The Alternator Pulley Tool is only needed if you are replacing the pulley. If you are getting a rebuilt Alternator it will come with the pulley installed and you won't need to remove and replace it.
However the roll pins should be transferred from the old Alternator then pushed flush into the rebuilt Alternator and then when everything is aligned pushed into the engine block. If you don't do it this way then is is extremely hard to et the Alternator to line up (ask me how I know?)
Go to 8:50 in the Video to see what needs to be done.
You will need something to push the dowel pins into the block.
Thank you once again. I did watch video about the roll pins, made a tool out 9f a bolt just guy did in one of the videos I watched.
Reading further into one of the forum subjects I ran across where the discussion was about the little blue wire on the alternator. I disconnected it and the battery warning indicator still came on and stayed on. I haven't had time to track it through the wire loom yet but I'm on that asap. Haven't ordered an alternator yet. Is it possible that little wire is stopping the alternator from putting out anything because it's not receiving proper or no input from the ECU?
The ECU controls the Alternator and it uses the BLUE wire to do this
This chart shows that the Voltage output from the Alternator for a Wet Cell Battery will be be between 12.5 Volts and 14.3 Volts depending on the outside temperature
In fact at 120 F or higher temperatures the Alternator is not charging the Battery

This is the exact reason why I don't like all that electronic crap in these vehicles and the new vehicles being put out. I miss my '77 GMC Sierra Grande 15!!!. Only so many components and when something went wrong you knew exactly what it was and it was usually pretty easy to fix.
Just with the alternator alone on this Rover there are so many variables that I'm second guessing myself on all the data I'm collecting because these other variables that I didn't account for. May be a good thing we haven't purchased an alternator yet as some of the data I collected was on days when the temperature was at record highs and and some after the vehicle had been driven adding to the overall temp. And just to think after all I've been doing it might boil down to this one little wire loosing connection
