MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
7. SOLENOlD OPERATES, STARTER OPERATES, BUT ENGINE CRANKS SLOWLY
NOTE
If STE/ICE is available, perform NG80 - Starter Circuit Tests
Test 1. Check batteries for overheating. Crank engine for 15 seconds. Check batteries for
overheating by feeling battery terminal connections. If battery terminal is hot, a loose or
corroded connection is indicated.
a. Clean corroded connection to bright metal.
b. Tighten all loose connections at batteries, ground, and starter.
Test 2. Perform a specific gravity test (TM 9-6140-200-14). Batteries must be 1.225 or greater,
temperature corrected, and each cell in a battery must test within 25 points of the others.
a. Charge all batteries not meeting requirements, and check specific gravity again
(TM 9-6140-200-14).
b. If 25-point variation still exists, replace battery(ies) (para. 3-125).
Test 3. Test starter voltage.
Step 1. Set multimeter to 50-volt range.
Step 2. Connect multimeter positive lead to positive terminal stud of starter and negative lead
to terminal stud on end plate of starter.
Step 3. Crank engine and observe voltage reading on multimeter. Voltage reading should exceed
22 volts.
If voltage reading is low, clean and tighten connections.
