Hope someone can help. I have a 1992 Defender 110 CSW and have recently had issues with it failing to turn over (ignition switch to start and nothing happens) when ambient temps are cool (sitting in the shade and air temp is 23C or cooler). As soon as sun shines on it and warms up, turns over like a champ. I have replaced starter/solenoid, starter relay, battery, ignition switch and I am now thoroughly confused. Any suggestions?

Have you checked all the Earth's?

All components have good grounds based on readings with a Fluke.

You cannot have to many earth on the 200, I put extras on mine and it made a difference, the main on you want is direct from battery to the flywheel housing studs near the starter, one thing to check again is the starter motor as even the new ones are not much cop.
Well worth going over all the heavy connectors again as mate had similiar problem and we traced it to a loose nut on the starter motor solenoid.
Worst thing with the defender 200 is starter motor access.
I may be wrong but I dont think the 200 had a starter relay? hence the rather heavy wire from ign switch down to the starter solenoid, white with red tracer iirc.

Thanks, lynall. I will check the earth locations again. This really has me baffled as I was having no problems until late Jan/early Feb and the sensitivity to the cooler temps has progressively gotten worse. Cheers, Ox

I reckon its a coincidence, I had a few issues with mine and in the end made up all new earth leads and a new starter and its been fine since,
The original earth path is poor, Ive had a couple of starters fail but only because they filled with mud, stripped and cleaned them up, but the cheap britpart one is very poor quality inside.
