Got to this job after 1st tech changed selector board. Found ribbon cable in wrong. Fixed that it came down to 1 seemed fine. Called it to 2 and it shut down little above floor w e2. Changed both dz relays and no change. Checked voltages and when e2 comes on it drips one of the dz relays. Both dz relays work at 1. Anyone have troubleshooting manual for these. I have 1 page of prints. Thanks guys.
