Core smells like it let out the magic smoke

Ticket number 132665. @Yarbo-Forum

I was finishing up my mapping of the driveway with the snow blower on Yarbo. I was getting frustrated since the drive runs weren’t going as expected. As it was getting dark and my frustration level was increasing, I sent Yarbo to charge. He went on his merry way, found the docking station, docked, and began charging.

Later that night, I was unable to connect to Yarbo through the network or through bluetooth.

I went to the charging station where Yarbo was docked and smelled “electronics smoke”.

Well that’s not good. Charging pad light was blue and there were no lights on Yarbo.

I tried the power button to try and bring Yarbo to life to no avail.

I created my ticket and sent some pictures to Yarbo Support.

I pulled the battery and hit it with my meter and it read 34.29 volts.

There was no signs of battery “expansion” or damage to the battery box or battery compartment.

I didn’t really see any char marks for areas that looked smoked.

It seems to smell worse towards the top of the core, but that just may be because smoke rises.

This evening, I spent some time cleaning Yarbo’s power board hoping to find some indication of smoke or blown electronics.

I don’t see any obvious charred marks or smoke trails. After cleaning the Power board, I do see this area of possible corrosion or water damage.

Thoughts?

I’m open to suggestions on where else to look for smoked components.

So please make suggestions.

Why don’t you have the “white goop” on the board that was sent out by Yarbo?

Ouch. Yep. Looks like water ingress to me. Fried the board. Like B-Mod said, why didn’t you install the white goop retrofit that Yarbo provided earlier in the year? They sent that stuff out to help prevent water ingress from occuring on that board.

Regardless, interesting that it happened prior to the winter months. I would have thought the water freeze/thaw cycle is what would end up causing this, not warm weather use.

I too was worried about the freeze thaw causing water ingress.

The plan was to do the cleanup of the board and apply the goop on the weekend. It didn’t make it that long.

Also received the plastic inserts that cover the boards and wires but they came too late also.

So here we are….

My plastic insert arrived today. Haven’t had time to open the box yet.

Speaking of which…. Thank you @Yarbo-Forum for sending out the replacement plastic insert! That’s great customer service!!

There’s no where else to look. That’s a new core. That’s where all the boards with the issue failed. Sorry dude, that sucks. Yarbo will make it right though.

Now, when you say, “New Core” Mister Bryan Wheeler,
how new are you talking? :thinking:

Jeepers Creepers! :face_with_spiral_eyes:

I hope my 2nd Core is safe --received only last month. :new_button:

New as in he will be getting a new (to him) replacement core. If your 2nd core has the black conformal coating on that board, you shouldn’t have anything to worry about. They also reoriented it to be raised and rear mounted vs mounted on the bottom of the core.

How does map transfer work?

In theory there is a copy in the cloud and the rest are on my dead core.

Yep, should have one in the cloud. This should help.

Hopefully you’ll get it before the tuesday snow hits your area!

Looks like I might get up to 7 inches between Saturday and Sunday. Might be my first opportunity to test the snowblower for myself. With my luck, it’ll be wet heavy snow that yarbo can’t handle!

I had 5 inches in Tuesdays forecast but it is fluctuating so much. It’s like .5 inches now. I miss all the fun!
