NOTE:- . It is important that terminal 60 ( sender common ) is soundly connected
to an earth point on the ENGINE BLOCK, not within the control panel and must be a
sound electrical connection to the sender bodies.
NOTE:- . If you use PTFE insulating tape on the sender thread when using earth
return senders, ensure you do not insulate the entire thread as this will prevent the
sender body from being earthed via the engine block.
