Ross - I misspoke on my first reply saying that I put power to the limit switch terminal....I meant to say I grounded them out. Grounding them did not work. I did check for voltage at that terminal but I honestly cannot remember what the result was. I'll have to check when I get home from work. Grounding out the connections in the controller box did nothing, though I don't remember grounding the pink or yellow wires.
Howard - I have no idea if the solenoids are replacements or not. They don't look new, but that doesn't necessarily mean anything. I'll grab a picture of them to check their orientation against known working ones.

You should have the full 12 volts at the top terminal. The Packard solenoid is wired just as the diagram shows. Battery voltage goes to the correct side terminal which on this solenoid is 1. That feeds both one side of the coil and the contact which closes to power the motor when the solenoid is active. When the control switch relay is relaxed the top terminal is not connected to anything but a wire so voltage can be read. When control switch relay thru the closed limit switches (or a jumper wire if limits are bypassed) grounds the wire and top terminal the voltage reading will drop to near zero and coil works to pull in the plunger..

Be careful when jumping connections as there is nothing stopping you from damaging the system by moving it beyond its range of travel. Keep the car more or less level when playing around.

For sure. Jumping across the solenoids removes the limit switches from the equation, so I left it just long enough to hear the motor turn in either direction....less than a second each.

Had a minute at lunch to check the solenoids. No power on either limit switch post. So now that leads me to believe limit switches are the problem. We did not test those yesterday.
So car will go back in the air tonight and I'll test continuity across the limit switches. My guess is that it will fail and the problem will be isolated to the switches. If they fail then I will pull back the electrical tape wrapping and check the condition of the wires to see if they are broken. Getting closer to finding the problem!

No power on either limit switch post. So now that leads me to believe limit switches are the problem. Please clarify about what post you are calling the limit switch post. Since it was a quick lunchtime test and you mention putting the car on a lift later suspect you mean top terminal on solenoids and used a voltmeter between the wire coming from limit switch connected at top terminals of solenoid and ground and got no power. If that is correct the problem is either in the power to the solenoids via the fuse and buss bar or else the solenoids are the wrong type or are hooked up with the wrong post connected to the battery buss bar. Until you find the reason there is no voltage doubt it will help to look at anything under the car. Before going under you might do more tests at the solenoids. Reverify fuse has not blown and you do have 12v at buss bar. If so, and no voltage at top terminal then disconnect or kill the power to the solenoids and do more tests with the ohmmeter function. First use the ohmmeter between the top terminal and the side terminal the battery connects to. You should read almost a direct short which would be the solenoid coil. If no continuity then check from top to other side terminal where motor is connected. If that one has continuity then the solenoid is connected incorrectly. If still no continuity then check between top terminal and ground. If that test has continuity then it is the wrong type solenoid. Be aware that if any of the tests have strange readings of less than 12v or a fairly high resistance instead of an expected almost short then completely disconnect the solenoid and try again. With other components still connected in the circuit something else in the system could provide a secondary path and affect the readings to skew the results.. In that 24046 drawing I posted earlier, if the battery is hooked up to the wrong side terminal 3 instead of 1 the voltage will never reach the coil so you would measure nothing at the top post. That would be the incorrect connection scenario. If the wrong type solenoid was used, the end of the coil is connected to ground inside the case instead of to battery. That type solenoid is the typical starter solenoid which needs a voltage to work and won't work in the TL system because the control switch does not supply any power.

Yes, the "limit switch post" I'm referring to is the upper post on the solenoid. The one that the orange/blue wires connect to from the control box. I did confirm again that I have 12V to the bus bar and that the fuses are intact and not blown. I guess it's possible that the solenoids are not original, which opens the possibility that they are either hooked up wrong or the wrong type. If I have time tonight I will disconnect the battery, disconnect all the wires from each solenoid, and then run through the tests you outlined.

So looks like solenoids were removed in the past and reinstalled backwards. I removed one of them and found that the terminal marked BATT was connected to the motor lead. Testing resistance and continuity confirmed it. Looks like all I need to do is flip both solenoids around and reconnect everything.
Sight have a chance to do that tonight, or do further testing. Got an unexpected call from someone we know to go and rescue their sons who managed to get two trucks stuck up in the mountains. So that's how I spent my evening instead.
