Angry Burning ignition

I have just run into a problem with the electric system on my 68 Camaro.
I was driving today and stopped and turned of the ignition. After about 5 minutes I was back and when I turned on the ignition to start the engine there was nothing. I then noticed smoke coming from under the hood. The smoke was coming from the horn relay area. When I checked one of the red wires going to the relay it was hot and had melted the insulation. My first thought was that the horn relay shorted out, so I replaced the relay with no results. When I try to start the engine there was nothing and the red wire gets hot when trying to start (engage the starter) the engine. My cars voltmeter does not read any any voltage when I turn the ignition to the start position, however in the accessory mode I have full voltage. The engine in the car is a complete 350 GM turn key. The alternator has a internal regulator and as such does use an external regulator. I have had this engine in the car for over two years with no problems what so ever. The wiring diagram does not provide a clear picture of the red wire connections, where it comes from etc.
Any ideas??

Re: Burning ignition

Sounds like your starter solenoid is frozen in the "ON" position, or your starter is jammed, which caused a huge current draw.

Re: Burning ignition

I had a similair issue but the wire that was getting hot and just about caught fire was the right side wire. Too make a long story short, it was the high and low beam button that was damaged and was causing a short and needed to be replaced.

Re: Burning ignition

Check out your key switch. My key switch burned up and caught fire once. check for loose terminal or coming apart key switch internals. shorting or grounding out

Re: Burning ignition

X2 on the keyswitch, I replaced original switch cause the key would come out in any postion and the brand new AC Delco switch had a dead short when in the start position and caused my 16Ga fusible link to smoke on the dash power-up wire at the horn relay. replaced and all is good now, also learned the importance of fusible link in engine compartment.

Re: Burning ignition

Thanks everone for your input. As suggested by Jim in Mass [B]Sounds like your starter solenoid is frozen in the "ON" position or your starter is jammed, which caused a huge current draw." This was the problem. I pulled the starter and checked it out and on the bench it worked fine. I re-installed the starter and the car started with no problems and everything working properly. As Jim said the starter must have been jammed or the solinoid frozen. Thanks Jim
