I have a Gallagher S17 solar fence charger with, apparently, a bad output transformer, (a frequent problem with these models).
Checking the output terminals, I find that the coil is open. No hint of a voltage during discharge. There is the crack of the magnetic field collapsing, but it's much, much quieter than it used to be.
This transformer is proprietary, (part number googling turns up zilch), and costs $85 from Gallagher. Since the battery also needs to be replaced, unless I can find a cheaper substitute for the transformer I may as well pony up the extra for a new charger.
The discharge capacitor is 2.0μf 250V and seems to charge to about 200V before discharging. The maximum output voltage is stated at 10,000V, so I'm guessing the transformer turns ratio is 50:1.
The specs on the charger are as follows:
I hope an automotive coil is not my only option.

If anyone can point me to an appropriate transformer somewhere on the net I would greatly appreciate it. I have searched and drawn a blank there, as well.output voltage = 8.0kV to 10.0kV
pulse interval = 1.25 sec
Peak voltage @500 ohms = 2.21 kV
pulse energy @ 500 ohms = 0.11 J
current consumption @ 6V = 27 ma
