Thought of a modified 's' plan and relays to control the pumps but cant get pumps to run seperately...
Is there a name for this type of cable? I've come across the black rubber cables before but this has a grey pvc type of sheath on a rubber cable. The insulation resistance reading was just above 2 M.ohms, but the rubber conductors were in good condition. What advice should i be giving the...
