WFCO error code Yellow (amber) AC input LED on
Power-center AC input voltage indicator: the incoming AC is below 105 VAC (low line). Green would mean 105 to 130 VAC normal. The manual's instruction is to shut down the power center and investigate the cause. On the WF-9500-AD the manual captions the LED figure 'Legacy product only- not in latest model', so a current 9500 may not carry these LEDs.
What to check, and in what order, is in the app. The flow WFCO Auto-Detect converter / power center - no DC output or battery not charging (WF-9800-AD, 8500-AD, 8700-AD, 9500-AD) walks this code step by step with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
