hi, my 90 535i has been sitting in my garage for few months.
the battery is totally dead.
since i cant access the battery under my back seats because the doors locked with double-locking, i have to charge it from the post besides my engine.
the problem is theres only positive post, the manual says connect the negative post on the lifting bracket or engine block.

but i have no idea what is lifting bracket and which part is the engine block.

thanks alot for bringing my car alive again.:)

metal loop thing for lifting the motor, or just lokk for some other chunky metal thing to ground to.

There may also be a lug on top of the strut tower. I forget which years had that. Or you can just use the unpainted strut tower studs as a negative. That's where I try and grab it.

I usually wrap a wire around a shock mount bolt- a slow charger only needs a 5 amp connection, a clean nut thread provides that with a well-wrapped wire ;)
