OK, in the past week, I have been going through some issues with Sears regarding my battery. I bought it about 9 months ago andI've been having problems starting my car lately since I almost drained it on Halloween. Seems logical... but here is the wierd part.

The past 3 times I have disconnected my negative terminal to reset my computer... nothing resets. All of my stereo presets, clock, everything are all fine. This has never happened before. I chalked it up to the terminal only being off for a few seconds. The 2nd time it was off was ata Sears... maybe 2 minutes. Connected it and all my presets stayed the same. Once is odd, twice is very strange. Now... yesterday I was at Sears AGAIN (4 day in a row) and they finally agreed to give me a new battery under warranty. They disconnected the old one, went inside, came out like 5 minutes later with a new one. They put it in the truck, then like 10 minutes later, connected it. Now... BOTH terminals had been off for like 20 minutes. I fire up the truck... presets are all fine. NOTHING has been reset as if there was never a loss of power at all. How is this possible? Is something greater wrong with my truck? Help.

 

I don't know if this really works or not but I have heard to take both terminals and tape them together for 5-10 min and then connect them to your battery it's worth a shot to see if it my reset everything for ya. But yeah sounds weird should work with just neg cable disconected.

 

just pull the efi fuse instead of the battery cables...it will reset the ecu...if you have an aftermarket radio some of them can hold memory without any power hooked up

 

I'm pretty sure its your Capacitor from your sound system if you still got it, thats give some juice to retain the memory of the clock and cd player.

 

If you have a capacitor on your stereo, that could be doing it. After you disconnect the battery, you need to discharge the capacitor. I typically use a 12V bulb (like the ones for blinkers, brake lights, etc.) and solder two wires to the terminals. I then solder some aligator clips to the ends of the wires. clip one to the positive battery cable, the other to ground. It should only take a few seconds....you will see the lightbulb light up then go dim and finally die.

 

That might be it... it's just strange how sometimes when disconnecting the battery, it will rest things and other times it won't. I have already pulled the EFI fuse when we did the tune-up, so the computer should be cleared. I was just hoping that there was nothing else wrong with the truck. That's all. Sounds like all is fine then I guess.
