Hello and welcome. My name is ***** ***** you for visiting the site, I am reviewing your question and will reply shortly, thanks.

If you just want to see if the compressor will run, you can jump the relay from terminal #30 to #87.

The Electronic Level Control (ELC) Relay is located inside the Rear Bussed Electrical Center (BEC).

Where are terminals located.

Expert:  Jerry replied 9 months ago.

The terminals are where the relay plugs in. The #30 terminal is circuit 340 in the attached diagram and the #87 is circuit 322. (corner to corner)

Also, make sure that the #30 terminal does have power to it. Is there a problem with the ELC?
