Clean battery terminals. 3. Check batteries’ specific gravity. 4. Charge batteries, if necessary. 5. Repeat test on this battery. 6.
