Ok so I recently bought a "new to me" 93, 4.0 Laredo to add to my 93, 4.0 Limited.
Problem: The battery reading on dash read's different but mostly 10amps rather than the norm of 14, It would start all the time with no delay. Today however, for some odd reason I have power (lights) but no sound or click when I try to turn it over. The previous owner installed an alarm system to bypass the standard Jeep alarm. I thought the alarm was draining the battery so I pulled the alarm, replaced the negative terminal and checked the ground to the altenator and body (all seems clear).
I'm doing some late research before I pull the starter tomorrow morning.
Please help, I'm not very good with electrical....
I usually have 10 volts when my car is off. Mine just takes longer to turn over, and I don't have an alarm. Depending on how long your vehicle sits for, you can remove the Ignition-Off-Draw fuse to stop it from drawing battery. I would try this first, but just as a note, your alarm system and power locks may be inoperable. You should still be able to open the car manually with the key, so I would try to keep an eye on your car if you usually alarm it.
I don't know all of the things powered by the IOD fuse, so I would look around the Internet and see before trying it.
My reference is to the manual (I have 1 yr newer). Under Maintenance, under Vehicle Storage.

The alarm never interfered with starting and the unlock still works (lock never worked). I don't have a volt meter but plan to hit Advance to replace the battery and test the starter and altenator. I'm kinda tight with the guys up there so I'm going to see if I can borrow their's or a neighbor's.
NOTE: I have a battery charger, when I hook up the battery charger it's supposed to act like a jump and I still don't get a reaction (no click, no crank)
What reaction would I get by wiggling the big cables
Because sometimes they get corrosion in the terminals or under the jacket where you cant see it. Moving them around sometimes will make an intermittent connection to carry more load and the engine will start.
What you are describing sounds like the main battery terminal is corroded inside the crimp connection. I say this because you have low voltage everywhere.
Also suspect the ground connection on the right fender by the battery, and the ground under the alternator on the block
