Ground Stud Nut over torqued
2 weeks ago ( Feb. 12, 2017 ) my right headlight started
failing. So I ordered 2 HID D3S bulbs on Amazon and scheduled to tackle
that job this weekend. Then last Wednesday I got "Coolant low" message.
Made appointment with Tesla service but was assured not to worry -
probably a bad ground. The I got intermittent 3 beeps with a message
flashing on the IP and main screen but not long enough to read. Also
"Suspension needs service popped up frequently. I got worse yesterday
while driving in the morning. In summary the following happened
Drilled into the broken stud and tapped a thread
Then sandpapered the stud and brass lug connected to the 2 wires. Temporarily connected a jumper cable to the brass lug and low and behold the headlight worked and all warning messages disappeared.
Went to Hindle's Hardware in Clarksburg Ontario ( that
is in the area where I was visiting ) and got a brass bolt with 2 nuts
and special electrical paste for joining dissimilar metals. Reason for
brass bolt is that the lug on the 2 wires was already brass.
