So I've checked the batteries and each are showing 11.75 volts. A little weak but should still be able to start. Again, since I bought it in October it's started strongly every time without issue so this is a real mystery.
The issue followed me removing the rear door contact and housing, verifying it was ok and then screwing it back on. When I hit the ignition that rear sensor does not sound off to indicate the door is not closed (or rather the contact isn't pressed). After that it's a real head-scratcher because I did nothing else to the bus, she just all of the sudden won't start.
Here's a video of what I get when I turn the ignition:
The center warning light is for the brakes which do have a minor issue that I'll get to. The left warning light is for the oil pressure/water temp. Then there is a "P" warning light at the bottom right which you cannot see.
If memory serves all three of these have come on in the past and never impacted it starting, but I could be wrong about the "P" warning light. I've looked through all three of my manuals, Cummins, Thomas and Freightliner and none of them indicate what the "P" warning light is for.
This is pretty frustrating because I'm sure it's something simple but I cannot put my finger on it. Any ideas what I can try next?
THANKS in advance!
