PAST MISTAKES


•  Connecting the KSI terminal on the controller to the 12V battery.  It must be connected to the power pack.

•  Not using the Potter-Brumfield relay to maintain high pedal protection - a safety feature.

•  Putting more than 12V across the contactor coil.  This will burn out the coil.

•  Using smaller than 2/0 cable or battery cable and poor quality lugs. This will decrease acceleration and range due to the added resistance.

•  Connecting the batteries incorrectly; typically, the lugs go on the outside of the battery terminal.

•  Locating the first and last battery beside each other; this contributes to a potentially dangerous situation.

•  Charging the battery with the DC/DC converter not isolated; this can damage the DC/DC converter.

•  Connecting the high voltage side of the DC/DC converter to the 12 V side. This will damage the DC/DC converter immediately.

•  No fuses in each circuit and no switch to turn the electrical component "on".  This is potentially dangerous.

•  Single color wiring - hard to distinguish circuits.

•  Trying to charge a 120 V battery pack with an undersize charger (e.g. 108V).

•  No gauges - how can you tell what's happening?

•  Using the auxiliary shaft instead of drive shaft to the transmission.  The drive shaft is the larger diameter.
