The VTX series are open-card controllers. A very
high proportion of controllers returned for repair have
been damaged by mishandling!
Do not let any foreign body contact the board. That
includes water, dirt, screwdrivers, nuts and bolts.
Use only fully-insulated power connectors.
The controller can be damaged by foreign body
contact if the main capacitor is still charged .
Before handling the controller or unplugging the
power or motor connections, disconnect the battery,
then leave the ignition turned on for at least one
minute before handling the controller, to discharge
the main capacitor.
Otherwise, short out the battery inputs to the
controller, to discharge the capacitor to make the
controller safe to handle.
