We're learning as we go, here. Working to understand the current electrical components so we can appropriately upgrade to lithium batteries in Fozzie. Our 1986 Toyota Sunrader RV.
So.... what happen then? No more videos? Come on, man, upload them, I wanna learn too haha. This kind of videos always make my day, gathering knowledge for some future reference.
Don’t feel bad I’ve been a mechanic for almost 20 years and I always been electrical guy. I always start off same way looking at everything (building a diagram in my head) and going WTF is going on around here. 😂 it always seems daunting at first but chip away at it and you’ll get your desired outcome.
I'm only marginally conversant with watts and volts and amps as well, but looking at what you have in situ....I think you gotta pull everything and start from zero. Looking at the "connections" that include just a massive wad of electrical tape, or worse - those blue "wire-tap" things....yikes! Plus, given the amount of corrosion at the negative (I think?) post, there's probably corrosion through a decent length of those wires. So, even if it works, the power draw is going to be much greater (the poor little electrons having to fight their way thru the corrosion)...and more resistance (heat), which is not your friend. As a stop-gap, how about just plopping in one of those Bluetti (or whatever brand) power station things (e.g. Bluetti AC200L just to throw one out there). They can be charged off of alternator 12V, solar, or regular house current); LiFePO4 so it's fine with repeated deep discharge (the major downfall of lead-acid) - at 3500 (10 years, almost daily) full discharge, you should still have 80-85% of the original 2kWh that this thing comes with. Run extension cords from the A/C outlets on the power station in place of where all of the current (no pun intended) wiring resides to where you need outlets; 12V outlets on it as well for your 12V appliances. Stupid-expensive? Yes. But...either you sell this in a year or two and get back maybe 70% (certainly no worse than half) of what you paid if/when you get around to installing a bespoke solution; or you keep it as additional power (I get the sense that electrical capacity in off-grid living is like RAM and computers - there's no such thing as "too much". 😃)
So appreciate this reply here. I've looked at those portable solutions - but I do like the idea of there being a standalone system integrated and on board. But - yeah. As ever. It's a decision tree with an ever increasing number of branches.
