There's no such thing as an alternator 'cut-out' or relay. The whole charging circuit is protected only by heavy duty fuses.

There is also an "Alt-S" fuse under the bonnet. Please check that too. The 'S' stands for 'sense". If this fuse has blown the alternator rotor field coils won't receive the excitation voltage when you turn on the ignition nor will it be able to 'sense' the battery voltage. Hence the name.

Have parked it in closed garage. Will send it to asc when time permits.
I'd recommend you disconnect the battery -ve (negative) cable if you intend parking the car over 10 days.

Whole thing was my mistake, firstly not trust a roadside mechanic to jumpstart ( which created the whole problem). Don't trust a new driver who we often felt pilferaged fuel. Hadbadi mein bahut gadbadi ho gaya
Road side mechanics follow the 'jugaad' system which means they just want to get the job done and the vehicle running. Safety does not figure in their calculations. The owners manual has clear instructions on how to jump start the vehicle. As an owner you should take the effort to become familiar with the process.

Yes boss.
As I said I was in a hurry on Sunday to go somewhere with a large group in 3 cars. In a hurry to get the job done quickly we overlooked what the mechanic was doing. Few seconds of negligence on my part and the damage was done.
It was a Sunday so I couldn't attend the car and left it on the driver. Again negligence on my part.
I didn't even check or start the car until today. Again negligence
It had been raining non stop since Sunday and I was busy too- again an excuse on my part only.

A new battery amazon was added on Monday. I am sending it to asc through old driver who has maintained it the car since new. Should go in a day or two. I hope I will just have a to pay the money and everything will be alright.
Moral: if you don't have time, just park it aside and wait till you attend properly- use other car if you have else public transport. Shortcuts will make a simple push start and a new home delivered battery issue into many thousands and week.
This was the first time in 6 years car car went outside asc.

The best (and reliable) thing to do is purchase the heavy duty copper cables of the required length (like Finolex rated for 600 Amp) and buy the jumpers clips and join them to make the jumper cables. The longer the cable, the thicker the copper wire needed.
What I had done ages ago was
. Bought a long length of starter cable for Fiat 1100
. Searched for and bought large copper clamps from Junk shop
. Got the clamps soldered by Radiator repair guy

You can do the same, the only problem is finding heavy duty clamps. Most available are quite thin. Here a few that are sturdy

A few shops in JC Road, Bangalore are selling jumper cables for 1250/ 1550. Stuff is very heavy with large clips. Manufactured by Delhi based company. The shopkeepers do not know the Ampere rating.

Not sure if they are significantly better than the stuff available on Amazon for 350- 500 bucks. Any suggestions, or personal experiences to share?
