We're having issues getting the Orion to turn on...
The + input goes to the starter battery via a switch and a 30A fuse, on 16mm² cable.
The - input goes straight to the starter battery negative.
When the Orion is not plugged in, we get 12.9V:
- between the starter battery terminals
- between the cables that go in the Orion when they're not in it.
However, as soon as we put the cables in, voltage drops to 3-4V and nothing turns on, no bluetooth signal either.
Once removed, the voltage stays at 3-4 V At between the orion + and - inputs (??) and slowly drops back down. Battery comes back up to 12.9.
With the motor running, it goes up to 14Vish unplugged, and back to 3-4V plugged.
We tested the switch and the fuse and they're still good. Any pointers on how to get it to work? Or might it be defective?
