I have been blowing park light fuses at random for a year, sometimes will be o.k. for a month, sometimes a day. I have done Dave's parking light upgrade and my own headlight relay upgrade. Everything worked good after the upgrades, but now, two months later we are back to blowing the fuse. The good thing is now I have a hard short and can't hold the fuse at all. This is the wierd part: If I unplug The C-3 (black) firewall connector the fuse will hold. If I leave this one plugged in (C-3) and unplug the C-1 and C-5 (green both) lighting connectors it still blows the dang fuse..Any Ideas?
