Welcome home light

Hello everyone,
I have a 2015 Bighorn 3750FL.
Recently the welcome home light fuse blew. I replaced it and it blew again immediately.
I replaced the KIB timer and the fuse blew again immediately.
Any suggestions?

Hi Beezer,

Assuming you have a control panel switch for that light, and that the light can be operated by both the switch and by the Welcome Home module, I've attached a wiring diagram that should be what you have.

If the fuse blows with the control panel switch OFF, I'd check the wiring from fuse to switch and power input to the KIB module.
