trop-a-cal, the battery is three and a half years old and has been run down twice (both times while at a dealer). But it is a marine battery so that shouldn't do the damage it would a car battery. Still, it's shown signs of weakness lately. I'll change it out as a first move.
Cleaning the carbon seems like something that should be done anyway. Thanks for letting me know
Even a marine battery can be damaged by running it down if it is left in that condition very long. You should invest (and learn to use) in a digital multimeter so you can quickly determine if low voltage is an issue. To quickly eliminate the battery as a contributor you can plug your trailer in to an ad source and let the converter provide power.
