--> Avionics-List message posted by: "Ralph E. Capen" <recapen@earthlink.net>
Fellow listers,
Anyone out there experience a failure mode with their VM1000 internal
lighting system? The lights worked up until a few days ago...I'm trying to
remember if I have done anything to the lighting system that might cause the
failure mode sooooo........
Here's the troubleshooting that I have already done:
Pin 20 has 13.3 VDC
Pin 21 has between 4.1 VDC and 10.8 VDC depending on the dimmer setting
Pin 22 has continuity to ground
These three are 'as designed' in my opinion - so the proper stuff is at
least getting to the DPU.
Is there something that I can check on the cable between the DPU and the
display?
I've sent a note to Vision Microsystems - I'll post their response.........
