WS1 Petrol Fuel Injector Testing

This part i was testing the injectors but one bit i couldnt do casue i cant hear the sharp tap. so a friend came and did it for me and all the 4 injector was working fine and good conditions

I was testing the voltages by using the voltmeter and pins i put the pin on the injection on the wires of postive so it a red wire and tested and the result for CYL1 is 13v CYL2 12v CYL3 13v CLY4 12V
So all the injector are working well.

The next bit i used the LED Tester it like the probe has 2 light leds
 all of the 4 injectors were okay and they green light flashing so it a good conditions

Iding the injector using the multimeter and i set to % duty cyle n record the readings while the eingine is on
CYL1 9.86% CYL2 98.9% CYL3 9.86% CYL4 9.86 i think all of them are the same

this stil the same as the top one but this i use the throttle and rev it up and these the reading i found

CYL1 6.19%  CYL2 6.41%  CYL3 6.19%  CYL4 6.14%

i dont know why all of them not the same because i rev up random times didnt follow to like 2000rpm

Setin up the muitimeter to Hz and engine on to idling. the reading came up

CYL1 0.09hz  CYL2 0.10hz  CYL3 0.09hz  CYL4 0.10hz.

same as the above but this time i increased the engine RPM to 1500 and i got the reading

CYL1 0.25hz  CYL2 0.29hz  CYL3 0.25hz CYL4 0.29hz

this the reading numbers that i tested using the throttle n revin it up and i see the numbers the more rev i do the numbers go higher.

showing the calucations if u cant see it very well click on the pic and u will see in larger


Atfer calcatution all the readings it showing below this picture


those reading and  calacation they are working and accpetbale to injected. And i have learn how to test the voltages for the injections and how to back probe and using the muiltmeter.
