Something popped on mine as well :smiling_face_with_tear:
Anyone have any advice for getting this back to working order? :sweat_smile:

Do I need to repair or bypass the Sentinel even if I unplug the lights/buck converter?

I have a sentinal left over from a Nazare if anyone needs one.

What is a sentinel?

The sentinel board that connects the Stormcore to the battery and it also has a converter to 12v for the lights.

Pretty cool but also :face_with_spiral_eyes: to putting all those breaking components on 1 pcb

Some please post a proto sentinel, I’ll rewire and test. Bet it’s fine.

It’s here for next time the sentinel issue raises its head.

My first time uploading an image, hopefully this works out. Photo from my current Lacroix Prototipo DSS50+. If you need better angles then lemme know!

I have more photos if needed, not sure if the first reply actually attached as a reply to your comment. I am currently checking voltages since it sat way too long and I’m worried about its health lol

This is from a Nazarene with the focbox.

Hey not sure how to respond or if you’ll get this…but I have a prototipo with the sentinel V1 in the pic and 1 of the black square chips came off when it was opened up. I found it stuck to the foam padding. I didn’t open the board it was a friends and I’m just trying to fix it bc then I can have it. It’s in pretty beat up shape but any chance you still have a sentinel laying around or know how to wire a way around. I can build a diesel motor from the ground up but I really hate electricity. But seeing as I have no means of transportation this board could be a potential life saver. Please let me know if you have one and what you would like for it. Thanks and hope you get this

Bypassing the sentinel isn’t difficult if you can’t get a new sentinel. post a good pic of what you have if you want exact instructions but basically it’s just a little soldering and maybe adding a loopkey if the focbox doesn’t turn off correctly anymore. If you are concerned about working on a live battery it can all be done as a wiring harness that plugs into the existing connectors. If you want i could make you one.

Battery goes straight to the esc
Bms/charge port/battery get connected directly
Button and receiver get plugged directly into the esc.

Adding a loopkey to the esc/battery connection if the esc doesn’t shutdown anymore

Definitely post some pics and ill bust out my crayons or someone smarter than me will chime in with better diagrams to follow step by step

Sorry I’m new to all of this. So my V1 or sentinel board is toast. I have removed it from the picture. So how do I split the power from the battery to each foc box? Do I need anything special, and how do I do the loop key to turn off the focboxes. After that I’d be good to go I think

Post a good pic of what you’re wiring looks like now, if you do the tasks for the discourse bot it ups your trust level so you can post pics but a link to an imgur or something works too

Otherwise the battery needs to connect to the esc’s but the negative goes through an xt90s as a kinda kill switch.

Then the two esc need to be connected on can. The receiver goes to one esc with ppm. The bms gets the negative from the battery and the charger port and the positive goes straight from the port to the battery

I believe this is a proto sentinel? Found it in my bucket-o-parts
