Grid charger just started turning on all dash as if the key on, beeps for a moment as if the ign was just switched on. This happens as soon as it's plugged in and enables the IMA fan. Doesn't matter if the grid charger's switch is on. Everything else is fine. I really don't think I just overlooked this before. Any ideas? If it was a stuck relay, I'd thing it would do this without the grid charger.
