1996 Seadoo XP Gauges

[chunt]

Hey everybody, I'm new to the forum so if I leave anything out please let me know. I have a 1996 Seadoo XP. It appears my VTS and Speedometer gauge do not work at all. My multi-function gauge doesn't work. It will flash all 4 LEDs and then the battery light stays on. I have attempted to fix the circuit board myself, sadly, it is very corroded and not sure if it could be saved. I have an Electrical Engineering background with experience in circuit boards so that was my point in attempting to fix this. I have verified that 12V is at the purple and black wires. I have checked fuses in the front panel box and at the rear panel box. It appears all wires are in good health and have good continuity. I am not sure if I am missing anything or if there is something I should be looking for. Are all 3 gauges bad? What are your thoughts or advice?

The gauges go bad, it's 25 years old and corroded.
Buy good clean used ones if you can find them.

I was able to fix this by replacing the Polarizing film and resoldering some of the solder points. Works perfect now.
