Hello All,
I have 1989 Lincoln Mark VII that won't start and anything related to the car key accessories switch position also doesn't work. Items like power window I believe the wiper and radio etc. I have had the battery tested (OK). Trunk light head lights and any that is on the hot battery buses works. Now the engine sound like it's going to start while turning the key but when you let go of the key she doesn't start or stay running.
Thank you for your time and help!
Todd

tab100: One post on same subject is enough - I deleted the other - too confusing with duplicates.
I guess first thing I'd do is check ign switch that is sends out power then on to relays but betting on ign switch. Most were recalled for the vintage,

Understood and welcome. It just gets confusing if a reply is made to one and bounce back and forth to see who suggested what.
While I'm here. Does key feel right? It should be pushing a rod down to ign switch which makes/enables things to get power. I would expect the items mentioned to work without ign intervention on this car anyway. As said, ign switches were trouble on many Ford products till newer and not sure what year it all was fixed and sold new with improved switches. The issue was they could short and I guess a couple fires happened and documented so all got recalled of a certain vintage/models.
Not so familiar with exactly how but you should be able to get at it by just removing some trim and use a test light. Constant power there, then when key to "run" should light another. If all looks intact and not burnt that's my suspect area for now. Others may have run across this exactly so hang in there,

Check all the fusible links coming off the starter solenoid, next to the battery. Pull on each one and if any stretch, they are burnt out. Replace any burnt ones with "fuse wire" only.

I did try working the key around a bit and I seems like it has normal play. I think you right about the ign-switch because of the lack of no accessories and reviewing the fuse and circuit breaker table in the owner guide. I have to pickup a repair manual because I not sure of the locals of a couple of fuse links for the Load Circuit (Not sure it's duties).
I just read you last thread before finishing this thread and I don't know what fusible links look like or location. Other then the locations in the owners manual.

They just look like wire that will wrinkle up and blow like a fuse,

That was me that posted that. Fusible links are special "meltaway" wire that feeds the ignition switch and they are at the starter solenoid.

I found some pictures of fusible links so I will check them. Now as far as the starter solenoid location, they are not on the starter these days? I believe the location is on the firewall.
This is the first car I have been able to work on since my 65 Pontiac Catalina. There is plenty of room for my fat hand less part to takeoff to get to the problem.
Thank again Tom for all your help!
Todd

I am not Tom and I have already told you that the solenoid is next to the battery. Just follow the positive battery cable to it.

Just looked at an 89 Town Car which may be very similar. Wires at the solenoid right near the battery as Hammer Time said had at least one black wire from a box that even I don't know what is, going into a small connector box MARKED FUSIBLE LINK! Then went on to a yellow high gauge wire and onto oblivion. Not even sure but other wires there too - look for evidence,
Tom - smile and I'm not Hammer..........

Yes Tom, You description of the small connector box sound similar to the one on the MVII. I found one fuse link but not sure if it's blow because it's rape tight between the fender and that small connector box. I just don't have anymore time today to work on the car, I will be up early tomorrow and keep everyone up to date on my progress.
Thanks
Tom and H. T.

That's why I said the wire went off into oblivion! All the connections there need be good as said.........
Good luck isolating it and where power is lost. Hopefully it will make itself apparent. As HT said (I think) only use the same to replace if found blown.
FYI - those curly plastic wiring covers with tape can be opened and put back as they are split plastic. Ford used a lot of cheap tape around then of a fabric like stuff. Good electrical tape - check grade and temp range of tape (3M 34 or 700 or 88) marked Scotch by 3M has heat rating to ~ 221F. If you splice solder the splice is always best and shrink tube over that then put it all back in place,
Tom

I think I have found the problem. I want to run this by you guys before I start to remove my steering wheel. 1st: The car turns over normally but will not run. 2nd: All accessories related to the accessories switch position do not work (radio, power windows, wipers, etc). 3nd:The radio, power windows, wipers, etc are all on different circuits and their fuses are all good. 4th:All items and accessories on (what we call in aviation) the hot battery buss work normally, power seats key-less entry trunk/hood courtesy lights etc. Your help has lead me to the ignition switch to be the root of the problem so I went to the auto parts store and looked up all replace me part relayed to the ignition switch and this is what I found.
There a $9.99 part call the Engine Management and Ignition PART #LS514 ALT PART #3528 Made by Wellstech (www.wellsVE.com and through the “Wellstech” channel at www.YouTube.com).
These are the symptoms they list is the part has failed:
- Ignition starter switch directs current from the fuse panel to other systems in the vehicle.
- When not replaced, vehicle may experience no-start, intermittent shut down and/or current will not flow to all systems.
Please tell me what you think! In mean time I will be looking for information on how to correctly remove my steering wheel to replace this part.
Thanks Todd

Have you checked the fusible links or not?

Hello HT,
I did not check all the fuse links because of additional information I received from THE LINCOLN MARK VII CLUB that stated all MK7 models older than 1990 must have their Ignition switch replace because they are faulty and may cause fires. Also I can smell a lite burnt smell near the Ignition switch.

You can't very well condemn an ignition switch if you don't even know if it's receiving power or not. Yes, all Ford had an ignition switch overload problem but that doesn't mean they all failed.

I said before the car crank over but would not run. It turns out when I removed and inspected the old Engine management and ignition module it was falling apart. Problem is solved...
Thank you for your help,

Come on Hammer Time if I listen to you, my car would be on fire in a few days! Tom pointed me to the Ignition system. Common sense tell me that Tom has a good connection on so best Lobster from Boston.

Oh really? So, you're telling me that replacing an ignition module made your windows, wipers and radio work, huh? That's a good trick.
