Hi Gyani ji,
I wish to look into the 3rd point currently.
Just doing some basic searches threw up points which actually support Ambedkar's possible conversion along with the masses.
It must be noted that the climate at the time was one of deep hostility due to the strong possibility of Partitioning India, Which unfortunately due to the shortsightedness of the Indian Leadership (Ghandhi, Neru, Singh, Patel) became a reality. (My stance obviously)
"Dr Ambedkar and Untouchability Analysing and Fighting Caste" - Christophe Jafferlot
Pages 127 -131
"Ambedkar weighed up very carefully the possibility of converting to Sikhism... He therefore added a rider to his agreement; namely that untouchables converting to Sikhism would maintain their privledges gained by the Poona Act... He then won the approval of the Maharaja of Patiala, the most influencial Sikh Prince of India... Then in August 1936 [Ambedkar] agreed to lead a Sikh Conversion Movement and join Hindus and Sikhs in countering Muslim and Christian proselytising among untouchables."
"Ambedkar announced his choice of Sikhism in August 1936 because he preferred to have some responsibility for the future of the Hindu Culture and Civillisation"
"... In early 1937 negotiations between Ambedkar and Sikh leaders continued and meetings became less frequent and by the end of the Year, Ambedkar no longer mentioned the idea of conversion."
"...Among other factors accounting for his decision were first, that Sikh Dalits had told Ambedkar of the atrocities they had suffered at the Hand of the Jats... and second, the opposition to such mass conversions of the Sikh political class; The Akalis - Including Master Tara Singh-feared the leadership of the community would be wrestled from them..."

"Ambedkar converted to Buddhism in 1956, exactly 26 years after he had opted in favour of Sikhism"

There are footnotes in here which further support what is written, but this is only a preview book and i am pretty sure that this suffices for the moment.

Please note there is much more literature from other Authors (not Just Sirdar Kapur Singh) who all say the same thing.

I would suggest reading them all and then coming to the right conclusion.
Being perfectly honest, this is the first time i have heard anyone question such a fact which is clear as day and pretty much established by everyone.
I hope you do not mind me saying this, but i fail to see what is being achieved by questioning such things.
Anyhow, Gyani ji, would you agree with me in saying that the above shows that Ambedkar wanted to convert to Sikhi along with the masses but was stopped, stiffled and most probably disuaded by other parties who had a vested interest?
My best regards,
Lotus
