.Connect the negative (-) lead to the negative (-) battery terminal.
.Set the MinIMax feature on the meter.
.Start the engine and hold a 1500 RPM.
A reading of 13.1-15.5 volts is an acceptable charging rate.
Ignition System Tests
[1] Ignition Coil, Primary Resistance Test (Ω)
This test checks primary winding resistance.
IMPORTANT: Test the ignition coil cold and hot.
.Set the rotary switch to the Resistance (Ω) setting.
INSERT:
.Black lead in COM terminal.
.Red lead in V/Ω/RPM terminal.
.Disconnect the coil from the vehicle wiring harness.
.NOTE: The resistance in the meter leads must be subtracted to get an
accurate measurement at the 0.50-2.0 range. Short the leads together
and press the ZERO ∆ Button. The meter will automatically subtract the
resistance in the leads.
.Connect the negative (-) lead to the negative (-) terminal on the coil.
.Connect the positive (+) lead to the positive (B+) terminal on the coil.
Typical measurements are between 0.50-2.0 Ω's consult the manufacturer's
specifications for required resistance measurements.
[2] Ignition Coil, Secondary Resistance Test (Ω
ΩΩ
Ω)
This test checks secondary winding resistance.
IMPORTANT: Test the ignition coil cold And hot.
.Set the rotary switch to the Resistance (Ω) setting.
INSERT:
.Black lead in COM terminal.
.Red lead in V/Ω/RPM terminal.
