Cheers TerminatorX5, thanks heaps for the prompt replies.
I wasn't aware of the "Cluster" tests... i will do a search now.

At this point i measured with my multimeter at the battery terminals;
12.25 Volts Floating Voltage (Vehicle not started key removed from ignition)
14.14 Volts Charging Voltage (Vehicle running at idle)
I will check and concur with "Cluster" test soon
