Technical EPS electric power steering faults

Hi, sorry for late reply. Don't have the graph. Lent it to a friend and "forgot" to give it back. ASAP will upload pic.
But.. there are more news. 2 days after performing the not so successful repair, SWMBO told me EPS worked all day but light was on.
One day later, light was still on and no EPS.
I forgot to tell. The negative earth wire was not good in continuity when tested with multimeter (no beep), and after a lot of sanding the earth strap (which had no corrosion), still showed resistance and no beep.
My earth lead is the "weird" one. I mean, according to EPER the part number has been superceded and now the 51750228 should be used.
But I say "weird" because my earth strap has 2 earth points: one in gearbox and 2nd one in front monocoque leg (ther is no proper "chassis leg", leave that for old land rovers).
The now supplied part only has one earth point. I mean One terminal goes to battery terminal and the other one I think goes to frame, does not look so long so as to reach the gearbox.
What should I do? Fit the new one? But linking battery and body frame or battery and gearbox?. Or should I run another earth lead between gearbox and body?
Best regards

I would run one between battery and gearbox and another between battery and chassis.

Does not need to be a fiat part

From most motor factors just measure what you need

Earth strap eye both ends

One battery to chassis leg
One chassis leg to gearbox

Thank you all. I think I know what I will use... some excellent earth lead from scrpped vehicles my local mechanic has. Used to keep big gauge wire leads for "just in case". Terminal eye hole I think is 10mm because the nut is 13mm. Will crimp and solder the inner cable to terminal and see if that solves problem...
