Larry-
You might want to try a couple of quick diagnostics on your connections:
I assume you have a simple ohm-meter:
Step 1) Disconnect the black wire from terminal 1. This wire should feed to your wiper switch, then ground out. So on the dash, turn the switch 'on', then go and check use the ohm-meter and put one probe on the disconnected black wire, and the other probe on a good metal frame ground. You should read nearly 0 ohms. With the switch off, you should have high ohms. If you don't, you have a problem with this particular circuit - check the switch itself, and also the ground which is after the switch.
Step 2) If that connection checks out, reconnect it, and pull the big black wire. This is also a ground wire, probe test the resistance between it disconnected and the frame - should be 0 ohms again. If not, check that major ground on where it hooks to the body.
Step 3) Reconnect the big black wire, and pull the green black wire off terminal 1 again. Take a separate small wire and temporarily ground terminal 1 to the chassis. As soon as you turn on your ignition switch, I think you will get power to terminal two, and with terminal 1 grounded, your wiper should wipe. If not, you may have a bad motor, or perhaps the whole wheelbox assembly is frozen and it can't move. If in doubt, disconnect the motor from the wiper mechanism and see if it can run.
Anyway, that is probably not worded as well as it could be, but I hope it helps.
Randy.
