Question about Cars & Trucks
New starter switch. New battery. New starter. Im thinking bad ground. No meter to test with.
Haven't work on one these but following is what I use for finding bad grounds even though I got several meters.
You can rig up test light using some wire and a 6 v lamp bulb. It won't give an exact voltage readings but a brightly lit lamp indicates at the present of the voltage.
For testing for bad grounds use the main battery ground connection and probe the ground connections around the starter while trying to start. The test light will make it safer as you are just looking for a lit lamp will trying to start; just place the lamp where you can see it from the starting position. The test light will light if there is a bad connection between the starter's ground and the battery ground.
The same setup can be uses to probe to see if voltage is even reaching the starter through the switch and solenoid connections. If the starter solenoid is separate from the starter it can have a bad ground too and will not operate.

Tapping the starter does not always work. I would check all the connections on the battery and starter. If these are good replace the starter. Don't forget the grounds.

I had same problem w/ my '88 Ram50. Turned out to be bad contacts on the battery cables. Temp fix and test was to put a little screw between the post and the end connector. Didn't have a problem then, so I replaced the cables.

start at the coil with dvom or test light to see if there is power to the coil when you turn the key on and the power should be there during cranking the best way is the dvom when you check battery voltage with digital volt meter at the battery record that amount then check the red wire at the coil should be 0.50 volts within battery recorded voltage if its allot less check voltage at ign switch should read real close to battery voltage this is called battery voltage drop testing if you google voltage drop testing it will exsplain further. i hope this helps Thunderboltz.
