Thermostat.

Negative Temperature Coefficient Thermistor Test.

Tested the resistance by measuring the resistance between terminals of the thermistor by heating water up at different temperatures ranging from 15-80 Degrees Celsius using a thermometer to determine the heat. Then testing the thermistor's resistance with a multimeter at each point going up in temperature 15,20,30,40,50degrees...etc

Manufactures specs: Cold= 2000-3000ohms. Hot= 200-400ohms

My results were well in specifications as when the water was only 15deg. the thermistor showed high resistance (2.95k ohm's) and when the water was 80deg. I got a reading of only (.360k ohm's) this shows the thermistor was working upto scratch and would operate with no problems.

Testing Ignition coils

Obtained two different coils.

Coil 1 Specifications:

Model: Ic-13

Voltage: 12v

Primary: 1.5-1.6 ohm's

Secondary: 6-7k ohm's

Test results:

Primary: 2.1 ohm's

Secondary: 6.7k ohm's

Earth leakage test: Infinity

Coil 2 Specifications:

Model: Ciz-500

Voltage: 12v

Primary: 3-5 ohm's

Secondary: 7-9k ohm's

Test results:

Primary: 3.7 ohm's

Secondary: 6.9k ohm's

Earth leakage test: Infinity

Before you pursue tests always test the meter error in the multimeter you are using first, as there can be resistance in the wires or in the system of the multimeter, My multimeter had 0.1 ohm's of resistance which you deduct off your test results recorded..Both coils were out of specifications and are unserviceable.

Injector Patterns,Delivery volume & leakage.

Injector spray pattern: Pattern should be an even cone shape without any distortion or hard lines of fuel running through it.

Offset spray pattern: dirt or build-up on the nozzle seat can cause the spray pattern to be offset to one side and give poor atomisation.

Delivery volume: Fuel flow should match the manufactures specifications and there should be no variation across the injectors, also the ecu opens the injectors for the correct length of time but any dissruption to the fuel flow can cause the related cylinder to run lean.

Injector leakage or dribble: When the injector shuts off there can be drips of fuel, due to fuel passing the seat and dripping into cylinder.this can cause hard starting and high fuel consumption.

Injector spray patterns

Had to test and check four injector's for there: Condition, Spray pattern, Flow rate & Leakage(dribble).

I had use of a fuel injector tester, where you can set up four injector's and squirt fuel through them hanging in a glass tube so you can visually test the injector's spray pattern,flow rate and dribble.

I found that the spray pattern on three of my injectors was fairly even with no offset spray so these injectors would operate fine, yet one had major offset and would operate poorly due to there being poor atomisation in the cylinder.

The flow rate of all four injectors was (60ml-20sec) 180cc. of fuel per minute. which met the manufactures spec's.

There was no dribble or leakage in all four injectors I tested this by spraying fuel out of the injector's and then shutting it off, Then looked for any excess fuel to dribble out but none was recorded.
