Question about 1966 Ford Mustang

The gauges have stopped working ? Fuse under dash seems to be OK ?

I have recently switched out the ignition system (plugs in) and now the gauges have all stopped working. I check the fuses (under the dash) and they all seem fine ? I'm stuck ! No Fuel, Oil, Amps or temp gauges working?
Help !

Behind the dash is what they call a constant voltage regulator. It controls the guages. It's small and located behind the dash near speedo.

    Does the 1988 300ZX have the same constant voltage regulator? If so, where is it located and what does it look like?

Nissan avenir dash lights


There is a fuse for the warning lights and gauges. Yes, you checked the fuses and relays, but you need to check if power is there at the fuse, with the key in the on position.

Here's how turning the key to on causes the warning lights and gauges to turn on: From your ignition switch the on or run wire out of it will have power with key on. The run wire will also send power to the part of the fuse panel that is of the category "hot in run or on", where your fuse for the dash warn. lts. & gauges is- it may be labeled "meter" or "gauges" or like that. From the fuse, a hot wire goes into the harness for the instrument cluster-for the warning lights and gauges. The wire, like the fuse, is only hot in on or run.

The ignition's run wire may splice with a direct connection to some fuses, or more likely there may be an "ignition relay" that powers the "hot in run or on" fuses, and the run wire is used to turn the relay on. You could look for this relay just above or around the fuse panel under the dash. But the easiest place to start is to see if the fuse for the gauges has power to it with the key in on. If it does, the problem is up further on at the cluster connection or a ground for the gauges and cluster. If the fuse has no power available, then the problem is between the ignition switch and the fuse panel. That could be a faulty ignition relay.

Dashboard gauges turn off and on


A bad connection could be it, possibly a failing relay. One would have to pull some paneling off, possibly the steering wheel covers, to start looking for the problem.
Coming out of the ignition switch will be a start wire, an accessory wire, and a run wire. The run wire is for both the ignition system and for the gauges and warning lights. One splice of this run wire will go to the fuse panel, to power up those fuses that are termed "hot in run or accessory". Or sometimes, the run wire energizes a relay that sends power to the fuse panel. One of these fuses will be for the gauges and warning lights in the dash.
If you have a test light or voltmeter, you could check the fuse terminals for power at those times when the gauges are not working. If the fuse terminal shows no power when the key is on, then the problem is between the ignition switch and the fuse panel. This could be a relay that is not working- probably called an ignition relay-and it may be right around the fuse panel. If the fuse terminals do have power when key is on, but gauges are not working, the problem is between the fuse panel and the dash-will probably need to pull the dash cluster out to look further-possibly the electrical connector or connections at the cluster. If you wiggle the wiring around the fuse panel and the ignition switch and see the gauges move (key on), then you are wiggling a bad connection and can find and fix it.

Instrument panel went dead


Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

TOYOTA fuel and temperature gauge


Some cars have a second fuse box under the hood near the battery. See if your car doesn't have one of those.

I had the same problem recently but replacing the ignition Coil under the distributor (inside) solved the problem. Also replaced the distributor Cap and rotor at the same time.
