[4] Battery Test (Load)
This tests the battery
’s capacity to
deliver sufficient cranking voltage.
·
Set the rotary switch to
Voltage.
·
Connect the positive (+) lead to
positive (+) battery terminal.
·
Connect the negative (-) lead to
negative (-) battery terminal.
·
Disable the ignition; crank the
engine for 15 seconds.
Check the Min. display. A reading of less than 9.60V@7
0℉
indicates a weak
battery. Recharge/replace before testing.

Rresistance, What is it ?
Resistance is an opposing force, created by a circuit or component, to the flow
of electrical current.
There is a small amount of natural resistance when voltage flows though wires,
switches, grounds or connections. The resistance increases beyond acceptable
limits if corrosion develops, fittings become loose or wire fray. Resistance
Increases each time something, such as wire, a switch, connections, or the
ground are added in the circuit.
Voltage Drop, What is it?
Voltage drop is the difference in voltage potential when measured across a
