§1What this business is
An alternator turns engine rotation into electric power for a vehicle's lights, wipers, indicators and fan, and charges the battery that cranks the engine. The unit assembles alternators from bought parts, tests them on performance, speed and endurance rigs, and sells to the replacement market and workshops.
Capacity: 6,000 alternators a year.
§2Is it right for you?
Who it is for
An auto-electrician or electrical engineer who knows the spare-parts trade.
Who it is not for
Someone without access to working capital or auto-parts buyers.
Advantages
- Every vehicle needs an alternator; the replacement market is large
- Low machinery cost — mostly tools and test rigs
- Good turnover per worker
- Testing capability builds trust with workshops
Drawbacks
- Working capital is over 80% of the project cost
- Margins are thin — raw material is about 82% of sales
- Must compete with branded OEM and imported parts
- Quality failures on the road hurt reputation fast
Skills you need
- Auto-electrical assembly
- Testing on rigs (meggar, high-voltage, temperature-rise)
- Parts buying
- Selling to spare-parts dealers
Why difficulty 3/5: Tools are cheap, but working capital and quality testing decide success.
§3Market
Who buys
- Auto spare-parts dealers
- Vehicle repair workshops
- Fleet owners
How it sells
- Spare-parts wholesalers and retailers

How the investment is worked out: Equipment ₹3,00,000 (tools, test rigs, dies, office equipment and pre-operative expenses) + working capital ₹14,45,000 = ₹17,45,000. Land own; no workshed cost.
Working capital: Working capital ₹14,45,000 — most of the project — because raw material runs ₹78 L a year; the profile works out ₹14,44,975 per cycle.
