Bad cable insulation worn off touching ground?
There is no way that the positive battery terminal was ever connected to the chassis. This would be a dead short and would fry the battery. Negative to chassis is correct, but positive to chassis, no way. That positive cable goes somewhere else.
I assume you're asking how can you tell which is positive and which is negative? The red cable is positive in the black cable is negative. But if they are not color-coded the positive battery post is slightly larger than the negative battery post. If you try to connect the negative cable to the positive post it would be a tight fit and if you connect the positive cable to the negative post it would be loose.
It should be attached to the short positive battery cable.
Safe practice directs that when connecting battery cables to the battery, the positive cable should beattached first, and then the negative cable last. In disconnecting battery cables, safe practice directs cable order in the reverse, I.E., the negative cable is disconnected first, and and the positive cable last. The reason for this safety procedure is that IF the ground cable is attached first, then when using a metallic wrench to tighten the positive cable clamp, and IF the wrench in contact with the positive terminal clamp were to come in contact with any grounded metal of the vehicle, then a tremendous short circuit would occur. A massive short circuit results in massive arcing [fireball] which can severely burn a person, damage the battery [or cause it to explode], damage the vehicle electrical system, or worse, cause the vehicle to catch on fire. Always connect the negative cable last, and disconnect the negative cable first!

Only fuse would be in the PDC that bolts onto the positive battery cable.Only fuse would be in the PDC that bolts onto the positive battery cable.
Red is positive. If they are both black then the cable that is connected to ground is negative and the other cable is positive.
the red cable if there is no red cable usuallly the thicker cable is positive if that does not work look under your vehicle for the starter and fallow the thick wire back to your battery and that is you positive cable.
Red cable to positive, black cable to negative.
The negative cable actually is bolted to the engine block, and the positive cable will go to the solenoid that is attached to the radiator support. On newer models, the solenoid would be attached to the starter, and then, of course, the positive cable would connect at the solenoid down below on the starter.
On a vehicle the red is positive (+) and the black is negative (-). If they are not color coded the cable connected to the starter is positive and the cable connected to the engine or chassis is negative.
The red cable is the positive and the black cable is the negative. The positive post is slightly larger.
