Another disturbing noise from Ruby

[Denis Sweeney]

John, as I noted in an earlier post, I had the battery checked by the supplier and he had advised it was all ok.
So have just checked again making sure the meter probes were made directly to the battery posts and there is virtually no die off at all, reading 6 volts when trying to turn the motor.
However anywhere downstream of the terminals and this falls to 2 volts when the starter switch is engaged.
