PUMPKIN CAR STEREO SUPPORT CENTER

I've had this installed in my truck for about 3 months, but haven't used it much. I blew a fuse in my truck and tried to replace it, but it kept blowing. I traced it back to the head unit which also had a blown fuse. I replaced that, and it blew again. I unhooked everything and checked all the wires and it seems that the 12v+ wire of the pumpkin is grounded internally. Also, I bought it used, is there still any sort of warranty?

Hi,
Thanks for your information.
After discussing your issue with our technician, please check if the wires are short circuit ,such as the yellow battery wire with black ground wire, and the red ACC wire with the black ground wire.
Please attach the picture of your original wiring harness, we will help you check and try to provide you positive solution.
Your unit is still under warranty, and you can choose to return it back to us for repair.

Hopefully the pic is good enough. I'm showing continuity between the ground and the yellow 12v wire of the pumpkin unit. It was in the truck working fine for a few months before this happened. I've replaced with another unit that works perfectly fine, so I know it's not the truck.

Hi,
With respect of your description, the unit maybe broken inside.
You can contact our customer service to return it back for repair.
Regards
