low coolant idiot light on but its full

I am putting the truck back together from removing the radiator and cleanning out, it had lots of debris in it. after putting back together and refilling with fluid the low coolant light is staying on. is there a reset somewhere or could the sending unit be bad.

if you dont have a sensor in the recovery tank the light should not be on so some points of interest could be: wiring harness near recent repair points, flexible printed circuit on instrument cluster (unrelated to repair) corrosion can occur there and cause bugus warning lights. has the recovery jug been replaced?

Bleeding the air out of the cooling system should solve this.

not on this one, it is just a plastic reservoir.

You do know that the sensor is in the plastic reservoir tank? If that's full and the light is on then try unplugging the sensor switch. If the light goes out then the sensor is bad.
