the alternator and starter parts have to be rummaged in the industrial salvage that are the little buildings inwards starting from the screws market. They have tons of bosch units that they break everyday for their material in weight. I bought a perfect BMW diesel starter which I made to work for my Golf Diesel - using the Golf's drive gear and front.. Cost me Rs2000/- My starter's commutator and carbon brushes were worn - I rebuilt the whole thing to brand new performance.
The alternator pieces have to be cross checked with a sample in hand - But be prepared to move lots of heavy metal and get ALL of your clothes dirty for life (wear steeltoes for safety) - I sometimes had to climb upper levels to rummage fans, motors, alternators and starters (being 300 pounds and 6'5" doesnt help in a small place)
If you guys want to buy a genuine type - Grounding cable (braided type thick piece) You can find it there too.
About Rs100/piece - its legit as they are going to hack them up too - Ive seen shops/dakoos in Shersha ask for Rs 2000/- for a regular 14V Bosch regulator - My reaction was - Are we supposed to laugh or smoke the same stuff you are..
btw ZNaqvi - I believe we share the same name.
