The OEM gauges are air operated if I'm not mistaken. No oil involved. The problem is a dirty electrical signal coming from the SJB at startup. There is no corrosion problem either.

OEM gauges are voice coil operated and the Speedhuts use stepper motors. Dirty electrical signals don't help but haven't been proven to be the problem. Some owners still had gauge failures using Jay's power cleaning circuit. I think DBK hinted that it may be corrosion.

Kendal. I suggest you call Analogdesigner and discuss his findings after analyzing a few gauges. If you need his number let me know.
Boys! Boys!
All I was posting was that I haven't had any intermittent gauge failures since I put a smart charger on the DieHard battery.
I got rid of the Optima long ago....
But you know my gauges might fail today...

I haven't had any gauge failures since I started doing nothing. None before that either.
No such thing as gauge failure prevention.
Anecdotal experience is not evidence; it's not correlation; it's not cause and effect; it's not synchronicity. Really, it's nothing.

Ha! Well here is a fact.
My method of gauge failure protection has proven to be 100% effective. NOBODY can do better than that. And nobody can equal it any cheaper.

Then how come I don't have intermittent gauge failures any more?
The tach and fuel gauge never worked if it sat more than a week, fortunately they would work once I stopped and restarted the engine.
That shit doesn't happen now, they always work.

Everything everyone has done has proved the old Star Trek The Next Generation saying "Resistance is futile". Every suggestion made to avoid the failures work. Until they don't.

Kendal, Analogdesigner realized at a later date the fuse fix was probably not the answer. IF you have that much interest, I suggest you call him as I cannot release the data he shared with me. If you need his number, once again I offer to pm it to you. I realize you have a fix for bad gauges, but he is working on a solution to the problem.
The "intermittent" gauge problem and hard gauge failures are completely unrelated. This has been posted numerous times.
"Intermittent" gauge problems are a result of improper gauge control module to gauge initiation AT KEY ON. Essentially each gauge needs to get initialized - think of as getting an IP address assigned. If one or more gauges fails to properly initialize at key-on.... no one is going to try again that entire drive sequence so the gauge(s) will remain inoperative. Unlike the HARD GAUGE FAILURE, the cause of the intermittent gauge problem is known/understood. It will happen when battery voltage is low. Some cars are more susceptible than others. Typically, a re-start after a few minutes of running (alternator full-tilt charge), the gauges will initialize and operate correctly.
The try at a fix was not necessarily aimed at THIS problem but was thought to have some possibility to solve the HARD GAUGE FAILURE which, unfortunately, we have still seen failures. Does it help? Maybe. There's simply not enough data at all to say weather it helps and, if so, by how much.
Admittedly, it is a nice side-benefit in that it seems to have helped or fixed your intermittent problem.

I've had 2 hard failures in the past. Said enough is enough and recently had all the remaining available ones installed, functional or not. I'll certainly report back (after I have some stern words with Autometer) if any of them take a dump.
"My interest" is dealing with facts. I took exception with your post because it was stated as fact where the reality is that it is speculation... again. Plenty of new GT owners are coming on here and hopefully researching on their own and I don't think we do anyone any favors stating speculation as fact.
THE solution for all of the small diameter gauges is to purchase the replacements from AutoMeter. The new gauges use a stepper motor and, to date, there have been no known failures of these new gauges. I think it is a good fix.
For the Speedometer and Tachometer, there is no solution from AutoMeter. Owners can either purchase a new one from Ford for ~$1200 and hope they get one that won't fail - but admittedly the "new" ones are exactly the same design as the old ones, so perhaps not the best bet. Alternatively, owners can send their bad tach or speedo to us and we'll replace the innards with a new design - keeping all other attributes of the gauge, namely; gauge case, treated glass, pointer, background, etc.

I did this for my tach. Just received the unit back from Kendall. I'll be installing it this week.

Hi Guys... I'm back.. I didn't fully read all the post but I think what I did see is still no fix for the speedo or the Tach?? Unbelievable! I see the Speed Hut set going strong but I really want to keep the originals in the car. I need a new Tach! I put some miles on the car today and realized this is ridiculous going without a Tach for years now ...what the hell is going on with Ford!
