No start after radio replacement
My son replaced his radio yesterday and now the jeep will not crank. He has tested the battery, alternator, and starter. He has also checked the spark plugs. He replaced the ignition switch and the jeep seems like its trying to crank but it is not turning over. He is thinking this may be related to something electrical.
He, your son, is most likely correct in thinking it is something electrical. It worked just fine before it was worked on. So most likely a fuse was blown or a wire shorted during the installation of said radio. Checking all the fuses is a safe place to start. Then move on to double checking all the work done during the radio replacement.
