The "All Spark has lost it's spark"! LOL
I have 3 jeeps down all at once now (must a planetary alignment thing), may be riding a bike next,
I need some quick, correct answers, feedback on my new thread so I can narrow this down to the CPS, or Ignition module-Coil, ICM tonight if possible.
I have no spark from the coil, nada, nothing.
I have forgotten a few key details on how to test the feed to the ICM to see if I have a signal to the ICM (and thus the ICM would be bad), and I am trying to recall if the CPS can be tested live while the wires are ("previously cut and soldered by a prior owner" :tears: in a tight space , no room left in the wires) still connected in the harness.....
My 89 Renix has the CPS wires soldered ( no QC) to the harness wires.:banghead:
Has any one ever tested the CPS while connected. I have an analog volt - ohm meter, so I can test unpowered ohms, or ac/dc signals with needle style meter (not digital) but what number do I want to see with it if the CPS is connected to the harness for Ohms??? What is the running CPS voltage peak minimum needed for live cranking test, and was that for an isolated CPS, or one still connected to the ECU - harness tests? I knew all this shit once, just been too long.
I want to look at my options as the two wires are short, no real room to cut and splice extra wire, the way the prior fools did the solder mod.
Also isn't there an ignition wire module input wire I can test, while cranking to see if the CPS signal got to the ECU, and the ECU signal is getting to the ignition module? What is the signal voltage to the ignition module? Is it the yellow wire I would test while cranking? Is it a DC pulse signal that registers as AC? I know the CPS signal wills show up IIRC on AC or DC low volts, 0-1 volt IIRC?
I guess I may need to unsolder the old connections for the CPS to get an ohm test on the CPS.
Thanks!!!!
