But it is weird for one of those to go out
No, just unfortunate - the CDI unit is part number 38770-HP5-603 @ $340 and the display is part number 37200-HP5-601 @ $195. The good news are they are still available from Honda.
That's why it's sometimes prudent to take it to a dealer for diagnosis even if you don't have them fix it, but if you take to a dealer, then they are responsible for fixing the problem if just plugging parts into doesn't fix it.
It is time consuming to check the voltages and continuity of every wire and connector, but it's usually necessary to be diligent and precise in diagnosing an electrical problem.
The more electronics are incorporated into simple mechanical devices the more expensive they become and the less user friendly they are. I have an electric scooter that was given to me because it quit working overnight - worked on day then nothing the next. The combination battery charger and motor controller failed during a charging period. The controller was $1800 and a new scooter was $2000.
Where are we going to dispose of all the electric vehicles that are scrapped? The batteries are full of toxic materials and they cannot be recycled like lead acid batteries. They have to be buried, burned or launched into oblivion to land on an uninhabited planet, asteroid or star (launch then into the sun) for disposal, but what happens when we run out of the rare earth materials to make the batteries. Oh well, that's not for my generation to worry about. My grandsons will be involved in that debacle.
