I installed some blue led lights on my boat. The bilge pump and Nav lights were working correctly prior to the installation of the leds. I hooked the leds up to a battery each step of the install to ensure they were working. When I hooked the led's to the wires running from the white running light to the toggle, all of a sudden nothing worked. I took the led's off the circuit and just hooked up the running light and then none of the running lights worked when I flipped the toggle. I checked today and noticed that the bilge is not working either. I pulled it prior to installing the led's and rewired it and it was working great. The other thing that I find and can't understand is the horn is not working. I replaced the toggle switch to the aux, live well and the Nav lights. Just can't seem to locate what the problem is or where to begin. Any assistance would be greatly appreciated. The boat is a 1994 Neptune Sunbird and runs fine with no problems. Thanks again for any help you may have. I'll check back and see if there are any questions..
