It may be also relevant to add that the alternator output measured across the battery when the engine is running should be between 13.8V -14.2V DC. This ensures that the battery will be charged correctly. Anything less than 13.8V could mean that the battery may actually be discharging or not being charged only being maintained at current level of charge, whilst the engine is running. Anything more could lead to the battery overcharging and eventually failing

Starter Will Not Crank When Hot (Heat Soak)

The TOTAL effect of all this unwanted resistance is a dramatically reduced current flow, which in turn means the starter is limited in current, and therefore either turns very slowly or not at all. The starter solenoid is equally vulnerable to this condition, and thus may not activate the starter at all. Another overlooked contributor to “heat soak” is corroded battery cables. At some point, cleaning the battery terminals and connectors may no longer help if the corrosion has already spread throughout the length of the cables. The cable’s outer insulation “hides” the corrosion.

Problem Description

It used to be starters lasted a long time. So long they did wear out the bearings and drive assembly …and made unpleasant noises but still cranked the engine. The starter solenoid …the thing you hear that goes “click” when you have a dying battery …could also be replaced without replacing the entire starter. And starters could be rebuilt. But that was “used to be”.

Reassemble by sliding on the pinion-and-clutch assembly, the thrust collar and the jump ring. Use a small puller to draw the thrust collar back up over the jump ring. If it is one of the alternative types of collar, use a drift to tap it back on. Test that it is on far enough by measuring the armature end float movement lengthways. The maximum allowable end float is 3 mm.

The starter solenoid is a fairly simple mechanism that transmits electrical current from the battery to the starter. When you turn the key, the solenoid engages, using the electrical motor in the starter to get your engine running. If the solenoid is not functioning properly, the vehicle may not start. Determining whether the issue is the starter solenoid, the battery or the starter itself can save you time and money when repairing it yourself and seeking to have the repair work done. Start by locating the starter and work to narrow down the cause of the issue.

Checking to Find Your Jeep Starting Problem

More than likely the problem is with the transmission range switch. This is a multifunction switch. It tells the computer what gear the transmission is in, it turns on the back-up lights, and it prevents the starter from operating unless the transmission is in park or neutral.

Troubleshooting Jeep Starter Troubles

When turning the ignition key results in the starter motor not turning, this is referred to as a “no crank” issue. A “no start” issue occurs when the starter spins the engine at normal speed but the engine does not begin running. When faced with a no crank issue, it’s often not wise to immediately assume the starter is the cause of the problem.

Think of this like a crash course on the subject; a crash course that’s oriented towards making sure you know the difference between the two. That way, when you call the maintenance shop you can tell them exactly what’s going on with your car. If you can identify the difference between the two, it will make your life, and the work for your mechanic, much easier.
