Can't Find Ground

I have a 1987 Carrera. I have done a lot of research on this forum in trying to locate my ground points throughout the car. Several of the forum members spoke to a ground point behind the battery. For instance one member wrote: My 87 has 1 ground coming from neg. side of battery to the front fender. Pull the battery and its right there. Ground from battery might be 8 inches long. When I checked the ground, ohms, on injector connection, my meter was around 14k ohms."

I have pulled my battery and there is no ground point or wire. I have checked for this over and over. Can someone please direct me as I need to find all ground points to deal with a no-start issue

Also, does anyone have a picture of the various ground points. I have the diagram that shows the ground points it is simply an illustration and not a photo of the different grounds. I am not mechanically inclined and so I really need to be able to see what the ground points actually look like so I can check them

Thanks so much

Follow the negative (-) battery cable. What is it connected to?

My 87 has a ground to the inner fender, not the fender itself. If you can't locate where it terminates, it must have been modified AFAIK??

Follow the above suggestion or post a picture of your battery. Could you crank the starter?

Follow the ground cable, see last 2 pictures. Look under the mess of cables and windshield washers hoses.

Since we are on the subject of grounds, anyone know what/where points #13 (XIII) and #14 (XIV) are? Are they part of the taillights? I ask because I have an intermittent turnsignal indicator "weirdness".

Weirdness = Several times now, at night, with the lights on, my turnsignal indicators have been sort of illuminated all the time. They still flashed when I used the turnsignals (not sure of the turn signal lights them selves though). Last time, I drove 3 miles with this problem, stopped for gas, when I started the car again problem gone. My first step to try and address this problem is check all the ground points and fuse/fuse contact points. Car is a stock 1976 911S.

Thanks
