Ignition trouble
I think I got the loose wire back in place.... now
when I go to turn it over it attempts to turn but
only manages a single click follewed closely by
a "wire noise" that comes from the dash, it will
only do this the first time I try to turn it
over, other than that it doesn't do nothing,and
i have to wait a day until it will do the click agian.
Is there something in the system other than wires
that can cause this?I cant see anything wrong with the
wires,their connected etc. the truck is a 1970 camper special
w/390 4speed manual everything.
help as always is greatly apprecciated

check your battery cables, take them off and clean them real good.sounds like a loose or corroded cable. also check your ground cable at the block. make sure it is clean and tight. sometimes they will rust between the block, bracket, or what ever it is bolted to.

Try the screwdriver trick. On the solinoid, short from the battery terminal to the S terminal. If this cranks it over ok, the ignition switch or the wire to the S terminal has a problem. 
The wire noise does not sound good.

I got a wire to my alternator but there is no block ground
wire... funny how that is my other 390 has wires to side
of the block but it's from the fairlane, 69 i think,,
What is a ballast resistor? cause I think the noise
comes from an area described as having a ballast resistor,the \
stereo area of the dash. what about solenoids? whatever
went wrong did it within 4 seconds between cranking and
an attempt to crank after i pumped some gas into the pig,
its something that rattled out of place,

The ballast resistor is a piece of wire that is made to have a certain amount of resistence to it. Regular wire does have resistence but it is very low. The purpose of the resistence wire is to drop the voltage going to the ignition coil to around 6 or 7 volts. The coil is not made for a constant 12 volts. During starting, the resistence wire is by-passed by the I terminal of the solinoid to allow easier starting.

You are totally correct in your description of resistance wire. However a ballast resistor is a separate component. Some trucks have the resistance wire others have normal wire with a ballast resistor in series with the wire. The ballast resistor does the same job as the resistance wire.
