Pro-Trak chargers

[Frio]

Hello everyone,

Does anybody remember the Pro-Trak battery chargers?

I still have two of them (found them after many years in the basement), but they don't seem to be working when connected to a power supply.
I vaguely recall them both shorting out at an indoor race...

The support website is seemingly non-existent anymore, so does anyone know if they can get repaired anywhere?

Cheers,

Frio
