FAQ

Q) What size are the gauges?
A) Minor gauges are 52mm and Major gauges are 80mm. (SAAS)

SAAS Muscle Series :

*As long as your gauges fall within the specified range, they’ll fit the dash kit. For example, if your minor gauge bezel measures between 8.5mm and 9.5mm, you’re good to go.

Q) What’s the difference between SAAS Muscle Series 1 , Muscle Series 3, And Muscle Digital?

Look:

• Series 1:
  The Muscle Series 1 is traditional analogue-looking gauges. There are some subtle differences between them, and even more differences under the hood. The Series 1 has clear needles and a gun metal bezel.

• Muscle Series 3:
  Muscle Series 3 is traditional analogue-looking gauges. There are some subtle differences between them, and even more differences under the hood. The Series 3 has red needles and a bright aluminum bezel.

• Muscle Digital
  The Digital gauges are obviously unique. They have a digital readout, plus an analogue progress bar around the perimeter of the dial face. With a grey bezel

Colours:

• Muscle Series 1:
  Series 1 can be set to Green, Red, Blue and White.
  
  *Note that the minor gauges lose their colour setting when the battery is removed, and default to green.

• Muscle Series 3:
  Series 3 can be set to Red, Green, Blue, Purple, White, Amber, Pink, Ice blue, Orange, and Aqua.

• Muscle Digital:
  Digital can be set to Red, Green, Blue, Purple, White, Amber, Pink, Ice blue, Orange, and Aqua.

Features:

• Muscle Series 1:
  Speedo and tach have a remote programing button, while the minor gauges have a programing button on the rear.

• Muscle Series 3:
  Speedo and tach have a remote programing button, while the minor gauges have a programing button on the rear, and an optional remote programming button (supplied).

• Muscle Digital:
  Speedo and tach have a remote programing button, while the minor gauges have a programing button on the rear, and an optional remote programming button (supplied).
  
  

Sensors:

• Muscle Series 1:
  oil pressure and water temperature sensors are single wire.

• Muscle Series 3:
  Oiil pressure sensor is 3 wire, and water temperature is a 2 wire sensor.

• Muscle Digital:
  Oiil pressure sensor is 3 wire, and water temperature is a 2 wire sensor.

In summary, the Series 1 and 3 are visibly similar, while the Digital and Series 3 are electronically similar.

Electrical Interference & Gauge Readings

(Important for Older Vehicles)

SAAS electronic gauges are designed to be accurate and responsive, but like most modern electronics, they can be affected by electrical interference—especially in older vehicles that weren’t built with sensitive electronics in mind. If the wiring isn’t set up correctly, you may notice unstable readings, flickering displays, or the gauge restarting itself.

These issues are most commonly caused by electrical interference entering the sender wiring. Oil pressure and water temperature gauges use low-voltage signals, which means they can be easily affected by nearby electrical activity.

Common sources of interference include ignition components, alternators, electric motors (such as radiator fans, fuel pumps, or wipers), relays switching on and off, and poor or corroded ground connections.

Common Installation Causes

• Using different ground points for the gauge, sender, and accessories, which can allow interference to travel through the wiring.

• Running sender wires too close to ignition wiring, coils, or alternator cables.

• Powering the gauge from an old or unfiltered ignition circuit.

How to Avoid Issues

• Use a fused ignition-switched power supply.

• For best results, power the gauge through a relay directly from the battery.

• Avoid tapping into heavily loaded or aging circuits.

• Keep sender wires away from high-current wiring.

• If wires must cross, cross them at right angles rather than running them alongside each other.

• Use suppression-type spark plug leads and ensure ignition components are in good condition.

Following these steps will help ensure stable readings, smooth operation, and long-term reliability of your gauges.
