Engine will start by jumping the starter mounted battery cable to the starter mounted solenoid terminal.
Will not start via the ignition switch.
Under dash circuit board:
Circuit 14 is supposed to be the starter circuit. It is hot, electrified not temp, when the ignition switch is turned to the start position. Ckt 14 is a fairly small red wire. The control wire at the solenoid is a black wire, 14-10 gauge, hefty.
This leads me to believe that Ckt 14 actuates a relay or solenoid closer to the starter.
Yes, look in the passenger side bay by the engine. Open the SS doors on the inside. You should find a big Cole Hersee relay in there for the starter. It looks just like the merge solenoid except it is a intermittent duty model.
Assume your neutral light is on ? Will it start using the switch in rear panel ? On our 86 the neutral safety control is actually square relays under the dash , I will try to locate schematic.

Just a thought. Although my coach is way older than yours, I had a similar problem years ago, only the problem was the 'trigger' wire between the starter solenoid and the starter. It had developed a short. Problem solved when that wire was replaced.

On the '86 the neutral safety relays are mounted on the panel forward of the steering column about 10 inches off the floor . Almost hidden by heat/cooling hoses . There are two square plastic relays as well as a larger metal encased relay .

I had a similar problem with 385. Guys at Newell told me to get it started At rear of
Coach.....then put it in gear .....first forward then reverse...turn off at key..then try to start
It worked, they said trans didn’t know it was in neutral.
