Starter motor wiring

[ballbagbagins]

Hi, I've replaced a starter motor in my lupo and I need some help with reconnecting the wires to it please.

The engine and engine loom are from a 1.8t and I didn't take a picture of the starter I removed so I'm assuming the two cables I'm looking at should be connected back to the starter.

I think one cable is power and the other is earth. One thing I did so was to connect both cables to the threaded terminal, all that did was melt the cable I think is the earth.

I'll try and post a pic bow.

Starters earth through the body so there is no separate earth, typically they are wired either inline between alternator and battery positive or have a separate cable to the battery positive

Looking at the stud on the starter bolt the earth may attach there which may have led to your confusion and melty happenings

The earth attaches to the stud connecting the starter to the gearbox?

Yea, on the end of the bolt with the 13mm nut on it, the 13mm nut retains the earth strap.

Thanks very much for both of your help. I just need to buy a new earth strap.

Thanks again.

As a boost pipe popped off whilst on the m6 today, I got a hard shoulder visit from the AA. The lovely AA man donated me a spare earth strap as well as refitting my boost pipe.
