Testing igniton ciol

Testing igniton coil.
Method
1 two diffrent ignition coils configrations.
2 List all coil part number , voltage , internal resistance specations .

Coil Specificatios

Coil # 1 NO ...CIC31                       Coil #2 NO...CIC32R

Coil# 1 voltage..12V                        Coil #2 Voltage..12V

Coil # 1 primary ..3 - 4 ohms           Coil #2 primary..3 - 4 ohms

Coil # 1 Secondary.. 7 - 8 K ohms       Coil #2 secondary..7 - 8 K ohms

Coil test results

Coil # 1 primary ..3.5 ohms

Coil # 1 secondrar  9.4 ohms

Coil #1 Earth leakage OL

Coil # 2 primary  1.9 ohms

Coil # 2 Secondarary 9. 4 ohms

Coil # 2 Earth leakage test OL

Both coil get specificaton not serviceble (OK)

Extra explaination about coil:
Secondary winding which is 100 times over the primeray winding, inside primery and secondary windings iron soft cone.

when the ignition coil is connected to the battery the inductor is get charged it is take afew mille second for the current to bueild up the energetec field this on accut of revers voltage caused by increase field .

During this short charging peried a thusand volts are produce at the high voltage terminal not enugh to actulay cause a sprk . The actual spark is generated with the braker contact open.

Wasted Spark coil pack test.

Coil # 1 Secondary  9. 48 K ohms

Coil # 2 Secondary  7.33 K ohms

Coil # 3 Secondary  7.34 K ohms

Coil #1 Primary      0.1 ohms

Coil # 2 Primary     0.6 ohms

Coil # 3 Primary     1.1 ohms

Testing Ballast resistors

I have two diffrent type of blast resistors , i meassured the resitance and specification.

Specifications

Ballast resistor 1 NO BR1                     Ballast resistor 2 NO BR2

Ballast resistor No 1 ohms spec 0.9 - 1.1 ohms      Ballast resistor No2 ohms spec 0.5 - 0.7 ohms

Meassured Resistance Values

Ballast resistor NO1 measured ohms 4.2 ohms        serviceble? NO

Ballast resistor NO2 meassured ohms 2.5 ohms       serviceble? NO

                                        meassure of Ballast resistor NO1

                                           Meassure of Ballast resistor NO2

Meassuring Current Draw and voltage Drop

Stander Signal tower coil

I have wired up the coil primaty winding with  ballast resistor folow that drawing diagram.

In this picture i had connect an ammeter in series measuring current draw 3.414 Amps

Coil calculate Voltage Drop  4.7 Volts

Coil meassured Voltage Drop  3.93 Volts

Ballast resistor calculated voltage drop 5.96 volts

Ballast resistor measured voltage drop 6.27 volts

Did your calculated values equal your measured results explain why or why not?
Voltage drop are equal as the ohms law say
Calculated value:
Ballast resistance . . . . . 1.9 ohms
Coil resistance      . . . . . 1.3 ohms
Coil volatge drop  . . . . . 4.14 A * 1.3 ohms = 5.4 volts
Ballast resistor voltage drop 3.14 A * 1.9 ohms = 5.98 volts
