First Failure
I tried to open the dynamo to clean it but failed, as the pulley just wont come out. SO went ahead & dipped in thinner & did some brushing. A lot of muck came out of it but when I tried to tighten all the bolts I got to know that there is something wrong & that pulley is not rotating freely.
Here is the procedure to destroy a alternator
I took the alternator to the auto electricals shop & later to the lathe - sorry cant open it. I took it to my known friend on J.C.Road who told me the exact problem with the alternator, my thinner idea has literally melted some parts within the alternator & 90% chances are there that the rectifier wont work now. Replacing rectifier will cost more than 1K, pulley swap just not possible without opening the whole alternator.
Some news about alternators:
1. Always skip MICO/Bosch dynamos for such mod purposes, as their design is such that the pulley cant be swapped to a different type one without expensive labour (not all but the one that I have is always troublesome)
2. Maximum parts sharing happens between TVS alternators, so its very easy to swap pulleys etc
3. Easiest to fix, cheapest to buy as used one is the Denso (least troublesome as per the electrcians words)
This is a major set back as I had just managed to get the mounting etc properly bent & filed to fix the new alternator. Also dumped my old cheap speakers as an exchange for the alternator socket (Yes! I got that too). Now since the dynamo has gone kaput, I am planning to get back to the regular one/ a refurbished Zen (denso make) dynamo.
So there goes my 2K to the bin
