Hi, got one of those compression gauge but lost the instructions, how to check the compression, I plug it in the glow plug and what?

need to check my engine from Terra Crusher

thanks

now you just need to turn the engine over a couple of time to get the compression reading. I think the Terra Crusher has a ez start system so just plug it in and let it crank for a second or two then check your reading. If I remember right it should be somewhere between 45 and 60.

you can find your answer in Monster Trucks thread
