DSE fuel injection adjustment

OK, hard to believe...
Sometimes things just take a positive turn, even with a RR!
My starter motor, a rebuilt unit replaced three weeks ago, failed. Took it out and back to the place I got it from and got another. Meanwhile, I thought, lets take a look at the flywheel sitting exposed with the starter motor out. I could now easily make out the engine rotation direction by the marks on the flywheel teeth. It turned out that zzr1200 (the names people here have...) is right! I was rotating the motor the wrong way. 'Clockwise' in RAVE is looking BACKWARDS facing the motor! Not the most natural designation. And, my flywheel looks nothing like the DMF you see on youtube, or in RAVE. It has large holes on its face and just one timing hole.
So, I repeated the RAVE procedure and now things made much more sense. After several tries, making sure the final pump movement is towards the engine, I got the 0.90 mm exactly to specs. Reconnected the fuel lines and manifold and within minutes the engine was running great. And, my MSV showed 52% timing modulation, well within the 'specs'. What a feeling. My second DSE and 4th injection pump and its the first time I see the modulation below 85%...
Well, it would have been a happy ending but, true to the RR tradition, my charging light is now constantly on...
Thanks everyone for your help!

Well done that man. You have learned something from this for the future. Charging lamp on a P38 is not switched by voltage balance as others are, it is switched when a voltage balance is detected by the Becm then switched by that. Data is your man for that problem i think

Thanks Wammers! Yes thats right, the alternator charging is detected by the BECM which then operates the charge lamp. First stop, check the alternator is charging, 13.8 to 14.5 volts at the battery with the engine running. If the alternator is charging then you are into corroded connections, bad earths etc:(
 
It turned out that I was so focused on the FIP adjustment I neglected to properly connect the charging cable from the alternator to its prong on the starter motor. My fault entirely, nothing to do with the Range being a Range.
Next, the turbo. After I get back from two months in Stanford, CA!

Yup, putting everything back on, that you took off, is a good idea.:)
