Do you have a diagram of what the painless harness should result in?
It looks like you have a heavy red cable from the battery to the starter. Then it appears you have a wire from the same positive solenoid stud through the maxi fuse to the relay. This doesn't make sense to me. The red wire from the battery to the relay should end there. Other stuff like the alternator can splice there (versus stacking at the battery terminal), but you effectively have a jumper going right from battery positive to the solenoid. Effectively you're trying to run the starter through that tiny wire, if I'm looking at your pictures correctly.
I'd remove the wire that goes from the relay to the stud on the starter. I would guess the maxi should be a "main" fuse between the battery and the relay hookup, and your alternator goes straight to the battery.
Your photo of the alternator looks correct. The big stud should go to the battery positive, often without a fuse. It wouldn't hurt to out a fuse in though, one about 1.2 times whatever your max alternator output is (65a x 1.2 = 78, Round up to 80). The two field wires should come from the regulator, and either one can be connected to either terminal IF you're using the later style regulator (you should).
Hope this helps.
