Hi Jeremy
I am Ok with the use of a multi meter, My problem is to try to get access to a electrical drawing to see what is missing. As there is a 18v reading on the battery when running the engine I am assuming that the regulator is not latching one of the relays to reduce the output.

Fitted the new regulator still the same problem 18volts on the battery when running.
Has anyone got a electrical drawing for the regulator and alternator? Or can you advise on how to locate the fault any help will be appreciated.
