starting problem
My 73 with a 352 big block and aftermarket ignition was doing great starting with the key....i lost use of the key and was jumping the solenoid. Now i lost use of the solenoid and cannot start it at all...I have replaced the battey and the solenoid and battry cables alond with the neg cable....i still have nothing...I need help...

If you cant get anything out of the stsrter by jumping the solonoid (I.E. jump between the large terminals= 12 volts direct to starter).and you are certain all the cables are good and connected correctly, (battery is charged,grounded to the block, not the frame or body, etc.), I would pull the starter, on suspicion it is dead, and bench test it.

I agree that you should pull the starter and have that tested at the parts house but those aren't 100% accurate. to know for sure you will have to pull the starter apart and test the internal parts yourself with a DVOM. I had to do this just a couple of days ago the parts house machine passed it 7 times in a row not showing any faults but the starter was still a bad starter because the field windings had shorted to the case so the armature was getting no current.
The question I have is did you take your DVOM and do all of your volt drops before you started replacing parts? Just because a part looks bad doesn't mean its shot it can still be fine internally. Resistance tests are really only good for finding opens in a circuit because resistance in a circuit goes up when current flows so the best way to find the bad components is to do volt drops across each part i.e cables, solenoid starter to find out how much voltage it consumes to see if its excessive...for cables anything over 200mv its shot. Your starter should be the primary voltage drop.
