Question about 1987 Ford Thunderbird

Open Question

On a 1987 thunderbird basic with a digital speedo and analogue gauges there is a short to the digital speedo display all gauges work but not the speedo. The issue is I have found a working cluster but on the old cluster I can not find the cause of the short and before I plug-in the new cluster I would like to know the reason for the short. Now for the question: The system includes Speed sensor, computer then the cluster and work in that order correct? The gages work, the cruse control works and the car runs fine just 2 traces on the cluster going to the digital speedo are fried. Is it possible for the computer to have a short that would cause the cluster to fry? or Is it also possible for the sensor to have a short that would cause the cluster to fry? Is there a direct connection between the sensor and the cluster or is the connection between the sensor and the cluster the cars computer?

Sounds like an ignition switch problem, maybe even at the key.

SOURCE: 88 ford thunderbird the alternator shorted to

Had the same problem. Likely the fusible links. Get a Haynes manual with wiring diagram in the back (should be around $15 or so at an auto parts store). I also had to replace the air intake duct and several components of the thermactor air system. One other thought is that the new alternator is not putting out a charge, you might want to check that if you believe everything else is okay. I once replaced an alternator and the new alternator was defective. --Mark http://www.marksatterfield.com

SOURCE: speedometer, odometer, cruse control & tranny overstopped working

If it has antilock brakes, the sensor is on the top of the rear differential. This sensor usually drives the speedometer. check the sensor for an open in its windings and also the wire that connects to it for any breaks.

SOURCE: engine warning light , battery light, warning

My 04 Ford Focus the battery light keeps coming on & going off, have fitted a new alternator belt but it didn't solve the problem. The battery connections are good. Also the rev counter, speedo & mileage clock keep going haywire when the battery light is on. Do you think it is the alternator? Or is it some other common problem?

Why on my Ford Fiesta 1.4 2006 model after about driving 6kM does the analogue speedo dial stops reading and then after a couple of kM's after that the digital display goes blank?


I think you just have a failed dash display module, the whole thing is just a computer that takes info from sensors and converts it to readable analog data like speed, miles driven and so on for engine functions.

How to tell if a digital speedo is burned out on a 95 chevy impala ss


The digital speedo is repairable. The issue is, the contacts of the display are no longer making good contact with contacts on circuit board. A good gauge repair service should be able to rectify the issue. Good luck. Ron @ Speed-O-Repair.

Speedo and gauges not working


You may have to pull the speedo out of the dash far enough to ensure the plug didn't come out .
This is the car that talks to you , right? digital dash and cluster....?
I have had some come into the yard in non functioning condition only to find they had been removed to replace bulbs or whatever and not reinstalled correctly , causing a like condition.

I would certainly check the fuses first though...

Digital heater countrol and fuel gauge not working


i had the same problem in my 91 deville but the fuel gauge was intermittent at first, working most of the time then eventually it quit working all together, i also replaced my ignition switch thinking that was the issue but what actually happened is the fuel gauge shorted out the 16 volt supply from the bcm (body control module) which also feeds the ac and in my case the digital speedometer. your speedo probably isnt digital, but if you unplug the fuel gauge from the harness your ac gauge should come back on or vise versus unplug your ac and the fuel gauge should come back on right now im trying to locate fuel gauge. i hope this info is helpful to you, all you need to remove the gauge is 1/4 inch drive rachet and 7mm socket and a phillips screwdriver (#1) for the trim
