Default So, I may have fried a haltech...

A friend has the Haltech Sport 2000 and accidentally broke his USB plug and Haltech said that the repair would be $140...

So we decided to cannibalize a USB plug from a printer that was being thrown out and we swapped it over to the Haltech. In the process I slipped and put a "scar" on the board with the soldering iron... It doesn't break through the gel coat but it did touch one of the traces. Also, I noticed a point between pins 1 and 4 had what looked like a bit of copper exposed and I was worried that perhaps it was shorting.

Anyhow, before we noticed all that we tried to connect it up to the guys laptop and you could hear the sound of windows detecting a USB device. However, the Haltech software kept saying "ECU not found." It was time to leave so we pushed the car out and I headed on home. I got a text from him saying that the blue light on the ECU doesn't even come on anymore...


How likely is it that I fried his ECU?

I did some research that there is a polyfuse on the ecu board itself and perhaps that is what happened. I am just surprised that windows would see the USB chip and still fry something?

I am REALLY REALLY hoping I don't owe him an ECU. I already offered to build him a megasquirt to get him on the road.
