I have a 300 amp alternator, digital battery separator and dual battery setup. After other pressing projects are finished I want to turn my attention to my power distribution/usage. I realize I'm not putting out 300 amps ALL the time NOR that I might NEVER see the full 300 amps. PRESUMABLY (IIRC can't find the paperwork and haven't had the time to contact the company) it's a 100 amp idle. What I want to do is measure what the alt is ACTUALLY putting out then what each battery is using ( obviously due to the various accessories). I have been leaning towards gauges they use in motor homes. (They will be different then my current brand I LOVE and fwonk with the overall "theme" I have and will have gauge wise but, if placed right won't look bad). I have somewhat of an electrical background and I understand that not only is AC/DC an AWESOME fwonkin' rock band they are 2 different beasts and I'm having a hard time wrapping my head around the 300 amp alt and gauges LESS then that to measure the usage/output. I think the basic principal applies that if the total draw of all devices from one battery remains LESS then what the meter reads it will be accurate and won't fry it. I also think I'll have to settle on total usage per battery or I would need a ginormous set of gauges blocking the whole windshield. As for the one to measure the alt at its "fullest" potential I guess I'm being dense/obtuse. Does anyone have this setup or thoughts of doing it OR how to. Thanks in advance.
