First of all, I am sorry for some mistake on my side due to which I gave you incorrect feedback.But now I give up - I have no idea why the diode is overheating.
The bikes, I am working on have single phase stator.Are you missing a wire? Most motos have three phase stator so you'll need 6 diodes and should have three wires from stator.

I have been testing my circuit mostly on Bike A (sometimes on Bike B and C). All these three bikes were equipped with original stator (generator) which has a pair of coils, both having one end grounded to the chassis. That’s why as per your evaluation the D3 was getting hot.
When I received your instruction for checking the stator coil I was away from my work place and I checked another bike D (similar model). Unfortunately, it was equipped with Chinese stator having single coil which deceived me to forward you incorrect information.
When you gave up, next day I tested the circuit on bike D and found it to be working perfectly. That confused me so I checked the stators of bike A, B & C and then got the whole picture. Luckily, I found the manual of the bike on the net which confirmed that, that model is originally equipped with dual coils having one end grounded. Therefore, my circuit is not suitable for these bikes. Hence, my problem seems to be solved. However, I need some modification in my circuit to suit these bikes and I hope to start a new thread after some initial working.
Really grateful to you and all others for sparing time to help me.
