SOURCE: i have a wiring question. i have a generac 5522
The generators control board senses lost utility (N1 & N2) and after a time delay kicks in the backup. The board sends 12 v to the transfer relay thru wire 194 then back to terminal 23. This is held open till the startup timer times out and only after the warmup does wire 23 close to ground. This energizes the transfer relay, contacts close and E1 & E2 can now conduct generator produced electric to the transfer relay contacts, limit switch (XB1), Wire B, and a bridge rectifier.
