value of capacitors you changed on the board ?
nothing else changed ?

thanks !!!

I couldn't find a in line 0,1uF but bought a normal one, it's written + and - on it.

can I use such a capacitor and where do I put the + ? on the board or on top tp the transistor ?

thanks ;)

Given that this looks like that part of the schematic, I would put the + side towards the FET transistor , the neg side towards the resistor.
Worst case you'll have to redo in a couple of weeks/months after you blow it and do the reverse ?

I did find these 100 nF online (ebay) easily.

That part rarely if ever fails!!!!! Furthermore, the polarity of the part doesn't matter. It's not a polarized capacitor.

Normally not but he bought a polarised cap to replace that.
And mine did fail, it didn’t hold the charge very long and dropped slightly slowing down the car. replacing it fixed it.

Using a polarized cap, typically an electrolytic, will result in a marginal leakage current causing a slowing down over time,
versus a non-polarized cap (much lower leakage current versus temperature).

I know, I wouldn’t advise it. Non-polarized, radial 0.1uF is the way to go here and still easily available.

Thanks for all !
I did finally ordered non polarized one

Thanks again with all this informations
Fred ;)
