Having problems with your Lincoln Cars & Trucks ?

How do you replace an ignition switch in a Lincoln Navigator?

\015 The starter is acting weird and kept blowing fuses. Eventually after about three fuses, the starter would keep running after the vehicle was turned off. I already replaced one starter that was doing the same thing and eventually ran itself to death. ???\015 Posted / edited by AnonymousUser on : 15-10-2018

Answers :

Don't believe it would be the ignition switch. It sounds like the starter relay may be stuck in the on position. Find the starter relay and pull it out. One terminal would be hot at all times-use a test light grounded to engine block and probe the relay terminals. Should only have one terminal showing power. Now have someone hold the key in start position. Now you should have two terminals showing power, and when key is released to the run position, the second hot terminal should stop showing power.
If it works like this, try a new relay, or a known good one. If second terminal still shows power without key being in start (cranking) position, then it may be the ignition switch or the wiring and connections between the switch and the starter relay.
You will keep burning starters out till fixed. Starters that are run more than a few seconds at a time will get too hot and burn out.
