1985 Mark VII Electronic Dash Problem?

[mespock]

I have a guy that is offering me his 85' Mark VII.

Only problem with it is with the electronic dash. He has pulled it out and sent it in to be looked at and the dash was sent back with the claim that nothing is wrong with the dash.


The owner claims the dash keeps popping fuses.

Anyone have this problem? Or Know what might be causing the problem.

I can get the Mark for $1,000 with only 81,000 miles.

New Air, Tires, Tranny has new filters and fresh oil Amsoil.

Take it, its wiring. Maybe a wires loose. Never seems to be the unit unless its that computer in the center of your dash. Ding Ding Ding!

How hard is it to find the loose wire? I haven't seen this dash yet.

The car is owned by the salesman that sold me my Mark VIII.

I've been getting to know this guy he's also the Mayor of an neighboring community even smaller than Boscobel.

I'd like to pick this Mark up. I want to check on the VII's and see what to expect.

I guess you would be a good person to ask as your have a VII.

Let me know what to expect and what to look for. $1,000 with 81K.

Doesn't seem like a bad car.

I would check the digital cluster, that is the most likely culprit.

Where would this be located? I haven't seen the dash yet. So I am not sure what everything looks like. I will be looking at it in a day or so.

What I am assuming is that this would be a clust of wires connecting to a harness of some sort coming off from the instrument pannel.

That Mark will have a digital dash. It is held in by about 3 or four screws. Swap it out for a used one and see if that fixes the problem. Then you can swap the odometers to keep the mileage accurate. The odometer is a 1" white cube in the back. Good luck.

Where can you get the wire harness for the Speedometer?

I think this would be the ticket for a quicker fix.

I don't know about changing any harness. I would just swap the cluster with another, working one, and then transfer the original odometer into the new cluster.

All is fixed Thanks for the help!!

Good to hear. Was it a faulty cluster?

Yes that was what it was. The guy had everything taken out and had a new cluster to put in. Just didn't want to put it back together.

Took about hour to put it together. About 2 hours to figure how things worked.

Thanks again for the help! I have uploaded more pics.

Very cool. It's always nice when a problem irons out nicely.
