First check you have 12V on the 14pin connector, between 12V IGN & Ground.
11.78 is close enough.
I'd find a pc with a proper serial connector, to rule out the usb to serial adaptor as they all have different chipsets and some hardware don't like certain ones etc.
11.78 is close enough.
I would be checking the voltage at the battery, if it is fully charged and giving 12.8 volts then 11.78 is not good at the socket, it points to a bad connection, dont forget that your volt meter is putting no load on so a bad connection can give a low reading which breaks down completely under load, try reading the voltage with your gubbins connected, Rick
I will see if mines lights up without the serial adaptor connected etc.
Can't remember if it needs to be connected too?
