I can do most things mechanical on my cars but am at lost when trying to diagnose some problems using the multimeter.My question is how do you connect the multimeter to check for volts, resistance, etc.

For example, how would I connect it to check if cold start valve is functioning ok, also the water temp sensor located at rear of right side of cylinder head on my W126, 380SE. I have the W126 cd which gives the test procedures but when they say connect to this and that I can't figure out exactly how ato do it. Thanks
