We’ve initially replaced the starter. No change. Then replaced the starter again, with no change. Then changed all the battery cables with thicker new cables and a new ground cable from the engine to the body. Of course there’s a brand new battery. Still no change. Then tried an overlay from the ignition switch to the “s” spot on the solenoid to bypass everything in the middle like the NSS. We’ve lastly tried the Ford solenoid to bypass the solenoid on the starter trick and still no change. The entire starter diagram has been gone-through and still no change!
90% of the time the starter just clicks ones and lets off. Other times, fewer times, the starter will work I’ll drove off.
I’ve replaced the battery, cables, starter twice, glow plugs (which are fantastic now with starting), the ford solenoid, bypassed all the wiring from the ignition swith to the solenoid. I’ve jumped the solenoid and the starter engages perfectly. But using the ignition switch, it just clicks.
Recently noticed the reverse lights don’t work in reverse.
I am absolutely, completely, positively stumped. I buffet and polished the entire car and it’s so gorgeous but it can’t be trusted still! Do any experts have any advice? I can’t beleive I’ve replaced almost the entire system with no change

On the W123 turbo 300D there is a terminal block on the fender well so it is easy to jump from there and see if the symptoms are the same as when you use the Key. So it was easy to verify it was not the neutral safety switch or the ignition/starter circuit casein the issue.
When I had this symptom I bought new brushes and a new Bosch Starter solenoid. And when I got inside of the Starter the Brushes were severely worn out.
One of our Members said that if the brushes are worn out the Solenoid won't work right. To find out I replaced the Brushes and re-used the solenoid. That was around Oct 2019 and there has been zero issues with the reused Solenoid. So it was the brushes that were the issue.
