Only the readings amigo, only the readings.

What about 36v engines Merlyn?

Don't see many ( if any ) 36 v engines but lots of Common rail stuff circuits on 5-5volts for modules and -5 volts for oxy. sensors etc.
However you are ( intentionally or otherwise ) on the right track here mentioning voltage.
Think about other measurements in the voltage field era and see if you can apply that answer to cracking this problem.
Casting your mind back along major clue coming up.
The Wheatstone Bridge.
There, virtually told you.

I've worked with a 36v-er, and damn those batteries were heavy! (And impossible to find replacements haha)

I'll be honest, as soon as i read the way you specifically included small and 24v and 12v engines, I had a good idea where it was going. Worked with small perkins, and 2 x 36v Cats...

Good old Frank Perkins, started out with them, R6 and P6.
Still got the workshop manuals for them.
And the old smokey Cats.
So racking the old brain then re the Wheatstone Bridge clue which I remember doing in the early sixties what's the answer to it all?

BP and Revolver,

Further clues required here methinks?

This is what your first girl friend put out to you on your first date together?

It appears to me to be somewhat of a problem here engineering wise to crack this one?
As there are more than one ways of skinning a cat ( as they say ) perhaps a different angle of attack might be the way to go.
A personal approach maybe.
So I put it to you in a different format.
Winding back the old clock for me to about 1964 here I am doing my seconds exam in my fourth year of my apprenticeship.
I am going out on a date with a girl and to impress her and show her how far advanced I am I have decided to tell her all about my career and my seconds ticket exam.
As that week we have paid great attention to the Wheatstone Bridge and all it's surrounding calculations I am full of it and reel it all off the top of my head non stop.
I can see she is well impressed so I, with my underwater grease on ( Brylcreem that is, same colour and consistency anyway ) imply what a great catch I am with all this knowledge onboard .
However she tells me that since our last date when I apparently gobbed off about the Wheatstone bridge she too has done some research on it in preparation for our date and does not believe that my name really was Merlyn Ohms ( which in order to further impress her I had told her ) and subsequently tells me later in the evening when I drop her off that she is going to do a Wheatstone Bridge on me.
So what was she going to do?
It's the same answer we seek concerning measuring cyl. compressions with no dismantling but winding back your old clock in a similar situation the answer you seek should be easily obvious now.

RESISTANCE is the word applicable here.

Everyone must have encountered it in some form or another in their lives.

So Mr Ohms and that upside down circlip symbol denoting the unit of resistance is how to measure each and every cylinder compressions accurately and very quickly with no dismantling whatsoever.

But how?
