mcc1979ian Posted June 28, 2016 Share Posted June 28, 2016 Iv just fitted a 300tdi into my 1986 90 but when i bought the vehicle the engine was already removed. Iv found a spare earth attached to the dash with a small ring terminal on the end, question is where would i attach it? Sorry should say in outside of the bulkhead.

vulcan bomber Posted June 28, 2016 Share Posted June 28, 2016 It attaches to a stud on the bulkhead. You can attach an earth to anything made of metal. Make sure it's clean. Quote Link to comment Share on other sites More sharing options...
mcc1979ian Posted June 29, 2016 Author Share Posted June 29, 2016 That unfortunately is the end that's earthed. There is also another earth off the same stud. Quote Link to comment Share on other sites More sharing options...
mcc1979ian Posted June 29, 2016 Author Share Posted June 29, 2016 I mean attached Quote Link to comment Share on other sites More sharing options...
Peaklander Posted June 29, 2016 Share Posted June 29, 2016 Clutching at straws a bit but here is an earth ring terminal behind the clock on my 300TDi if that helps. I can't say where the other end is but you could maybe check if yours reaches that far! Quote Link to comment Share on other sites More sharing options...
GW8IZR Posted June 29, 2016 Share Posted June 29, 2016 Is it a black and black/white wire? trace the wires from the brake master cylinder switch and see if they are related. Quote Link to comment Share on other sites More sharing options...
Peaklander Posted June 29, 2016 Share Posted June 29, 2016 OP says it's in the dash - or that's how I read it! Quote Link to comment Share on other sites More sharing options...

Peaklander Posted June 29, 2016 Share Posted June 29, 2016 It says outside the bulkhead.. yes I see that but I'm confused as it also says Iv found a spare earth attached to the dash I think I'll exit stage left and watch from the wings!

pete3000 Posted June 30, 2016 Share Posted June 30, 2016 had this on mates 90, if it looks too long to go to the stud where you have the other similar ring, it goes backwards along the rail and attaches to the small m8 bolt on the transferbox housing next the the mounting rubber. Trying to find a photo.... Quote Link to comment Share on other sites More sharing options...
mcc1979ian Posted June 30, 2016 Author Share Posted June 30, 2016 Attached it to a small bolt at the side of the block for now Quote Link to comment Share on other sites More sharing options...
