Ok I know this is mere childs play for most here but I thought it was cool 😎
Guess the voltages for A,B, and C in each

A nice visual reminder that voltages are always in respect (or reference) to something else. In this case it was ground (common) but it does not necessarily have to be.
For bonus points:
1) what are voltages at A and C with respect to B.
2) what are voltages at B and C with respect to A.
:)
Ok I wanted to turn in my homework for bonus points but I was like wow I better do the original assignment xP
And yes I've seen the answers but it's been a while so here we go.
First I wanted to check a similar scenario on my bronco and I felt sorry for my hf meter so I verified some suspicions
Positive voltage

Negative voltage

I think I see 🙈 a trend
So here we go I filled out my worksheet and yes I was scared :loco :lmao: :grr
The way i did it in each case I started at ground then went from there

Fun fact....one time I had a 36v trolling motor for my boat and reading about and trying to figure out how to connect it and the three 12v batteries blew my mind.
:grr
Good work. Mainly I wanted to impress the idea of always asking 'from where?'
Whether you are talking about driving distance, or voltages, the point of reference should always be the first thing established.
With voltages, it is usually assumed to be 'with respect to ground', but it doesn't hurt to ask. And it's very helpful to be able to juggle the reference point around in your head when you are visualizing a circuit.

Ok I see G1 actually got me because on number two node A is at ground :dbtu:
Anyhow here are my answers

Anyhow thanks for playing I'm not kidding when I say I was intimidated by this :lmao: :loco
Now I (kinda) understand what you guys are going through when you ask someone trying to fix something to measure voltages and report back :trouble
Now the edits have rendered my question redundant. ;)
In any case, your answers in posts #2 and #4 are all correct.
