I do not have any cables connected. Just the battery sitting on the tray and the hold downs on. The readings are between a battery poll and a ground on the truck. There should be no connections. There are no cables attached to polls yet.
So it is not the groind cable as it it not connected to the battery. The earlier picture is for reference for the general setup cables hoowever are disconnected and i still get the 7.5 and 5.0 volt readings from the polls to a ground on truck. 12.5 volts between polls.
