There are many ground points that need to be checked. Also if any aftermarket electronics have been installed the wiring system could be compromised. Easiest way to find a short is to use a 'Short Detector'. Other wise is to go through the schematic and check every wire in the circuit. 2nd gen seven is notorious for electrical issues. Especially if any of the system has been tampered with.
