I have a 24v battery system in a 2002 Chevy Tahoe. I want the Orion-Tr 24/12 to power 12v accessories only while the vehicle is running. The instructions say to connect the vehicle 12v switched accessory wire to the remote+ to accomplish this. That does not work. I think the instruction booklet is assuming you are running an Orion-Tr 12/XX since that would have the reference 12v ground to make use of the 12v+ ACC input on the remote+ port.
I tried connecting the 12v ground to the remote- port with the 12v+ ACC wire connected to the remote+ port. However, this immediately powers on the unit, even with the vehicle off.
How can I use a 12v switched accessory input to control an Orion-Tr 24/12? Do I need to wire up a separate relay to accomplish this?
