My guess is that the practice of connecting recipient's ground to the chassis rather than the
negative battery post simply protects from igniting some minute leakage from the battery itself.
If instead, your
positive battery post has only one heavy red wire leading to the solenoid, but the same stud on the solenoid also has a smaller red wire (still much heavier than most of the other wire under your hood) that leads off to the fuseblock or into the wire loom, then that wire is your suspect.
The most common cause of battery explosions upon start - up is
dirty battery posts and cables, says Sam Memmolo, a master mechanic in Douglasville, Ga., and a nationally recognized automotive repair expert.
BLACK goes to GROUND [usually a metal bracket or large bolt head that's attached to the engine well sheet metal], and RED, to the positive post on the battery
Another important safety precaution is to attach the negative jumper cable for the dead battery to an unpainted metal portion of the car frame, rather than to the
negative battery post.

«It's like putting a camera inside a battery and watching what happens, as opposed to working on
a battery post mortem,» Mehdi said.
But when it comes to the really important things — how antilock brakes work, what to do if you hit a patch of wet leaves, how to clean
your battery posts — were sadly lacking.
What probably happened was that your clamps weren't making good electrical contact with
the battery posts.
If the positive
battery post has one heavy red wire leading to the starter solenoid and a smaller red wire leading to the fuseblock (or into the wire loom), then that smaller red wire is your suspected perpetrator - it may have a poor connection at either the battery post clamp or its other end, at the fuseblock.
Connect the meter leads to
the battery posts (positive with positive and negative with negative).
During the emissions part they hook up to
the battery posts.
You want as much metal - metal surface area as possible between
the battery posts and the terminals.
If you see corrosion on
the battery posts, the leads, or in the vicinity, that's why.
This will push apart the metal - metal contact at
the battery posts.
Touch one of your leads to the negative
battery post, and touch your other lead to the negative battery cable, observe the reading
Loosen the hold down nut and bolt from the negative battery cable end and remove the connector from
the battery post.
