Background: 91 Ford Ranger, 351w under the hood, battery relocated to bed. Used 2 gauge jumper cables for leads when battery was relocated. Correct terminals, crimped and heat shrink wrapped. Both positive and ground running from battery to engine compartment, with a isolated terminal for the positive, and ground bolted direct to motor. Ground from motor to frame with same 2 gauge cable, and a separate short ground from the battery to the frame under the bed, with the 2 gauge cable.
Problem: Starts hard, battery must be 110% to even think about starting truck. Jump power with another battery to the positive isolated terminal in the engine bay, with the ground to the aluminum accessory drive, fires right up.
Assumptions: I'm guessing the 2 gauge cable isn't up to snuff, and I plan on buying a length of 2/0 cable to replace the positive side. I've rethought the full length ground, and plan to redo the ground from battery to frame, and from frame to motor, using the frame as the ground.

Questions:
- Should I use braided ground cables from battery to frame, and frame to motor?
- Thinking about adding additional ground straps, from motor to cab, or frame to cab. Lets assume there are no ground straps at the moment, because I can't verify what's there, and what's still good. Where should I have other paths to ground? and size?
- Changing winch solenoid to an albright style, remote mounted on the inner core support, M10000 on front bumper. What size cables should I be using? Should I run a ground just to the frame, or should I consider running a ground cable back to the battery for this?
