Note that starters can and do sometimes develop intermittent faults due to bad spots on the armature. The bottom line is if there is battery voltage to the starter (and no excessive voltage drop) and yet the starter doesn’t work, it’s dead.

What happens when there is no power in a jeep?
If there is no power, then the electrical circuit supplying the motor has a fault. That circuit begins at the battery and includes grounds, wiring (some of which is very heavy cabling), fuses, relays, the ignition switch and terminations.
What to do if there is no starter motor?
If there is no starter motor operation at all, that is if there is no starter operation with the key held in the “start” position, the procedure is to test for power to the starter motor. If there is no power, then the electrical circuit supplying the motor has a fault.
Why does my Jeep not start when there is no power?
There is a wire that goes to the power distribution box on the finder close to the battery, if you don’t have power to it nothing will work. Could be a dirty connection there or there is also a large main fuse in the PDB that supplies power to all circuits in the jeep. I would check the fuse box for problems.
What happens when the starter doesn’t work?
Basically, with a fully charged battery, and with the key held in the “start” position, the starter is either getting power or it isn’t. With the key in the “start” position, if the starter motor is getting power but the starter doesn’t work, then the starter is condemned and replaced.
Is the starter relay the same on a Jeep Wrangler?
The 5 relays in the box are all the same part number, I’ve swapped out the horn and the ASD relays with the starter relay and nothing changes. Horn still works with the other relay, etc. The control side of the starter relay is just never getting grounded, which is controlled by the PCM.
How can I tell if my Jeep Wrangler battery is dead?
Well, the most effective is to hook up a voltmeter and take a reading under the load setting. The first starting point when diagnosing a dead battery is to verify your battery has the correct voltage. Incorrect or low power to the starter will not start your Jeep. Batteries use CCA (Cold Cranking Amps) to measure starting power.
