I have a bobcat T650, most of the time it struggles to start (kinda half turns over) unless I connect a jump starter to it, then it starts battery is brand new and fully charged so today I figured I'd try to fix it, I cleaned all the connections, even replaced a couple if tattered looking wires put it all together again with new battery terminal connections.... same problem battery is 100% charged and all the connections I can see are fine just to test it, I put a switched wire from where the solenoid connects to the starter to the main positive wire the as soon as I jump the switch it starts instantly, time and tima again, starts instantly but when I go back to the push button start it goes back to its half hearted tuning over again Obviously I'm missing something simple, please can someone suggest where to try next, I'm guessing there are other connections in the electrical system that actually jump the solenoid at the starter and one of these connections must be pretty weak all hints gratefully received
