I've done loads of searching, and have filled my brain with so much information about electrical systems - that I feel like I need to lay out a few of my questions and get some feedback. Please take a moment to review a few (hopefully simple) questions...
The van is a 2001 6.8L V10 with the Ford factory "heavy duty auxiliary battery" option; so I've got a starter battery - and a frame-mounted auxiliary battery.
I've procured (4) Lifeline 6v AGM batteries to wire in series/parallel, so I'll ultimately have a sizable 12v AGM bank for "house" power.
I plan to augment the vehicle/alternator charging system with (2) roof-mounted 100w solar panels (and appropriate charge controller).
I plan to keep the alternator charging system simple, by utilizing the stock relay (that's mounted to the underside of the main battery tray).
My questions are:
1) Does anyone know the specs or amperage rating of the relay/solenoid that comes with the factory auxiliary battery system?
2) Will it be able to be re-used in my electrical system, or would it be prudent to upgrade the solenoid?
Thanks in advance for your help!
