if the battery is almost dead, then trying to start the motor will cause
the rest of the electronics to experience a significant power drop.
This may explain the "IL loop broken"
Try to send the drive a command that does not require a disk access
(e.g. the ID command that returns the type of the device).
If this works then chances are that the 9114 electronics are OK,
however, it doesn't tell you anything about the diskette drive itself.
To test this you need a fresh battery, as Tony Duell mentioned, an
unregulated power supply will do, but you need to make sure that it
can deliver around 2 Amps. I have succesfully run an 9114 off a
bench power supply so the procedure works. Just make absolutely certain
thatn the polarity is correct (since you are feeding DC to the drive).
If you can open the case, things will be easier for you as there is lots
of space inside the case so the wires and connections are easy to reach.
If you can get a floppy cleaning diskette, you should clean the drive
heads before testing.
Once you determine that the drive works you can get a replacement
battery for the battery pack and you are back in business.

I have used the same PowerSonic part for my 9114 and it fits like a glove.
To get inside the battery pack, you just remove the two screws and carefully
lift the top cover after you lift the various latches situated around the top
cover. Apart from the TORX screwdriver, you don't need any other tools to
replace the battery inside the pack.
