Just bought this EV from finance company reselling previously leased cars; some have probably heard about these cars being sold from a ranch in Montana. Person storing the car thought it was a not running because of batteries, but it had been running 6-8 months ago reportedly.
When I received the car yesterday, the batteries were fully charged. Batteries look newer than 2008. But, car reads "Batt Err" on dash, but won't show voltage, and car doesn't run. The battery charge displays battery pack as empty. This car has an AC engine with Curtis 1238-6501 controller. First thought was that somehow the car is disabled if it thinks the batteries are too low.
Looking for solutions with the batteries not reporting voltage, near the charger under the back seat and trunk. Here is a photo of the area.
In the center of the picture between the two battery boxes, two 24 volt BMS were disconnected.
Here a close up:
and the two 24 volt chargers had 4 wires:
Then, next to the charger I found a connector with no connection:
Then I find this large green wire coming from the charger connected with only electrical tape to very small gauge white wire with black stripe. Unlikely wire combo visible in above picture also.
Charger not secured well and possibly not original charger?
If anyone has any helpful thoughts on any of this being related to battery charge display problem and no power, or other ideas that might get it running, it would be greatly appreciated.
