Before checking the starter, you should verify your primary wiring. IE, the heavy black ground connection to the (-) side of the battery, and the heavy red connection from the battery (+) to the starter.
Start by (pun intended) putting a voltmeter on the battery- directly on the battery posts. Verify 12 to 12.5VDC. Then have someone crank the starter.
- If the voltage stays about the same on the battery, then you probably have a bad connection.
- If the voltage drops substantially (say down to 10VDC or below), then your connections are good but the starter is lugging.
If a bad connection, then you have to find it. If its at the battery itself, you may see one of the terminals smoking a little or even hot to the touch. You want to remove, clean, and then tighten all connections- at the battery, at the engine ground, and at the starter.
Once the car starts, the battery voltage should be in the range of 13.5 - 14.5 VDC. My 96 has a 70A alternator with solid state regulator and runs at 14.8 VDC. My Sonett has the standard 35A alternator with relay style regulator and it runs at 14.5 VDC.
If it is the starter, then changing it out isn't too hard- but enough of a pain that you want to make sure that's the problem before removal.
