I bought a Prolong Battery Discharger on ebay and I have tried to use several times, but it does not seem to work. I opened up the case to see if it had an internal fuse that might be blown. I did not find an internal fuse and I did not spot any obvious problem that suggested anything has burned out, but the unit does have a loose wire. I have attached pictures. Does anyone know where this wire is supposed to connect? I can't believe that this wire with a loop style connector is supposed to just be loose within the case.

Is anyone familiar with this unit? Or have one and want to take a couple minutes to open the lid and see where should be connected.

I think maybe it is supposed to just be connected to one of the mounts to the pcb on the lower surface of unit.

I have sent photos to the Hybrid Automotive folks but they were only interested in having me ship the unit to them for possible repair, they did not seem interested in just telling me where that wire should be connected.

Thanks

Mike

 

You don't see a fuse?



With a PCB label like "TH1", and it's position, I suspect that's an internal temperature sensor.

 

Not my best moment. Thanks for the help. I was expecting to find an inline fuse like the one that Prolong uses inside their charger. I checked this fuse, guess what? It's blown. Ok, going to try a new fuse and leaving that wire loose and see what happens.

Thank you, Steve

 

We all have days like that. Hopefully that does it.
