Testing ignition coils- off car




Results: COIL 1 primary windings- 2.8ohms
secondary windings- 9.35kohms
earth leakage- ol
COIL 2 primary- 1.2ohms
secondary- 8.77kohms
earth leakage- ol

note see picture to see how you place your multimeter.

Measuring current draw and Voltage drop:

Current draw- 3.60amps
Measured coil Voltage drop- 3.84volts
Measured ballast resistor voltage drop- 6.12volts

Calculated values: v/r = amps 12/ (2.8+ 1.4)= 3.75amps #2- 12/ (1.2+1.5)= 4.4amps

The first calculated result was good but the second calculated was not so good. Maybe the coil was too good with continuity giving low resistance
