I have a Ford 4000, mid 1970's. I have fitted a new dynamo but find that the light on the dash remains on, as it did with the old dynamo. I've checked what I can on the wiring loom for any loose connections and find none. The battery doesn't appear to charge well, if at all. Any suggestions to sort this are welcome.
Many thanks
