During this procedure, I also Routinely do Compression Testing, as well. Be sure the Engine is a OPERATING TEMPERATURE, prior to testing. Remember, on the Multi-Plug engines, remove only ONE of the plugs.

I see the need to use the circuit 30 post but didn't see any other cable connected. In this process, is there a need to connect a battery sustainer. | ||

Is the #4 cylinder the farthest from the oil pump on an m113? Thanks for the effort to make all these writeups. | ||

Soooo, you press the Trigger, it allows 12V to go from Circuit 30 post, out to the Starter Solenoid. | ||

Is the #4 cylinder the farthest from the oil pump on an m113? Thanks for the effort to make all these writeups. Supposedly, up to 1.5 Bar Variation is "Normal". To be honest, that #4 was a bit harder to press-in the Rubber cone. I probably should ha used the Screw-In method. | ||
