Yo JuiceIsLoose,
As advised, and;
Voltage; "...a normal battery that is fully charged produces 12.6 volts, not just 12.0 V. (Remember, when measuring battery voltage, everything in the car should be off, or the battery should be disconnected. Voltage measurements are always "no load" measurements unless the battery is being tested for it's performance under load)..." by Gordon

Pinpoint Tests
NOTE: Use Rotunda Digital Volt-Ohmmeter 014-00407 or equivalent to perform electrical pinpoint tests.
PINPOINT TEST A: STARTER MOTOR CRANKS ENGINE SLOWLY OR NO CRANKING WITH RELAY/SOLENOID CLICKING OR CHATTERING
A1 CHECK CONNECTIONS AT BATTERIES
- Inspect all battery cable connections for looseness and corrosion.
Are battery connections clean and tight?
Yes | No |
---|
GO to A2. | CLEAN and TIGHTEN connections at batteries. |
A2 STARTER LOAD TEST
- Perform starter load test. Refer to Component Tests in the Diagnosis and Testing portion of this section.
Did starter pass load test?
A3 CHECK FOR EXCESSIVE RESISTANCE
- Perform voltage drop tests. Refer to Component Tests in the Diagnosis and Testing portion of this section.
Did starter circuit pass voltage drop test?
Yes | No |
---|
GO to A4. | CLEAN circuit connection as necessary. |
A4 STARTER NO-LOAD TEST
- Perform starter no-load test. Refer to Component Tests in the Diagnosis and Testing portion of this section.
Did starter pass no-load test?
Yes | No |

Slow cranking is caused by excessive engine drag. | REPAIR or REPLACE starter. |

Check both battery posts, cables, connectors & major GROUND cables for looseness and corrosion. If you see corrosion on a cables' wires strands between connectors or lugs and leading into the insulation, peel back the insulation to see how far back it reaches.

Check starter relay for looseness or rust to the inner fender. It's ground is through its body to the inner fender.
Check that starter is mounted securely and connectors are clean and tight
CHECK GROUND CABLES to frame, block etc.
Slow Cranking or a Grinding Noise; "... Problems with the negative battery cable is a major cause of starting problems in Ford, Lincoln, and Mercury vehicles. Bad battery cables can cause slow cranking or a grinding noise when trying to start an engine. ..,the wire connection inside the battery terminal connector corrodes easily. This will cause a voltage drop in the cable and result in low voltage being supplied to the starter. You can check for voltage drop in the cable using a digital voltmeter. Connect the negative probe of the voltmeter to the negative battery post (not the battery terminal connector). Then connect the positive probe to the starter case and crank the engine. The voltage reading should be less than .5 volts. A higher reading means there is resistance in the cable or the battery terminal connector. Clean the cable end and the battery terminal connector and test again. If the voltage reading is still higher than .5 volts, replace the cable and the battery terminal connector..."

Ground Location, Frame from Battery pic in a 94 5.8;
"...Frame ground just inboard of the R spring tower. The black battery wire goes from the front bolt of the engine mount (on the block) to this tab & up to the battery post, where a smaller black wire goes to the core support, providing a continuous ground path between the engine, frame, battery, & body..."
