So when I do a compression test I usually do it on my own, I pull the fuel pump relay first, then the starter relay so I can actuate the starter from under the hood with a jumper wire, I connect my gauge and do 3 cycles, that number is what I use.
Now the other day another guy was doing a compression test (as stated in another thread, we got tons of cars in that injested water from the flood last week) and he was cranking basically until the gauge stopped climbing......so now I wonder, have I been doing it wrong all these years? Not that it matters much since it's usually just for comparison to find a weak cylinder, but I'm curious. Whaddya you guys do?
