Earth Connection

[Aerodeck]

Hi All

I installed a "no holes" reversing sensor in my Avensis rear bumper but it beeps randomly. I read somewhere else that it's probably they earth connection and when I test the voltage between the earth bolt and the reversing light, it's about 9.8 volts. The actual Battery read 11.94V.

Therefore, any idea how to find a good earth around the light cluster ? I tried the three visible bolts with the same result. Maybe the lights actually only work at 9 volts ? What earth do the lights use, I can't find one.

Any tips appreciated ! Cheers :)

Any available nut/bolt (on the inside of the car) that goes through the body panels will do. You will need to scrape off/sand off the paint around the area that the eye terminal contacts against. When done, spray over the area with spray grease/waxoyl or just spread some loose grease over it to prevent corrosion.
