no card produces a failure the original problem was, likely, a card which was
not properly inserted.
Bad Power Cord
Unplug and replug the power cord at the point where it connects to the IIe.
Turn ON power. Try wiggling the power cord. If the Power Supply comes ON at any
time, try substituting a power cord from a known-working IIe. If this fixes the
problem, you can be pretty sure that the problem was a power cord with a broken
wire.
Poor Power Supply Connector Connection
Unplug and re-plug the Power Supply cable to the motherboard. Turn ON
power. If the machine seems to respond, or responds when the connector is
wiggled, you probably have a dirty or loose connection.
Clean the power supply plug and socket with an alcohol swab. Using long-
nosed pliers slightly re-crimp the 'holes' on the socket (or, insert a jeweler's
screwdriver into the space between each hole and the plastic casing and twist).
The idea is to restore a firm grip for all contacts.
Another possibility is a loose or broken socket solder connection to the
motherboard. The repair is to remove the motherboard and re-solder the
connections to the socket.
Bad Switch
It is fairly easy to identify a bad switch-- it will, usually, not snap
cleanly into position, feel crunchy, and/or have a burn spot. The repair is to
replace the switch with some AC power switch that will fit. Or, you can
permanently connect the switched lines and add an in-line switch to the power
cord.
Blown Fuse
Some power supplies may have a fuse. Open the power supply. Look for a fuse
mounted to the circuit board. If there is one, check it. An Ohm meter can be
used to check for continuity if it is not obvious that the fuse is blown. If the
fuse is blown, replace it.
Bad "Globar" Element
Look toward the end where the power cord is connected. Somewhere close to
the place where wires from the switch go to the circuit board there should be a
small disk-shaped component which is not a disk capacitor. Probably, it will be
black with no markings. This is a "globar" resistor. Check it to be sure that it
is not cracked and that both leads are really connected to the disk.
If the globar element is broken or if a lead has popped off, you will need
to get a replacement from an electronics supply shop. (Tell the shop person
where the globar resistor comes from and describe its size.)
