My flasher wire burned up!

I recently installed a new alternator and voltage regulator and new flashers for turn signals and 4-ways. My battery was low when replaced them from the old alt not working and I went out on a drive without charging it (Duh) . At a gas station it wouldn't start, so I got it jumped and came back home. I noticed I kept hearing the flasher relay clicking occasionally on the way home although the lights were not coming on and when I got in my driveway smoke poured out from under the dash.
I shut off the engine and the smoke stopped, and I found what burned up. A while ago I had replaced the steering column wiring and it came with an adaptor for going from the curved plug of the old wiring to the flat plug of the new harness, and a wire on that adaptor was melted. The burned wire was connected to the purple wire that went to the turn signal flasher. I also noticed the flasher seemed very hot. (I don't know why a fuse didn't blow first before the meltdown). Could this have been from driving with an almost-dead battery? Any way to prevent a future meltdown (Or roadside fire?)

Re: My flasher wire burned up!

Sounds like you had a high resistance connection or two. You can have melted wires and connections without blowing a fuse, because the connection was poor, producing heat. Best way to avoid this problem is solder and heat shrink all ring and butt connections, on plugs make sure they fit tight, if they don't bend the metal tabs with needle nose pliers till they do.

Re: My flasher wire burned up!

Could the wiring to my flasher have burned because of the type of flasher? The one I bought was a heavy duty one and is electric, not thermal. The original thermal one was also heavy duty. I still don't know why the flasher was clicking when it wasn't being used.

Re: My flasher wire burned up!

I found the problem just today. I leaned on the steering column to pull out the flasher to look at it, and the lights started going nuts again...I found that the steering column wiring was being pinched by the bracket that holds the column up under the dash. I taped the bare spot in the wires up and ground the sharp edge down on the bracket and now it is working normally again.
