[GreenKeys] 2 1/2A SCREW IN FUSE

Sat Aug 12 16:39:25 EDT 2017

The easy no-solder fuse adapter requires one of those two-prong outlet
adapters, of the type which screw in to a standard lamp socket. I'm sure we
all have a few of these lying around, they were very common in the older
days.

Then you need an inline style fuseholder with wire pigtails and a 'quickie'
replacement electrical plug. Stick the wires from the fuseholder into the
replacement plug as if they were a lamp cord and then lock / snap the plug
mechanism together.

Put a 2-1/2A fuse in the holder, screw the adapter into the TTY fuse
socket, and plug-in the fuse assy. All done, no soldering - though I
suppose you could use a solder-type replacement plug, rather than the
quickie mechanical type. For additional safety, you can pull out the fuse
assy any time to provide a solid visual verification that the the AC line
is open and the unit cannot start.
