big 3 upgrade

[stbanas]

Hey guys I'm new here and i have a 94 explorer limited. I recently bought a new high output akternator for my system and want to do the big 3 upgrade. Does anyone know where the engine block ground and the ground to the negative terminal on the battery are located? I saw the alternator charge wire already but cant find the other 2. Thanks for your help guys.

Follow the ground wire from your battery to its end thats the battery ground. I think the block ground is near the starter. I just found a bolt on the block,cleaned the area around it & ran my new ground to the same place on the frame as the battery ground. Be sure to fuse the alt wire at the battery. I run 1000 watts on a 130 alt & stock battery. It doesn't flash my lights at full volume. I have 0ga power wire & big 3. Don't mess with the factory wires just add the extra grounds & alt wire
