It appears that the accessory switch on the console of the 1999 Ranger Cherokee 207 I just purchased is not working. All of the accessories work regardless of the master accessory switch position. On my other boat the accessory switch turned off all other switches. Does this one work differently? If it is not working properly, how would I repair it? Thanks, I didn't want to take it apart until I knew what I should expect. I assume the switch is important to avoid unexpected battery drain if another switch is on.
