OK electrical guru's what the heck should I do now? (CIS air idle control valve meas)
G'day Folks,
I'm still struggling with electrickery. I want to test my air idle control valve on my M102. Book says the current should be 580 mA +/- 50 mA after a 28 second period due to heater on air intake and at an idle of 700 to 800 rpm So I got me the expensive cable ![]() M102 / M103 CIS test cables Plugged it into the parts I'm meant to => ![]() ![]() ![]() Connected the end to the multimeter ![]() And the bloody engine stalls! It seems like the impedance of this auto-ranging multimeter is too high (or summit like that) and that causes the engine to stop. I've tried to make the measurement with "less good" multimeters I have with a switch-able range such as the one in this picture => ![]() And the bloody engine still stalls when I switch to the appropriate 0 - 1 amp (was it?) range... ....hmpf - not impressed. Any suggestions? One of those gucci clamp round a wire current meters?
