Over the winter I put an 94’ LT1 into my 91’ firebird. Recently I started having problems with the ignition. I had wired everything else but the starter to the ignition. The starter I have hooked up to a push button switch. Due to my recent problems with the ignition, I ran 30amp switch to the fuel pump as well as a 30 amp switch in line with a 30 amp fuse to the PCM using 14 gauge wire. The fuel pump wire and switch I am having no trouble with, but the wire, fuse, and switch inline with the PCM is severely heating up to the point that it is melting the plastic surrounding the wire. The fuse has not blown yet, but the wire is burning hot. Any advise is appreciated.

Thanks

 

from my experience (not a whole lot but enough) when the wire got hot, either something was shorting or the wire was simply too small.. higher guage wire might do the trick and check for any loose wiring that might be causing a short.. also, before you start hacking at your wires, get more input from others on the situation first.. i may be wrong..

 

I forgot one more thing, the alternator is only charging at like 8 volts. Could this be another side effect of the faulty wiring of my switchs?

 

You are using wire that is too small for the application. I would have run 10 guage...maybe even 8 guage if you can easily do it. You are lucky that this hasn't caused a fire yet...

Also, check your grounds and make sure that you have a solid alt charging wire.

 

14-AWG is good for 15 amps, 12-AWG is good for 20 and 10 AWG is good for 30, nothing wrong with going bigger though.
