Almost impossible to say. Personally, I would start with the Final Stage Resistor. Do a search for it on here for more details. 2006 4.2 SC

Are you sure the battery is dead when your car won't start?

Start methodically pulling fuses - perhaps you can pull the one to FSR circuit to see the difference.

My 2012 car suffered a battery drain due to a fault with the fuel burning heater software when it was about 18 months old. The battery had to be recharged fully to allow the dealer to check what had caused the problem on the diagnostic system. The battery then had to be checked (over the course of the next day, presumably the test is whether it can still hold charge) to see whether the drain had ruined it. It had and the battery was replaced under warranty. Some months later the (new) battery was again drained, this time due to a fault with the locking software. Again the battery had to be recharged fully to allow the dealer to check what had caused the problem, and again the battery then had to be checked over the following day. This time the battery could still be used.

Seems odd to me why a battery would start and run then just a few hours later be dead,sounds more like a bad connection to me,check all battery,starter,alternator etc connections are clean and tight to start with. |

If your going to troubleshoot with a new battery, don't leave it connected overnight, pull it down to 7 volts a few times and it won't thank you..... Pete

Another free check is to open the boot, open the passenger side cubby hole, then shut the boot, turn off and lock the car, you will notice the GPS unit which is the top one in the boot cubby will have a red light showing if you look through the rear window... leave it for 20 mins and see if it's still on, these have given problems in the past...

Measure the voltage across each fuse and you can calculate the current based on it's resistance.
