Thank you Sylvain for this new possibility of contacts!

Thank you very much Azzuro,

I could test this diag mode as soon as I have received the fuses to be replaced on the MC board and reinstalled everything. I will keep you informed as soon as possible...

Beautiful day, (here it’s rain and snow since this morning in Savoie)

Well, I have only 4 Hex files download from the site https://vectrixparts.userecho.com/

MCR2042-4.hex

EVPS LiMn 36s-2.hex

DIY_1708.hex

BMS R64 9cell.hex

I’m sorry, next time I would import smaller photos

Hello Azzuro,

Thank you for your analysis. I am sending you pictures of the BMS cards, the installed pack, the labels on the MC, as well as a screenshot of the diagnostic tool that must read the software versions (if this is indeed the case).

I extracted the MC board and found a fuse out of order. (on the picture) I started doing reference searches equivalent to T 40A 250V and it’s not easy to find a reference that can match.

Hello,

After buying a scooter in a running condition but with a charger out of order, I replaced the batteries and the charger, but I now have a sudden acceleration defect. Could you help me please? I have added the history below:

phase 1: scooter purchase

scooter from 12/02/2010, lithium MPtech model

defective charger 1004061 V19NFD

- replacement of batteries from elements of the latest generation Nissan Leaf

---> rolling test OK

phase 2: purchase of the replacement charger April 2025

model: 1004251 gold-colored case

previously installed on a lithium model,

- installation of the charger

---> impossible to start

recovery of the original charger CPU card 1004061 V19NFD + identical modification

--> start OK, charge OK

---> but 2 problems noted:

1 - when the charger is connected (via J3) at some point, the key lights up on the dashboard, but no error when connecting the diagnostic program

2 - at acceleration depending on the position of the wheel, nothing happens, or the engine growls without moving. Just turn the wheel a little so that the acceleration is normal.

Do the software versions need to be updated?

Currently:

Other information from the diagnostic tool:

I agree :) !

Following a connection error ( 230VAC on the signal input) the transistor, 2 CMS resistors and copper tracks burned.

correction : 230VAC from filter
