Had a TH feeder where the timer just showed dashes on the display. Changed the battery for a known good one. No change. Sent the timer to Cody for replacement, he looked at it and said it was good. He sent the timer back, it was installed in the feeder and everything worked perfectly. I guess that timer was homesick and just wanted a free trip home for a visit.
In reality, it may just have been slightly corroded contacts, and removing/reinstalling it made contact.
To overwinter the feeder, some clients have them pretty permanently mounted. I've had good success by cleaning the feeder out, turning it to "off" for all feeding cycles, and leaving the battery hooked up to the solar charger. Next Spring, fill with food, program feeding schedule, test and walk away.
