There is a constant drain on the battery, about.

The clock is working all the time with memory functions but the display requires the ignition switch to be in the ACC or RUN position. The problem you are having now is that the relay in the MAM is being turned on as if the ignition switch is turned to ACC or RUN.

How long did you wait after turning off the ignition key and closing all doors? It can stay on from between 3 to 20 minutes depending on how long the vehicle was running.

Try waiting up to 20 minutes and see if the clock display goes off.

These are supposed to be intelligient control systems and needs time to wake up or go to sleep so only the people who designed them would understand why they have it this way. Even diagnostic procedures are lacking. They only have diagnostics procedures for what if certain component linked to system is not working and none for what to do when they fail to turn off.

If the control module is the one causing the problem, which usually are, I wonder why it is not turning off if all components linked to it is has gone to sleep.

I don't see any anything that you have missed out and it has got me rethinking. Some vehicles have the clock display on all the time and this might not be the cause of the drain. Alternatively you can try diconnecting the radio harness to test if this is the problem.

The MAM is supposed to draw only between 60 - 80 mA before going to sleep and 3 - 15 mA after it sleeps. Check the currect draw again with the new MAM and see if there are any difference as compared to the 300 mA previously recorded.

When things don't go according to plan, I would always fall back to plan B, the basics, lol.

Thats a great plan khlow2008 I too were going to suggest unplugging the radio to see how it effected the draw on the system you could have a bad radio even.

Alright keep us posted and have a happy thanksgiving

HAPPY THANKSGIVING SATURNTECH9 !

LOOKS LIKE NONE OF MY BABIES ARE BROKE RIGHT NOW. THEY SEEM TO STAY THAT WAY A LOT.I HAVE TO "STRAY", JUST TO FIND SOMETHING TO WORK ON! (IS THAT CONSIDERED "CHEATING ON THEM"?)

THE MEDIC

Hope you and your family had a wonderful Thanksgiving I know I did except had to work on. Two cars lol. Also yes thats cheating lol.

If the drain is gone with the radio out of the pic looks like you found the drain. Why dont you just put a aftermarket radio in?

Make sure you get a gm pig tail so you dont have have to cut the factory harness. They sell them cheap on amazon along with install radio adapters. Your welcome thats what were here for.

IF IT COULD HELP YOU

I USED "A124" (PROMO CODE) TODAY (4 DEC 12)---$10 off orders over $30, $25 off orders over $70, $40 off orders over $110. Online only.I DON'T KNOW WHEN IT EXPIRES

I RECENTLY PURCHASED A JEEP BATTERY. AND JUG OF WASHER FLUID TO "GET ME" OVER THE $100 MARK (A RADIATOR AND ANOTHER BATTERY LATER)

THIS PARTICULAR ONE SAVED ME THE MOST FOR MY PURCHASE AMOUNT, YOU GOTTA DO YOUR HOMEWORK TO GET THE MOST OUTTA WHATEVER YOU FIND. THIS "SYSTEM" WORKS AT AN AUTO PARTS STORE. ELECTRONICS STORES. STEAK HOUSES. USE YOUR IMAGINATION!

SINCE THEN I BOUGHT A RADIATOR--THEN ANOTHER BATTERY USING THE SAME SYSTEM---SAVED $120 TOTAL

BACK TO "NOW"

"A 124". STILL WORKS GOOD! I JUST TRIED IT ON ONE OF THESE ITEMS

."SELECT STORE" AND "PICK UP AT STORE". ALL YOU GOTTA DO IS WAIT AN HOUR. CODES DO EXPIRE. NOOOO! I TOOK IT OUT OF MY CART, YOU'RE SORTA BACK ON YOUR OWN!
