carlosbeldia Posted April 20, 2010 Share Posted April 20, 2010 Today I was cruising with my 110 when suddenly all instruments in dash went off..... right now I don't have fuel gauge, temp gaugem speedo, odo, nor turn lights. Also, car started to jittering when accelerate, as if wastegate arm was stucked, but check and everything is OK. I Checked all fuses and relays, all is OK. Any idea? Nanocom instruments mode shows all values with no problem, so I suppose it's a ground conection, but don't know which one. I have just checked 2 chassis one and 2 passenger base one, everything loos just fine,..-..... Quote Link to comment Share on other sites More sharing options...
tommac Posted April 20, 2010 Share Posted April 20, 2010 certainly sounds like a ground issue- not much help, sorry- have you checked the ground terminal by the ecu? Quote Link to comment Share on other sites More sharing options...

carlosbeldia Posted April 20, 2010 Author Share Posted April 20, 2010 Somebody told me about a ground connection in a white box in engine bay, can anybody be more specific with photos or instructions please? Quote Link to comment Share on other sites More sharing options...
SiWhite Posted April 20, 2010 Share Posted April 20, 2010 On a Right Hand drive vehicle, the earth point you are looking for is just by the clutch master cylinder, held to the bulkhead by a stud and nut. Follow the loom as it leaves the bulkhead going towards the front of the vehicle - one set of wires will be a group of black earth wires which will run to the white box.

SiWhite Posted April 20, 2010 Share Posted April 20, 2010 Stupidly small pic from the workshop manual.... C0550 is the one you are after - might be different if yours if a left hand drive.... Quote Link to comment Share on other sites More sharing options...
carlosbeldia Posted April 20, 2010 Author Share Posted April 20, 2010 Thanks a lot Simon. I have checked and don't have this little box near the inertial or the water deposit. I found these bolt (I think it comes from the fuse box held, one of the two bolts that fixed it to the bulkhead) and the space near it seems to held something that isn't there: I see this free fixed poins here, do you think the white ground is the thing that is not here: Quote Link to comment Share on other sites More sharing options...
carlosbeldia Posted April 20, 2010 Author Share Posted April 20, 2010 Simon, can you please let me know in what section of the workshop did you find this photo? my manual doesn't have photos, only diagrams. Quote Link to comment Share on other sites More sharing options...
SiWhite Posted April 20, 2010 Share Posted April 20, 2010 Carlos - send me your email address by PM and I will forward it on. Check the other side of the bulkhead for the white box - yours is left hand drive? It is in front of the driver, in the engine bay. Quote Link to comment Share on other sites More sharing options...
carlosbeldia Posted April 20, 2010 Author Share Posted April 20, 2010 PM sent. I'll check the other side and let you know. Quote Link to comment Share on other sites More sharing options...
carlosbeldia Posted April 24, 2010 Author Share Posted April 24, 2010 Thanks to everyone for all the help. It seems that my car doesn't have the white box or the additional ground in the engine bay. Problem was solved last night,..... it only was to clean up the start engine terminal and everything seems really ok right now.... let you know if anything change.-...
