It could be the shore power/plug or other boats causing it all.
Can you get a volt meter on a plug, check volts, then turn the charger on and see what the running volts are? Avg. will be 90-110, a low of 85 or lower volts wont really cut it and is usually caused by other boats w/ high current draw.
