Default Re: Nissan Leaf Over Voltage

Update... to clarify, the ground side of the sleep switch touched the positive of the contactor, the HV LV contactor. The Zeva was saying 73V total pack voltage and my multimeter said the same thing. A few hours later, I tried unplugging the harness from the BMS and used the multimeter again and this time it was showing 103V, which made no sense unless I created a fusion reactor. I asked PingEye3 and he suggested the multimeter was bad. I grabbed an old dash mount voltmeter I had sitting in a box and my batteries measured 55V.

So... batteries fine (thank God)... multimeter and BMS not. The bad multimeter was an unfortunate coincidence that created extra undo worry. Now just waiting for Ian to respond about fixing my BMS.
