Frequently Asked Questions

PCB:

PCB

It is the electronic brain in our system.  It takes input as electronic signals from the function senders, interprets them and then sends signals to the stepper motors driving the needles to make them move appropriately.

It takes power from your vehicle electrical system and input signals from the sender for each of the gauge functions.  Connections are made with color coded wires coming from harnesses that plug into the PCB.

Speedometers:

Speedometer

Our PCB counts up to 30,000 pulses per mile – or approximately one pulse for every 6” you travel which provides highly accurate readings.  Adjusting the speed takes only a few minutes using the thumb drive and a PC.

We can work with any brand of sending unit if it does not generate more than 30,000 pulses per mile.

Tachometers:

Tachometer

If your tach signal is less than 5 volts it will require a pull up resistor to read properly.

Yes.  We can use a signal from your coil or from your ECU – we just need to know how many pulses per revolution, so it can be programmed properly.

Fuel Level:

Fuel Level

Our PCB reads resistance from the fuel sending unit and converts that to needle movement.  If your sender – or the wiring going to our PCB – is faulty, the needle is reacting to their mixed signals.

Yes.  You will need to know – or measure – the resistance at empty and full tank.

Oil Pressure:

Oil Pressure

If you used thread seal or plumber’s tape when you installed the sending unit you may have plugged the pressure orifice or insulated the ground connection.  If that is not the problem, then you will need to check the output signal at the sender and at the PCB.

Unfortunately, no.  Our PCB reads this function in ohms, so you will need a sending unit that does that.

Water Temperature:

Water Temperature

The needle moves in reaction to the signals it gets via the PCB from the water temperature sender.  It is most likely just more sensitive than your old one and it shows as needle movement.  If you believe your water temp is constant and the needle is moving it is most likely a wiring connection interfering with the signal from the sender or from the PCB.

Our standard programming range is 160 ° – 240 ° degrees.  It can be changed if required.

Amps/Volts:

Amps/Volts

They are designed to operate on 12 volts.  Sorry, we do not have an option for 6-volt systems.

Lighting:

Lighting

Yes, we turn the lights up for our photographs, so they always appear to be bright.  However, we do offer an in-line dimmer to allow you to lower the lighting to your desired level.

Clock:

Clock

If you touch the silver button at the six o’clock position on the clock the hands will start moving.  The longer you hold the button the faster the hands move.  When you remove your finger the clock hands stop moving.

Classic Trucks wrote an article detailing the construction process on a custom instrument panel for their ’69 Ford F100.

Delivery:

Delivery

We have SuperStock instruments available in 3 different stages.  Our Ready To Ship instruments are assembled and ready for final programming and testing prior to shipment.  From the time we receive that information from you until we ship is typically no more than two working days.

For RestoFit and Full Custom Build gauges, we will work with you while quoting a cost to determine an estimated lead time.  This lead time will be determined by where you are now and where you want to end up.

Installation:

Installation

We test every instrument function in every set before we ship it to ensure proper operation.  We strongly advise you check the instruments prior to final installation to ensure nothing has been damaged in shipping as it is much easier to trouble shoot them at that time.

If your “pre-check” finds no problems and you have an issue after installation you will need to determine what happened during installation to cause the problem. We will provide as much support as possible to help you track down the source of a problem but in the worst case scenario you may have to return the instruments to us so we can determine what happened and repair them.
