Lacroix Stormcore 100D - Not Powering On

I hope some of the Stormcore experts can help me.

I have a Stormcore 100D that won’t power on. The battery is fully charged. However, when I try to turn on the Stormcore, I get a “squirming noise” from the Stormcore and it doesn’t power-up.

The power switch lights-up white when I press the button, but all I get is a “squiking noise” from the Stormcore.

Attached is a video of what is happening.

Can someone help?

I’d try to connect via USB.

If it’s dead, I’ve got a handful for sale. Sorry, hope it’s all good.

Sensored or no? My mtb shit out omw to work one day, also 100d i unplugged my sensors once i got to work and everything worked fine, no issues since. That would be my suggestion.

I disconnected the sensors and I tried powering on via the USB - and neither solution worked.

The Stormcore is definitely getting full power (I checked the battery with a multi-meter) and the white light lights-up on the power switch (but only momentarily).

When I hit the power-on button, the Stormcore makes a “squiking noise” and it seems like it is trying to turn-on (but it doesn’t).

If anyone has any ideas on how to remedy this - please chime-in.

Thanks!!

not sure this is your fix because the noise isn’t part of the symptoms but:

did you try disconnecting the stormcore from power completely?
there’s a bug some of them had where they wouldn’t turn on if you wedged them

First thing I would do is fully unplug the motors and any extra wires and unplug the battery from the esc just keep the power button plugged in and press the power button to cycle any power that’s in the esc out than connect battery direct to the esc while not connected direct to the sentinel and see if it powers on if it does great but if it doesn’t that means there’s a fault in the antispark most likely needing a storm core replacement the best bet is replacing directly with a storm core 2.0 which is a direct swap replacement which was just made and tested by vedder and his team at vesc labs

Update: I tried everything suggested - but the 100D still will not power on.

I even pulled.the broken 100D and installed it in another LaCroix Board - and it still won’t power in.

The 100D just keeps making a “squealing” noise when I try and power it on.

That said, I think the problem is the anti-spark switch in the 100D.

Does anyone know how to fix a broken 100D?

Still have some for sale, just saying. Not many options for repair but it’s possible.
