Salesman switch won't power down coach

Hi fellow RVers. I have an issue with my 2000 Amaerican Eagle Spartan chassis. The Coach disconnect wont power off and my transmission control panel stays lite up with the key off. Any help would be appreciated Thanks

If you are plugged into shore power it is normal for the coach power light to stay lit.

Sorry. Can't help on the trans panel light.

The chassis battery disconnect usually doesn't turn off all power, the engine ECU and/or transmission often stay energized. The solution is a mechanical shut off on the battery post for 100% disconnect. The fact that your transmission display stays lit speaks of further issues. Does the battery disconnect work on other chassis circuits or is it malfunctioning?

If your battery disconnect system uses a magnetic latching relay, then the disconnect switch is a 3-position DPDT (ON)off(ON) type switch, with spring return to center. Pressing it one way applies voltage to the latching relay one way, pressing the other, the other, and magnets do the switching, This is a fairly reliable system.

HOWEVER Somewhere there is a fuse, likely 5 amps. ON my Gasser, with an Intelletec BCC it's inside the BCC box (Same box houses the relays) under the "Hood" and it is on the bottom row as I recall, however..... no guarantee it is there.

Page 2: On my coach the switch failed, Oh it DISconnected just fine, but reconnecting, No joy... Pulled power off the switch (Pull fuse) and operate like 50-100 times both ways to clean switch contacts, restore fuse and if luck is your main squeeze, it just might work.

Look in the engine compartment on the left side and see if there is not a battery disconnect switch. It is about 3" across and labelled on-off.

The trans control unit (ECM or TCM whichever you want to call it) always has 12vdc power to it regardless of the disconnect. It will only wake up when it sees a 12v signal from ignition....
