Units are packed in anti-static and padded packaging so the screen arrives undamaged.

Send Us a Photo of Your Current Module — We Verify Fitment Before It Ships
Caterpillar E series backhoe loaders were fitted with more than one indicator module, and several share a similar lens and housing, so we check yours before anything leaves our facility. Send us a photo of the module you are replacing together with your machine details and we confirm the match before dispatch. Our 1–3 business day dispatch window starts from the moment we receive your photos, not from the order date. The sooner you send them, the sooner your module ships.
Please send the following after checkout:
- A clear photo of the module you are replacing, front and rear label
- The part number on that module, if it is readable
- Engine serial number (ESN) and VIN / machine serial number
- A clear photo of the machine nameplate
Installation Notes: Fitting the display is straightforward, but disconnect the battery before unplugging the old monitor, support the panel while releasing the bracket so the screen is not strained, and check the connector behind the module for corrosion or bent pins before plugging in. Clear any stored fault codes once the new display is powered up.

Common Failure Symptoms
| Symptom | What It Usually Points To |
|---|---|
| 422E or 428E warning lamps do not light during the key-on self test | No power or ground at the module, a blown fuse, or a failed unit |
| One warning lamp stays on with no fault present | Failed lamp driver in the module, or a sensor or wiring fault on that circuit |
| Display or indicator screen stays blank at key-on | No power or ground at the module, a blown fuse, or a failed unit |
| Audible alarm does not sound when a warning is active | Failed buzzer inside the module, or a lamp driver fault |
| Gauges freeze or read zero while the engine runs normally | Module has lost its signal or data link input |
| Panel flickers or resets while the machine is running | Loose connector or unstable supply voltage, or an internal fault |
| Moisture or condensation behind the lens | Seal failure and water intrusion that can corrode the board |
| Cracked or clouded lens making warnings hard to read | Physical damage or UV ageing of the polycarbonate lens |
Check the Simple Causes First: Before replacing the module, check the fuse, battery voltage and ground, and unplug and inspect the harness connector for bent pins, corrosion or moisture. These cheaper faults cause many of the same symptoms.
