Richard, thanks for the relay info, though wonder if there might be any advantage to using a relay with a diode across the contacts to perhaps extend it`s lifespan...? Similar thinking might be applied to the starter motor relay...thinking the effects of back EMF from an inductive load..?
Apologies yes, posted in a hurry
