1994 jeep cherokee lerado wont start and doesnt even turn-over. Its showing that it has 12 volts and lights and radio come on stong. Whats could be the problem?
First, try starting in neutral. If the neutral safety switch is worn out, often that will help. Next, make sure the battery terminals are clean where they make contact with the battery posts (remove and use sandpaper or whatever you have to remove any corrosion.) If your cables have replacement ends, be sure that the wires are clean under the attachment straps. Check the small trigger wire on the starter for voltage with the key turned to "start" If there is no voltage there check the starter relay in the power distribution center near the battery. (you can swap it with any relay that has the same # on top)
If there is voltage there, check the large cable. There should be 12v there at all times. Remember that grounding is just as important as the hot side of the system...make sure ground wire to the engine and to the fender is clean at it's attachment point. If the starter has proper voltage in testing, likely the starter is bad (providing engine can be turned by hand. If starter has not failed it can be due to an ignition switch failure but that does not often happen.
Never assume a battery is good because it has 12volts...internal breakdown of a cell connection can cause a disconnect under starter load. Always test with a fully charged and load tested battery.
A test light is OK for testing but using a volt meter will tell you more than just if there are volts there, it will tell you how many, often giving you a clue to bad connections.
More likely than not the battery connections are dirty, but if not, something here has to help!
