The two leads of the multimeter measure potential difference. A simple way to describe a voltage drop is to put the multimeter on Volts DC and touch the leads to the battery termial (either one) and the clamp around it. If everything is tight and clean (free of corrosion) the voltmeter should read 0vdc because there is no difference in voltage between the 2. If corrosion was present or the battery clamp was loose you might see a .5-1.5 voltage drop or more. Now move on from the clamp to the solenoid, Live circuits, everything intact just like it sits. If everything if correct (free of corrosion) the gauge should always read 0vdc to show that no voltage is lost. This test is better because you can use it on live circuits. To measure resistance you would need to pull the cables off and isolate them from the rest of the circuit.

Not gonna lie man I suck at anything electrical. When you say either one are you saying touch both leads to a positive or negative or just the red one to a positive pr negative? Forgive me im lost.

Never mind I got what you mean... my positive terminal on the driver side has 2. Somethin drop now what

Thanks mman those vids helped alot. I cleaned the posts and terminals snd checked the grounds for volt drop as well. It starting good and running good as of today but its still too early to tell if evrrything is ok.

I'm new to this. Just reading what everybodies talking about. I'm looking at buying a 02 7.3. With 203000 miles. Herd the engine is bullet proof. Fact or fiction?

The older pre mid year 2000 engines have stronger internals but if your not looking to crank up the power to a very aggressive level I would not worry about it. 200k miles is nothing if it has been taken care of. Check for blow-by, how it runs. Shifts. Look for excessive smoke. Good luck. The 7.3 is a good engine just do some research to find out about the trouble areas.
