I have been having the following experiences with my D-180 which I believe incriminates the internal battery.
1. The info block on the EFIS screen sometimes shows the internal battery voltage at 14+ volts and sometimes 0.00 volts
2. With the master switch off, the unit will sometimes boot up by pushing button one -- but usually it won't. This also happens with the D-180 unit out of the plane.
3. When turning off the master switch, the D-180 will sometimes switch to the internal battery but usually will just go off.
4. The clock runs for a while and then changes to the wrong time.
Thinking this points to a bad connection to the internal battery, I removed it and checked the connection by wiring around it -- no help.
Then I put a voltmeter directly on battery -- sometimes shows 14+ volts, but usually 0.00. I have concluded that the battery is intermittently failing somewhere internally.
Anyone else have this happen?
