12 V electrical problem
Hello all! I have a 2009 Freedom Vision 3150 DS Class A motorhome. I believe it is the same as a Coachmen Mirada. The chassis is Ford F-53 and the manufacturer was, according to the VIN, Coachmen.....

Moving the relay to the board was the final revision to the CB-200 circuit board. The subsequent revision was to the CB-115 board. I'm not sure what designations Intellitec used on their versions of the otherwise identical BCCs. Sorry to have added confusion, instead of clarification, in my earlier replies.
This is from one of my manuals for BCC. I have a second drawing showing external relay.

Ignition Relay Functions
The vehicle ignition switch cannot carry the additional loads added by the coach.
An ignition relay, actuated by turning on the ignition key (with chassis battery
disconnect relay engaged) is provided to supply the necessary current. (refer to
figure 2 for gasoline and figure 3 for diesel ignition relay partial schematics for
details) There are 2 cases: Ignition relay mounted on the box and relay mounted
on the board.
BTW - Being a 2009, the OP's BCC will have the "ignition relay" mounted in the box.
