Battery Ground Check.
A check of the battery ground connection can be made to assure the negative battery cable has a "solid" ground
connection to the unit frame. Perform the check as follows:
1. Check that the negative battery cable is securely attached to the negative (-) battery terminal and the unit frame.
2. Connect the positive lead of a dc voltmeter to the unit frame close to the negative battery cable attach point.
NOTE
A DC VOLTMETER WITH A 15-VOLT SCALE (MINIMUM) SHOULD BE USED FOR THIS CHECK.
3.
Connect the negative lead of the voltmeter to i.e. negative (-) terminal on the battery.
4.
Motor the engine with the starter. The voltmeter should indicate "zero".
5.
If a voltage reading is indicated on the voltmeter, clean and tighten the unit ground connection.
6.
Disconnect voltmeter leads from battery and unit frame.
