Hi Nodge, engine was running when fluid level checked. I checked that before (with the pump) and pumping fluid all good. I did it a slightly different way but same idea, I d/c one of the unions and put it in to a plastic bottle... clever hey?! No mess..! And fluid is pumping all right. Hi Hippo, I d/c that yellow connector both at the driver's side then the other at the passenger's side after removing the battery and used a multimeter on resistance and spun the wheels manually before I got that result. However I must concede, it wasn't single wheel spin as I trolley jacked the front of the KV6 thus both front wheels in the air and were turning. Come the weekend, I will do that test with one wheel up only, or as you stated, I can lift the wheels very slightly off the ground and use wheel chocks on the passenger's side front wheel. The VCU and prop and IRD output shaft are all removed so no need to worry about the rear wheels. I will put it in to neutral and try that test. Btw, I rang some landrover experts around here including one dealer who put me on to this mechanic not LR but independent but claims to know FL1s very well... he stated that my no drive could be affected by the propshaft and IRD output shaft having been removed - it's a complicated explanation so I will quote verbatim, to me it doesn't make sense, but he stated that "the system on the KV6 suffers from a lack of balance when you remove the propshaft and the IRD output shaft and fit the blanking plug and some safety feature has kicked in and locked the torque converter thus disabling all drive". He thinks I should reinstate the entire propshaft and see what occurs. It doesn't make sense to me as there's a lot of other people such as Hippo that run their KV6es successfully in 2WD mode. Even if there is a "lack of balance" due to the absence of the propshaft for the KV6, how would the KV6 control system be able to tell, does it have eyes behind the rear exhaust manifold?! (lol).. Nuff said, I'll be trying that one wheel test next weekend. I haven't changed the brake light switch. Any other way to test if the brake light switch is the culprit before changing it?
