    Hi All,

    I am having some problems with battery charging on our 03, can anyone help with a copy of a main wiring diagram for an 03 loco.

    Thanks in advance.

    Hi Alan,

    Have you tried the diesel & electric owners group in Facebook?

    They have a ton of useful stuff in there

    I James,

    I've just joined the group and am starting to gather info. As you say a really good group.

    Many Thanks

    Presume it is a 24 volt system with either CAV or Simms dynamo and regulator in which case it will be similar to that as used on 1950/1960s period heavy lorries. You could do worse than call in an automotive electrician.

    Thanks Eightpot, I have found a man who restores old buses, he said he will help. Could still do with a main wiring diagram as much of the wiring is in poor condition and could do with replacement.

    I've got a very basic schematic diagram for an 04 which I don't think will be much different to your 03. If you'd like to p.m. me with your email address I can scan it and mail it to you.
