First, Isolate the wire on the starter that is on the "S" terminal on the solenoid, (closest to the block)
Set your DVOM for DCV, V X 50 or Auto range, put the red probe on the wire, and the black probe to a good ground, have someone turn the key to "Start"..The meter SHOULD read 12 volts.
If not, back track the wire to the Neutral Safety Switch, and do the test again, If it has 12 volts on one side but not the other, Check the adjustment of the switch, If that is good, replace the switch.. (could be on the column or at the transgression<---Misspell..But I like it so it stays..) If you have NO power to the switch...
Backtrack that to the plug at the column and isolate that wire, and measure again..If you have power on one side of the plug but not the other, check the pins and / or wires for dirty, burned or bent pins, clean and burnish the plug anyway..If you have no power on both sides of the harness plug, ...
Remove or gain access to the Switch, and isolate the "S" wire there..measure again, if no power..THEN isolate the "Hot at All Times " wire at the switch..If it has power, replace the switch..If not..
Backtrack that wire to the Solenoid "Battery" cable bolt and fuse link..check both to be sure both are hooked up and not open.
Refer to your own Drawing above..

i have a dvom now...
no, its not an automatic going where a manual is, so no nuetral safety or anything. i think the problem is with the ignition switch wiring. the previous owner had a pa system in it and i took it out... the connector had 3 wires, one which was going to the ignition spot on the fuse box. is the wire coming from the fuse box supposed to go to the ignition switch?

Get your meter fixed or borrow one before going on..
From what you say, If you put the "S" wire from the Ignition switch (which you shouldn't do..) to the battery cable, it brings the car to life..in "Start" Only..
If thats the case, the wire that goes from the battery at the solenoid to the "hot at all times" on the Ignition switch..is either not connected or has an open (fuse link) along the wire..
You need to take some voltage readings..
Is this an automatic going in where a manual came out? may have a Clutch over ride involved too.

I have a 1980 transam with a small block chevy and hei ignition with a msd ignition module. I just dropped the motor in and im getting ready to start it up and i have nothing. The battery is charged, the battery cables are good, and im sort of confused.
my dvom is broke right now so i cant do a whole lot of diagnosing. however, i took the wire that goes to the s terminal and put it to the battery, and with the key in the start position and headlights on the headlights came on so that tells me that the ignition switch, and starter solenoid are fine. My question is, when i had my pontiac motor (350 hei), i had one wire going to the s terminal and one going to the battery terminal. should i have something like the bottom diagram of the 2 below?
I know im not getting power to that wire when i have it on the s terminal but i dont understand why; it worked fine with the other motor. i have to find the wire on the other side of the ignition switch but im assuming it just goes into the main power source. i dunno, im kind of confused, and im sure im looking over something simple. please help!
