I have a 2006 Sun Chaser pontoon, my question is if I turn the key on to use my accessories does it harm anything in the ignition system? I don't have an accessory on the key switch just the on then the far right to crank the engine over. I remember the older cars ( going back a few years ) it would burn out the points or condenser, want to use my depth finder but it is wired into one of the switches that require the key to be on. Thanks
