As you can see from the picture above...where's R2's dome lights? Well, R2 and I drove around campus, building to building. The sidewalks were pretty rough and all the bouncing around took out the power connection. I didn't have a chance to get inside R2 to find the source of the problem. I thought a fuse took the hit or perhaps a wire popped out of the many crimp down connections that the lighting system uses.
Fast forward to now, a few weeks later...and I finally have a chance to investigate.
Turns out the slip right connection simply popped off. The DB25 connection used to stay together with friction but, well, we proved that's a bad idea!
|Disconnected! That's why the dome has no power. The dome power cable (female DB25 on left) popped off the slip ring connector (right, male DB25)|
|Put back together, now a 0.50 inch hex head screw has been threaded into each side so it stays put now!|
Using two 0.50 inch he head screws, the connectors are now bolted together.
A quick test with the multi meter shows the dome fuse block now has power. I attached the dome and the power cord into the dome fuse block. Viola! We have lighting again!
