AquaPro ADF-75 Digital Replacement Timer - F2

A JAM message does not always mean there is a physical jam of the feed.  We have seen this error when the battery is too weak to run the motors through their cycle, or the motors are drawing too much amperage, like if the motor gets bound up or the motors are bogging down due to non ideal operating conditions (rust, dirt, etc).

If you are getting a JAM message...
1. Make sure the motors are not bound up, or there is clogged feed.  Clear out the feed and test the unit when empty.
2. If there is no physical jam, Take your battery and charge it with a wall charger. After charging, try the feeder again. (The charge meter on the timer only measures voltage, and does not test an amperage load.)
3. If you are still getting the JAM message, try unplugging the solar panel from the battery connection and test the feeder that way.  Sometimes malfunctioning solar panels can actually drain your battery instead of charge them.

4. Test your motors, unplug the timer from the white wire harness and connect your battery directly to the black and red wires, then test the blue and white wires.  Make sure each motor spins up when connected to the two respective wires.

If your motors run when testing them and the battery is fully charged, your timer might be on the fritz.  If the above solutions did not work, you might try contacting Aquapro support at 800-847-8269.
