Look for short ground.. or trunk light, very oftend stereo cd...

my BMW was death after check around it was not the alternator or voltage regulator...

It was fue # 21 which control... stereo, glove box, trunk light, and on board cpu....

how do I Know this ... with fue # 21 on key off it drawing .04 mili amp...

when I un plug the fue number 21 amp drop to .01 that is normal for 1987 bmw


so no I have slowly remove 1 light bult at the time until I saw the amper drop than I know that where the problem is... no time do fix it yes so I run without the fues #21 it run fine..

so plug in the amp meter betwwen the (-) post and the battery cable and start to
remove your fues one by and see which one will make the amp drop .. than that is where your problem is...

good luck.. keep us post ...


but before this every one keep saying bad altarnotor.. bad rectifer, bad many thing I also replace the new battery but it do the same.. so I know it was not a battery ...
