Do you mean a “schematic” ? A schematic shows how components are connected.
The components are connected on a PCB.

97 grand caravan pulling a 79 starcraft tent trailer. Need to know how to add a battery and also get it to recharge while traveling down road. So as when we set up it’s charged.

ok so…glow power I’ve pretty much got…but this one is electric. LiPoly, brushless, esc. Bought an 8 channel receiver but I guess everyone figures you already know what you’re doing…no diagrams for wiring. I can guess where most of the things go, but would rather keep from frying everything. Mostly I need to know how the battery, esc, throttle hookup works. The control surfaces interface the same for either gas or electric fliers.

The exact wiring and use of relays etc. is very confusing. Different views on different web sites!!! Have just had the wiring changed on my car in readiness for a new caravan. Pin 6 (fridge) is permanently live (engine running or not) which doesn’t seem right as the battery would soon be discharged. Pin 4 is also permanently live.

My van is sometimes hopping down the road. I already paid a lot of money and had a new Cam sesor and a new Crank sensor installed. Now the mechanic tells me its a difficult wiring issue. Why not just rig a bypass? Is it possible?

A friend is installing three “Window Rattler” AC units into an old mobile home. The mobile home faces due south so the western sun hits the long side of the home, except where the awning shades it. The home is dark brown, so it can pretty warm.
He found the small AC units on sale. They are 110 AC. He wants to add a circuit for each one. Two are about 20 feet from the breaker box. I suggested that he use 12 AWG, even though 14 AWG will likely be enough. I just don’t like using 14 AWG for anything except for lights. The third unit will be about 50 feet from the breaker box. Do you think 10 AWG is needed for this one?
While I studied all this stuff in HS electrical shop, that was over 20 years ago. I have studied mostly software since then. Things have changed over the years, so I am seeking a little advice.
