What have I done?

[starmist]

Did the additional starter motor relay yesterday to cure the hot start problems, and since then, the engine is running rough, especially at low revs / part throttle.

What could I have shorted in funbling around doing the mod. I didn't disconnect power and the only thing I unplugged with the connector with the three link wires on it (with the engine running).

I tried disconnecting the ECU today, with no effect.

All the symptoms are the same as I have when my rotro arm as on the way out, but I only cahnges that a couple of thousand miles ago, and I can't have buggered that fiddling with the wiring, can I?

Is the alternator still working ok?

ECU hasnt gone into limp home mode has it?? have you tried resetting it.
Must say I wouldnt have cut into them wires with engine running Mod-wise instructions say to stop engine before cutting wires.
Dont know what else to say but hope you get it sorted.

Alternator appears to be okay - certainly no lights. Possibly cocked up when cutting wire with engine running, but since this only feeds the startr motor (and I got the right wire first time) I can't see what difference it could make.

Perhaps someone can tell me?

Have you tried mailing David(nod-wise), hes the guru with Griffith electrics, hopefully he might be able to help.
looked on a couple of other sites from the other thread that hadve doen these mods on other v8,s taht have suffered the same sticking/to small a current and cant see what you may have harmed.
It seems a pretty easy mod to do, but something has been upset, only wish I could help and new what.
Does the starter feed go to anything else?? Alternator(as said before)/ignition coil??

would thought it more likely you've disturbed something else.

check wiring/air leaks in induction in the areas you were working in.

All my work was done in the passenger footwell.

What's this limp-you-home mode? I like this idea? what does it do, what could have caused it, and more importantly, how do I get rid of it?

I'll mail David Beer offline.

BB, could you tell me how to reset the limp home mode, please?
