Distribution Board Corrosion (ST1, ST2-Belt, ST7)

On the ST1, ST2-Belt and ST7 models, Stromer has placed the controller and the distribution board 'in frame', probably with the intention of protecting it better from moisture. Direct spray from the front wheel cannot reach the controller and the distribution board in the frame.

However, depending on the temperature difference between the battery/battery compartment and the outside air, condensation can form in the compartment in winter. As the board was not originally protected against moisture, corrosion can occur.

If the corrosion is not too advanced, it can be removed with isopropyl alcohol and a brush. Then protect the pins on the back and front with a Silicone protective varnish. The connectors and plug pins are treated with a little Electric club.

Stromer has since made improvements and newer years of the distribution board are better protected against moisture.
