locate controller... check fuses.. connectors.
with light going ON then slowly off.... might say.. 2 fuses.. master and slave fuses.
or bad connection someplace.
best of luck. a 12 volt trouble light will be handy with this one. auto parts store.
a cheap one will work. but NOT an LED type..
older type with light bulb.. for a LOAD on the circuit.
