IMPORTANT: Verify that both batteries are in good condition.
1. Disable the fuel system by removing the fuel solenoid fuse.
2. Calculate the current draw. Select the 200 A or 2000 A scale on the current clamp.
3. Zero the current clamp. Clamp the J 39200 to the negative battery cable.
4. Crank the engine. Observe the meter readings. The reading should be 330 - 360 amps. If the amperage is over 360 amps, an internal starter failure
may be the cause. If the amperage is under 330 amps, a battery cable or connection may be the cause.
