Dave Kriedeman Posted March 13, 2016 Report Share Posted March 13, 2016 Hi,you need to back trace the circuits that are staying live with the ignition turned off.Normally there will be a relay or relays that have the coil power side of the relay have 12 volts applied at all times.This pin on the relay needs to be made active (HIGH) 12 volts positive only when the ignition is turned on.This is the most common fault / cause of the problem.RegardsDave.
