All it takes is a single (missed) strand of the shield (connected to the
core) to create a short.
remove the connector(s) from the EC2
and check with an ohm meter between each pin on the connector and to ground (for
pins that don't go to ground) for shorts (0 ohms). Thanks Finn. I
checked that as I went, and again (twice) after everything was buttoned
up.
realized that you used shield wires, did you shield all
wires? Don't know what type of wire you used, maybe you mentioned it
somewhere. Shielded wire can have a lot of capacitance
I used shielded 22g
aircraft wire for all EC2 inputs to the PCM (program control module) and
EM2. The shield for each is grounded at the EC2 end only. Resistance
measures around 0.3 ohms on each wire. The EC2 manual calls for shielding on injector and CAS wires only.
Tracy suggested I shield all wires to eliminate noise. I could try disconnecting
the shields if you think it might help - but doesn't that put me back in the
"noise" regime? Might be a good idea. Right now a little "noise" would be kinda
refreshing. :(
