Running on 4 cylinders, Emerald ECU

Always a good recomendation. When you here it on a place like this.

Receivedan email from Emerald, stating that the driver had possibly been overloaded.
He suggested I check the resistance of the injectors, should be between 10 and 16 ohms, easy enough.

But then suggests "Also check that there is not a +12v short to the injector signal wire, i.e. between +12v and ECU pin 1."

Can someone explain in electrical numpty terms? Thanks

He means get a meter and check continuity between +12v supply and pin 1 on the ecu.U know when u set the meter so it beeps/buzzes when u touch leads together. Put one lead on the +12v supply and other lead on pin 1 of ecu. If it beeps u have a short, well according to what u say. If it doesn't and gives u a infinite reading u are ok

[bubba_1986]

to check the resistance of the injectors set your meter to ohms and within the 0-100 range, or lowest u can. Use both leads either way on terminals of injector and take the reading off of the screen and compare

Hope this helps

Thanks Bubba, makes sense now.
Tested injectors all read 14.5 Ohms.
Will check for a short later. Had a word with the electrician, he says a short would be obvious, melted solder or burnt wiring.

Dave walker at emerald is a top man, always willing to help and a clever bloke, got a few mates who have had work done there, and can't praise them enough!

Tested wiring as Bubba suggested, no faults, so refitted ECU.
Running on 5 now, sounds much crisper and livelier.
Thanks guys for the help and advice.
