Mine used to do exactly the same. I cleaned all connectors with no real improvement. I found that one of the previous owners had removed an alarm and simply twisted the wires back together rather than crimp/solder. This joint was badly corroded from arcing etc. Bewildered and was fine after. I found it by using a multimeter on the batt and one of the connectors under the tank.
