The Yamaha FZ V1 speedometer repair cases we receive at Gadi Garage are usually simple, but this one was different.
The FZ V1 is one of Yamaha’s early digital-meter models, and over time, the speedometer becomes weak against heat, sunlight, and water entry. Recently, a customer brought us an FZ V1 meter that had suffered extreme damage due to both water and sun exposure.
This meter had multiple failures at the same time:
- Burnt motherboard
- Water inside the meter
- Sun-faded display
- Black patches spreading across the screen
- Display unreadable in daylight
- Aged and dull outer housing
- Damaged power lines
This blog explains the complete restoration process at Gadi Garage.

How the Yamaha FZ V1 Speedometer Got Damaged
When the customer visited our Chennai workshop, he said
“Bro, the meter suddenly went off after rain.
Then the few days later it started showing black patches.
Now it’s fully dead.”
A quick inspection showed all major damage sources:
1. Water Entered Through a Weak Top Cover
The top area of the casing had become soft due to heat and age.
This gap allowed rainwater to enter the speedometer.
2. Water Reached the Motherboard
Once water touched the board, it caused:
- Circuit burning
- Rust and corrosion
- Component failure
- Shorting in power lines
3. Strong Sunlight Made the Damage Worse
Long-term UV exposure leads to:
- Full display fade
- Heat marks
- Black patches
- Very low visibility in daytime
The combination of water damage and sun fade left the meter completely non-functional.
Symptoms the Rider Faced Before the Meter Died
Before the display went fully dead, the customer noticed:
- Display turning light brown
- Patches spreading across the screen
- Faded numbers and weak visibility
- Meter turning off on road bumps
- Backlight failing
- Only the shape of the display visible, no numbers
These symptoms clearly showed internal failure.
How Gadi Garage Completed the Yamaha FZ V1 Speedometer Repair
This repair needed time and precision because both the display and motherboard were damaged.
1. Complete Meter Opening
We opened the meter carefully.
Inside, we found water stains, rust, and burnt motherboard sections.
2. Burnt Motherboard Restoration
This was the toughest part.
We repaired the board by:
- Removing burnt components
- Cleaning burnt areas
- Rebuilding damaged circuit lines
- Restoring broken solder joints
- Replacing dead parts
This brought the motherboard back to life.
3. Cleaning All Water Damage
We removed all moisture marks, rust, and dirt to prevent future short circuits.
4. Restoring the Faded and Patchy Display
The display had heavy heat marks.
We restored brightness and clarity so it becomes readable again.
5. Strengthening Power Lines and Connectors
Because the board was burnt, some lines were weak.
We reinforced them for stable performance.
6. Restoring the Outer Housing
The outer body was dull and old.
We polished and refreshed it to match the restored internal condition.
7. Waterproof and Heat Protection
We used high-grade sealing to protect the speedometer from:
- Water entry
- Heat exposure
- Long-term sunlight damage
Final Result – A Fully Working FZ V1 Speedometer
After the restoration, the speedometer became:
- Bright
- Clear
- Fully functional
- Free from black patches
- Strong and stable
- Fully waterproof
The customer was shocked that the same dead meter now looked and worked like a fresh unit.
