Ron Francis Wiring help 2 !
No, they should be tied together. Either something is mis-wired, or you have a bad ignition switch.
There are only so many "things" with the switch, but here is the general
1...you have one big main battery supply TO the switch
You have ACC which is hot both in "run" and ACC. Unless this is wired wrong, not the issue
3...You have "Ign 1" which is ONLY hot in run
4...you have "Ign 2" which is ONLY hot in "start" and originally bypassed the ballast resistor. The reason you must tie it to IGN1 is because IGN 1 goes cold in start
5..You have the START terminal which SHOULD only feed to the start relay (yellow). This may be cross wired, or you may have a problem "in the switch."
There ARE alternative ways around this problem
1....You can use the later Jeep start relay which has an extra contact and can be used to replicate the IGN2 function
2....You can parallel a second relay (Bosch) across the coil of the start relay so they come on together, and use the contacts to replicate IGN2
3....you can branch off the yellow "start" wire with an isolation diode to feed power to IGN1 during cranking.
===================================
"How to find" this problem?
I would try to figure if it's wiring, or ignition switch
Disconnect the ignition switch. Disconnect the "start" wire from the start relay. Check continuity from it to your IGN1. There should be none. (Infinity.) Check continuity from the start wire to ground. should be open. In other words the "start" wire should be one simple wire, going from the start terminal on the switch to the start terminal on the relay. With the switch and relay disconnected, that wire should go "nowhere."
Likewise, check your "IGN 2" wire. With the switch connector pulled loose, separate the IGN2 wherever it ties into the IGN1. This, again, should create one wire, separate, which goes nowhere. It should be infinity to ground and to other circuits.
