Have a Cat 303.5E sn RKY01415 Have all the manuals it does not show a battery relay any place does anyone know if it would have one or the location? Been having problem with the battery going low and can't find any draw I know their would be some with the ECM ?

Thanks have looked through that doesn't appear cat uses a battery relay at least that what Kobelco and Hyundai called them. When you shut the key off it killed all power except for a small directly from the battery to the battery relay.
