Subject: GRiSO Dash After Wet Rain Ride. Sun Apr 16, 2023 11:30 am
The mighty GRiSO took me away for a few days int he last week. Some rain encountered, some dash fogging. Its happened before. Things resolve and we carry on. Not so much this time. Though will give the dash a few more days indoors int he dry to potentially dry some more.
I should have put some silicone around the edges to stop moisture getting in. But I had not. (Silly me) Any feedback most appreciated and welcome [You must be registered and logged in to see this image.]

Unfortunately sealing the surround probably wouldn't have been effective anyway as there is a vent in the back to allow access to the environment as the air pressure sensor is in there.
All I can really advise is dry it out well, first in an airing cupboard or the like, and then leave it in a box with some desiccant bags for a couple of days more.
After that reinstall it on the bike but disconnect the battery and tape the positive and negative leads together and turn the ignition on and leave it overnight. While this may sound weird and I have to say I don't really understand it the theory is that the capacitors that store enough power for assorted memory functions will discharge and the dash functions default back to some pre-determined 'Norm'.
Anyway, regardless of the hows and whys the fact is that this procedure sometimes fixes disobedient dashboards. Will it work with yours? No idea! But it's certainly worth a try.

Thanks Pete, I will do just that and see what happens. And will be sure to post an update on the future findings.
After a little google and hunting, finally got around to getting the dash apart.
It would appear the internals have had a little bath. Question now is the damage superficial and a good proper clean resolve, or it could be buggered/fried. A dash tech in Chch near home is well happy to look at it. Unless I give it a go to clean myself. Tempted to leave it to a pro though.

You could use ethanol with a stiff bristle brush - that is used commercially to clean PCBs after manufacture or repair - don't use a metal brush as it may cause more problems than you have already.
Dry well and if you don't have a cupboard or dessicant, bury it in your rice container, rice does a good job too. If the rice container is shared (like with a significant other) I would suggest a new container and a new bag of rice, else I can see this getting ugly, real quick.
You can also get spray cans of PCB coating, often called conformal coating. Can't hurt, make sure it dries for 24 hours before reassembly. Oh, put tape over any plugs or connectors, before spraying.

I took mine apart some years ago to coat it with a conformal coating and to add a desiccating ventilation system. Those fixes have worked out very well. You should try to restore all of the dash functionality using the methods described earlier. I would still recommend taking it to a dash specialist if you have one handy, even if you do restore the functionality. Moto
