Hello!
I bought my first bike about 5 years ago second hand and before me, the instrument cluster was tampered with Probably odometer wind-back or who knows what and after a year of riding it started to act up, i opened it up and the connection between the display and pcb was broken, so i opened it up even more to solder new wires to it. After putting it back together, i gave it some hot-glue aswell. The instrument cluster worked fine (~4 years) until a week ago when the bike was in heavy rain for a few days. The display had moisture in it, opened it up, dried it and tested it, worked again but the odometer was at zero, so something short-circuited the pcb, but still worked and i put the pcb into its casing, sealed it and let it dry for a few days.
After connecting the instrument cluster to the bike, big EP is flashing on the display, turning the iginition ON changes nothing.
Leaving the ignition to ON, disconnecting the 4-pin connector and re-connecting it, the display turns on like it should, everything works as it should. So i put the bike back togeher and went to ride, it worked until i turned the ignition off after ~40km. After that it shows me Er_1 and Er_2, also temp and fuel indicators are flashing with the ignition at OFF position, when turning the ignition on, instrument cluster works as it should and i can go ride. After leaving the bike overnight, it is flashing EP again.
The bike runs fine without the instrument cluster.
I opened the instrument cluster up to investigate, so far i have:
1. Checked the wires.
2. Checked the resistors on pcb.
3. Checked the pcb for burns or corrosion.
4. Battery seems fine.

Here's a video about the Er_1 and Er_2:

Any kind of help or suggestions are well appreciated.
Thanks for your attention.
