Discovery 200tdi starter motor wiring

D1200 · May 31, 2021

Hi all, ive reshelled my 200 5dr into a 300tdi 3dr shell and just coming to plug the last of the wires in and the labels are now unreadable so was wondering if anyone can help.
Ive got a large (4/5mm) brown cable with a ring fitting, a small (1/1.5mm) black cable with ring fitting and a 2mm ish red and white female spade fitting.

From what i can remember the brown goes to the postive on starter solenoid and to alternator? And red and white is exciter wire for starter? Does this sound right? But i have no idea where the small black ring goes? Any help would be much appreciated
Sorry for poor pictures.

Thats brilliant, thankyou very much kind sir il get everything else plugged in and im sure the little black one will show its true place

I'll have a dig around to see if I can find a similar wire / terminal, theres various wiring differences on D1's as I've found out, possibly year-to-year but maybe spec. related?

my pair have verry different looms....

The black wire doesnt really look like it was originally there, maybe it had been added as a live feed or an earth for something else.
Either way I'm going outside this afternoon so can pop my bonnet and take a look too (RRC with D1 200tdi)

I didnt think it would be related to starter it just hangs around that area. Once thats wired in ive just got to change the ignition barrel to a 300tdi as im using the steering collum from one

stupid question but.....

where does thet black wire go?

Possibly maybe could be a feed for a fusible link?
Iirc early 200tdi had fusible links buitl into the wiring loom, possibly drivers side inner wing area?

Mines from a late 200tdi that i had for a couple years. But to be honest i dont remember removing it from anything a few months ago. Il leave it out and see what else doesnt work

Afternoon peoples..
Ive been to play with the disco today and still cant get the starter to turn. Ive wired it all up now (correctly i hope) and all that happens is starter relay clicks when key is turned. Ive had issues before and have had to bridge the started to get it to turn but i tried that today and i got a very weak spart and no attempt to turn it over. Am i missing something? Theres no 'left over' wires dangling about and cant see any earths that ive missed. Got 2 wires on one pole (red, brown) and exciter wire to spade terminal and earth strap from chassis to bottom bolt on starter. Any help would be most appreciated. (Exciter wire not attatched in pic)

Yep your battery is flat or starter is fubar, or dead spot on commentator,,
If you bridge across the two nut terminals with heavy gauge wire the starter should spin if there is enough voltage,
It won’t turn the engine over because the solinoid hasn’t engaged the bendix,
The clicking you hear is the solinoid working,

Don't hold the wire in your fingers though, could get scarring hot

My money would be on the starter itself then, i didnt have any decent gauge wire to hand so used a 19mm spanner and it just gave a very very weak spark and nothing from solenoid. Ill pull it tomoro and try take it apart and see whats what.

So.. ive just bench tested the starter (bosch and only 4 years old) and its absolutely fine so im going to pick a good battery up tomoro and then re test on the truck
