It looks like there is one coming off of the engine/trans-axle on the bottom. I have included a Technical Service Bulletin(TSB) on how to check your electrical system using a voltage drop test. Voltage drop testing is the preferred method of electrical testing for automobiles. It's fairly simple and a lot more accurate especially in finding unwanted resistance, which is what we are looking for here. To do this voltage drop testing, take your multi-meter and place it in DC voltage mode on the 20 volts setting. You will be doing this on a "live" circuit so you will need to start your vehicle. With your vehicle running, you measure the voltage between two points in the circuit, i.E. The ground strap from the engine block to the negative battery terminal. As a rule of thumb you do not want to have more than 0.1 volts in any part of the circuit, except across the circuits load, where you want all available voltage to be dropped. Any readings more than 0.1 volts and you have unwanted resistance in the part of the circuit, i.E. A corroded ground connection, frayed wire, etc. Look in the diagrams below for the TSB.
