No Start after replacing dead battery
This is on my brother's 02' C32 he just bought. He let the car sit a day and a half and the battery went dead. Replaced bad battery with new one drove car 4 days just fine and he let it sit one day and it is dead again and killed the new battery.
Last night we exchanged the battery for another new one and I did a battery parasitic load test on the car it seems to be fine when I connect the meter it pulls 2 amps for 30 sec. and gradually drops down to 0.107-0.120 amperes after a total of about 1 minute 30 sec. We tried pulling fuses and none resulted in more than a .100 amp drop when it was pulling 2.0 amps.
I reconnected the battery and now the car turns over but will not catch it.
It started to go the very first time I turned it over but now it just cranks.
What is the likely culprit here or what could have been fried form having the battery die several times?
Thanks

Make sure you pull each seat module fuse....
Sounds like this to me:

If you tried jump starting the dead battery, you may have burned up the rear sam. Inspect the rear sam for any evidence of this. It may show up in form of a discoloration around where one of the fuses is inserted.

That is fancy
We figured it out no problem. When we were testing for a load we tried all the fuses and my brother put the fuel pump fuse back in the wrong slot.
So all is well for now. I had him leave everything connected and will test for a load when the battery dips again. I want to be sure it is the seats and not the overhead or sunroof since the sunroof switch half works.
Thanks to all,
