I try not to just throw parts at my mechanical possessions. Trouble shooting this is not nearly a full time effort. Cables all around are 3 years old. All heavy wires are 6 awg. They have been upgraded from stock. Not sure if CC ran a wire from the Neg of the battery to the Frame very close to the engine but I did. I just unbolted and cleaned those connections
Throwing a new starter in, from what I've been reading is not 'just throw a starter in it' Not to mention a kohler Starter is close to $200. Of course there are $50 Starters out there but I am leery of buying one of those that will fail in a month. Brushes range from $20 to $60. Again, no big deal to throw in a set of Brushes IF you can get the Starter out of this opposed twin. Grounding thru the Mounts.. That should be solid. I did run Jumper cables from Neg on battery to Intake manifold to insure good Return Path. Then I Jumped across the solenoid to eliminate Carboned up internal contacts. Didn't help anything. Tried a known good NAPA H-12 battery. My battery is a 3 month old U1R. At this point the Starter is left.
