[Ovmsdev] battery drain

[Tamás Kovács]

Thanks for your answers.
No older logs, but now go back to the last main release. Today i changed
the rear bushing on my car, and disconnect the 12V battery from 7 to 15,
and after that ovms not start, only start when i create a usb connection,
now connected a power bank, but if i remove everything works.
The 12V battery is about 0.5 years old.
i think i have a problem with my OBD-ovms cable, 5-6 months ago i have a
similar problems i thing, this time i remove a Y OBD cable, but I don't
remember exactly symptoms.
