Yes, remove the wire hooked to the sending unit and ground the wire. Then turn on the ignition switch. If the gauge goes to full, the sending unit is bad. If it doesn't go to full, it may be a bad gauge or wiring.

I.e., send parts/car transactions and negotiations as well as other personal messages only to the intended recipient, not to the Clubhouse public address. This practice will protect your privacy, reduce the total volume of mail and fine tune the content signal to Mopar topic. Thanks!
