it seems you have a short in either one of the lights or interlock. all are connected to the same fuse. trace the wiring from the fuse box back to the component. Using a test light test in between the wires. check for any obvious breaks in the wiring.

SOURCE: alternator is not charging the
new alternators (probably a remanufactured unit) can be defective, or check the installation and make certain that all connections are installed properly and are tight. There is a large post on the back of the alternator, with the engine idling, check the voltage coming from that post-it should read at least 14 volts, anything less points to a defective alternator. Check the voltage at the battery terminals as well, it should be virtually identical to the output of the alternator, if not you have a bad connection at the battery or a defect in the wiring going from the alternator to the battery. Your ground cable from the battery to the car engine/frame should also be checked for a tight, clean connection.
