Re: SyncUp & Drive kills batteries/alternator
I picked up a SyncUp on 12/21/18 and plugged it into my 2007 Chevy Silverado. It connected no problem and appeared to be working fine. Later that day the red battery light stayed on after the truck was started. Voltage gauge showed the alternator was not charging. I removed the SyncUp but the problem persisted. I took the truck home and disconnected the negative battery terminal to reset the OBD2 system. Two hours later when I started the truck, the red battery light went out and the charging system was working fine. I repeated the scenario again today with the same result. For some reason the SyncUp shuts down the charging system of the vehicle. Obviously I am reluctant to plug it into another vehicle for fear of damage to that vehicle's charging system. Perhaps I have a defective unit or is there a problem with the programing of the unit? Does T-Mobile have any idea of what the problem is ?36Visto0likes0Comentarios
