That sounds just about right, if the relay contacts get welded together it sometimes takes out the driver on the printed circuit board. As you found out, 12vdc from 23 to 194 makes the transfer switch move to the Generator position, relay not energized makes the ATS move to the Normal position.

You can make a nice test function by installing a 10 amp contact switch in series with either the N1 or N2 terminals. When the switch is open the generator thinks the Normal power has failed.

Regards,
Carl

SOURCE: Generac 4456 does not start on power loss

I install and work on these everyday. If you hooked up the transfer switch you probable have a control wire wrong. check the utility power sense wire. That lets it no when to start in auto. it could be a relay or fuses. or a control board.

SOURCE: I bought a Generac 17kw with automatic transfer

If you are using a Manual transfer switch, then you should manually operate the system. Why don't you use the switch it came with? Why would you use a 200a manual transfer switch on a 17kw generator? The idea is to move your critical circuits into the transfer switch panel. Then it would operate in auto.

SOURCE: I Am installing a Generac 20Kw air cooled unit

It is always good to install a large enough wire where the maximum load can be drawn plus a little extra for safety. 7 gauge wire will do, if it was mine I would use 6 gauge wire. If the length is over 20 feet but not longer than 80 feet go to the next larger size wire.

Sounds like the electritian wired something wrong. Control wiring for that generator should be:
N1 and N2 = 240 vac utility input
Wire 0 = ground
Wire 194 (15B) = + battery
wire 23 = transfer signal
