10189242Through our ongoing testing we determined that a small amount of Alta Redshift 5.8 Battery packs was produced with a potentially faulty component. While there is no safety risk, if this component was to fail, there is a small chance the Redshift might become inoperable. A Redshift with this faulty component will occasionally show a "precharge timeout" or "precharge fail" fault message on the display. Cycling the key a few times (up to 20) should clear the faults temporarily, allowing the rider to go back to camp.
10189241Skidframe Inspection
10189240With data from field testing we found that the small wiring harness that connects the Charge Port connector (where the charger?s plug is inserted into the bike) and the Direct Current Charge Port (DCCP) might have the ability to wick water from the Charge Port connector down to the DCCP. In this case moisture in the connecrtor is causing a "short" that the Redshift's ECU could sense. This will cause the Redshift to not accept a charge.
10189239Through our ongoing testing we have determined that a small amount of Alta Redshift 5.8 Battery packs were produced in such a way that an individual connection between cells might fail. If this failure happens, a loss of overall charge and overall power might be noticed. The machine wouldn?t necessarily throw a fault warning nor would it stop providing forward motion. It is plausible that a customer could be riding the bike and not even notice that this failure mode has occurred.
10189238Through ongoing testing, Alta has discovered that off-bike chargers shipped with 2017 Redshift MX (VINs below) can exceed the current rating of a standard 15A 120VAC outlet as found in many homes. Exceeding the current rating of the outlet may cause the building wiring or plug to overheat, potentially leading to a fire.
