The question I have is that I have a bank of 4 toggle switches on the upper left hand side of the dash. reading right to left symbols on switches are as follows: Music Note, Picture of Fan, Trumpit, and last is a battery. I understand the first three items but the battery switch I can't figure it out. When I push it down nothing happens, I do here a click somewhere under the dash. Do you have any idea what this switch is for?
Just below this 4 toggle switches is another bank of 3 toggle switches. Reading right to left, Lighting bolt, Looks like a headlight, and third switch has a pair of headlights. First switch is for the generator but don't know what the two with lights are for. I have a light switch and windshield wiper switch below these toggle switchs and all seem to be factory install. Any ideas will be greatly appreciated.
