The voltage at the 12v terminals was 11.2v and kept dropping. P.S. There is nothing mysterious about the ISA 215 board, just the usual degradation of ferrite in transformers with decreasing transformer ratio. I've seen this in switching power supplies and in galvanic isolation of welding machines.

I checked the voltage of the 12v battery in ready mode and when charging the HV battery from a 240v mains supply, the 12v battery only discharged.

Hello. Almost all components on the ISA 215 board have been replaced with new ones, but it didn't help. After installing a 2Mom resistor, the car started to go into ready mode. The first test drive lasted 10 minutes and everything was fine, but after the second attempt after 5 minutes I got a...

Hello. After connection launch i see more problems. No change 12v battery, no balance cells. This is the first trip after repairing the error P1A15.

Hello. After 5mins of driving the error p1a32 appears, ready mode is not available. After 10 minutes it starts and drives but less time.
