I recently purchased a 2001 Marlin. ..I can't find a model or manufacturer for the onboard charger. Seems to be working, but I would like to know who makes it. It may or may not be the original, Here is the description: Grey color, about 14"x7", 2 red led's and 2 green led's, 110vac is hardwired at the bottom behind an access door held in place with 3 screws. Does this sounds familiar to anyone ?
