I jumped the ignition switch, started but would not continue to run.
Checked solenoid connections. Battery cable connected to large post on right, start switch connected to small post on back of solenoid, cable going to tractor connected to large post on left along with the copper grounding strap.
Hot wired from battery to coil. Tractor started and ran like it is supposed too - did not die. Problem must be from coil back to resistor. What do you fellows think?
