5 amp accessory fuse is dead, ug

[elmo153]

I have a 71 New Yorker and recently lost my instrument lights and a few other small things. Traced it to my 5 amp accessory fuse has no power to either side of the fuse holder. I have wiring diagrams and see a tan wire goes to the headlight switch. One orange wire goes to a console connector ( no console ). A second orange wire goes to instrument lights and ash tray light. Where does this fuse get its power from? Please help, thanks for your time.

It derives its power not from the governed but rather from the battery.





don't mind me it's an early Friday (wink wink) and I have no idea how to answer your query.


Hope you find your answer soon.


Cheers.

Liquid lunch ??? I'm jealous. About to give up on it for the day and crack my first one of the evening.

I'm pretty sure that this fuse draws power from the light switch which means you probably have a bad resistance (dimmer) coil on the switch. A quick check would be to look on the back side of the fuse block to see if the fuse is hooked to the power bar on the fuse block. If it isn't, the fuse draws power from the light switch and the switch is probably bad. If the fuse is hooked to the power bar, most likely the rivet that holds the fuse retainer to the power strip is corroded and not making contact.

That is correct. You can try moving the dash dimmer switch a few times and sometimes they will work... sometimes not... BTW, with this car, it's a separate switch and not incorporated with the light switch. Rebuilding them is the answer if you can't get it to work.

I had mine done by this guy... I recommend him highly.

While they don't have a '71, they do have a '70 and that should be identical for most things. The wiring diagram will show how that fuse is feed.

John is right, forgot about the thumb wheel dimmer on 70/71 cars. I have one from a 1970 fury which I think is the same one. If you can get me a part number off of you switch we can check that. The unit I have is used and worked when I took it out.

Thanks Dave. You got it. The guy doing my inspection sticker must have been messing with my switch.

I had some issues with the dimmer switch before,took it out, cleaned it all up super clean and reassembled with some dielectric grease and works like new now! It's incredible how some dirty contacts influence a whole system.
