|The solar panel creates approx 27v of electric during the day light, even if there is very little sunlight or a cloudy day.
That electical current is routed from the solar panel on the roof down through the C PILLAR in the same harness as the Air Bag wiring.
After shutting down the 12v ('READY' indicator) the 27volts created by the solar panel is still LIVE traveling down through the harness in the C PILLAR as long as sun light is hitting the solar panel.
Be aware, that if you were to cut through the C PILLAR in an attempt to remove the roof, there's an arc potential there to be concerned with which could very well jump accross or short out the Air Bag wiring thus deploying the Air Bags.
There are 2 solutions to this issue:
Once either of those procedures are done you will have shut down all electrical flow in the C PILLAR instantly.
