I am having problems booting up - works fine in the house, but hit and miss in the car - My power supply is at 10a and 13.8 to 14v, the car is teetering around 13.5v. if it gets up to 13.8, it seems to boot up. Is there a way to adjust the power supply to accept this lower voltage ? - It's the only scenario that makes sense. My last vehicle did the same thing and I was hoping a new vehicle would fix it, but no. Must be something in the power supply.

Thanks for any help !
