Disconnect J -AC power connector and J2-DC power connector. Mark thermocouple plugs as
follows:
• wire # 26 - mark a # on both the plug and jack.
• wire # 27 - mark a #2 on both the plug and jack.
• wire # 28 - mark a #3 on both the plug and jack.
Disconnect all plugs and connectors and lay these wires neatly on top of panel. This will help
