1995 Coachmen Santara with Ford F53

My alternator isn't sending power to the chassis battery--both are new. I'm thinking there's a blown fuse or issue with the fusible link.

I've only just begun, but thus far, I have not been able to find a diagram for this engine. If anyone knows where the fuse for the alternator is, please let me know.

Thanks!

    Yes, it's 12 - 12.2, depending on where I test it.

    It's also brand new and checks out perfect at the auto parts store.

    The alternator is not getting the signal to excite it to send enough voltage. Trying to figure out why...

    Yes, the engine battery.

    Both the battery and alternator are brand new.

    The alternator checks out at auto parts store but is only putting out 12-12.2 when installed. So I need to discover what's causing this...

    Why is the alternator not sending enough power to the battery?

    If I put a charger on my battery I can keep driving. If I don't, the vehicle ends up losing power after an hour or so.

    chassis aka the engine battery ?

    is it charging the 'HOUSE' battery ? yes / no

    IF yes, check your battery combiner relay or solid state diode base battery isolator (because the alternator is working)

    IF no, might need a new alternator
