This is an LH2.4 swapped 740, using a 940 loom so I may have done something wrong, or just badly...
There seems to be an intermittent signal from the EZK to the ignition amp/power stage. So far I've only seen a single spark after several attempts cranking the engine. I've checked the signal going to the ignition amp, most of the time it doesn't vary, staying at about 180mV which I believe is in the right region for having the ignition on, but it should pulse with a slightly higher voltage when cranking.
I know what the inputs into the EZK are, but I don't know which ones are strictly required for it to send the ignition signal? I checked out the crank sensor, resistance seems ok. I read it's supposed to produce about 0.3V when cranking. I can't measure any voltage, however I must be doing something wrong because I also can't measure any voltage on my running 940.
I'm sure the crank sensor is fine but I guess I should confirm this first, so what's the best method (in detail) of measuring the crank sensor voltage when cranking? Failing that, I can just swap the sensors between my two cars. And what inputs does the EZK strictly need to send the ignition signal? Any other advice appreciated.
