See General Note #3 above: No voltage at the BATTERY VOLTAGE SENSE terminals tells
the controller that the battery voltage is low and needs to be charged more. Install a
connection from battery to "BATTERY VOLTAGE SENSE" terminals to resolve..
See General Note #8 above: A damaged temperature sensor or wire will cause the controller
to malfunction and requires immediate replacement.
CONTROLLER NOT IN CHARGE MODE ("CHARGE MODE" LIGHT OFF)
Disconnect solar panel, then reconnect. Listen for relay to click and for “CHARGE MODE"
light to come back on. If the light goes on but you hear no click, the relay or controller may
be defective.
Check for other charging sources that are not properly regulated, causing the battery to
overcharge.
