Defender 200 TDI has had new alternator new starter motor new ignition switch. Did turn over but slow then all ignition lights went off and now dead. Any suggestions as to what to check. New battery on it. Please help.

 

Check your ground cable ends. Follow cable out of the battery box and clean connection to frame/body. My 1990 bolts to the frame/body behind the battery box.

Replaced everything, checked electrics/connections , turns over slowly though. Battery fully charged. What else can I look at. Please.

 

If the battery, alternator, ignition switch are all new and you've checked ground cable connections at frame/body...then my next guess would be poor positive cable or ground cable, rubbed partially through somewhere. Or the new starter is of poor quality or defective.

Have you tried jumping it with another vehicle?

Also, what was the condition of the engine, prior to this "slow turning over" issue. Not losing anti-freeze or anything? Engine ran okay? No knocking or such?
