JCB starter wiring

Would anyone have a wiring diagram for a 3CX Project 7

Igot a new starter motor to fit but didn’t remove the old one myself so not sure what goes where

cheers

IIRC my '87 black cab had its own earth -- guessing the blacks attached to the ring in your pic ... goes on that big body pole and won't function without it ... rest're all to the live supply pole to the solenoid, plus the energiser spade to the solenoid terminal ... Solenoid may also have an independent earth to isolate it when in gear ??

At a glance, there looks to be a large cable missing, where are the cables going to? The bunch of red cables on the left in the photo look like your live feeds to your ignition switch/ fuse box, the smaller ones would be starter solenoid.

This is the diagram you need (from above).
Battery Positive to H
Battery Negative to B (poor choice of lettering)
Start switch to C

All the extras also go to H as this will feed the fuse box etc.
