FR3 Four wires connected directly to coach battery?

[Geoff Ralling]

I am the new owner of a 2018 FR3 30DS. There are four wires connected directly to the positive terminal of one of the coach batteries. Anyone know if these are original and if so, what do they power? They all have inline fuse holders.

Gonna go out on a limb and say

1 Alternator
2 Starter
3 Battery Control Center
4 Battery Emergency Boost Swtch

Tnx for your reply Robo44. After posting I found a youtube video by FR on the house battery box. The fused wires are for the steps, the step lockout, the awning and the LP detector. An additional wire on the second battery is for the bunk motor. This seems to be the factory configuration.

This should be your FR3 configuration or close to it.
