My alternator stopped working couple of months back and the local workshop guy changed the same with a used alternator claiming that the replaced one is of 5speed 800's only.
I had to drive in a night last week when it was raining heaviliy, for half an hour. my headlamps, A/C, wipers in full speed and music system was working. After half an hour, all these gradually stopped working but somehow I reached home. I could see that my battery was fully drained.
It was a clear indication that the alternator couldnt generate the power as required. Now my plan is to buy a new alternator. Arun - Could you please suggest me on this? Can I buy an Alto's alternator? How much it costs? Good suggestions are welcome please.
Welcome to TAI
Regarding your alternator issue just do a quick checkup yourself. (arrange for a multimeter if you can, to measure the battery voltage)
Step 1: Check the alternator belt for proper tightness. If you press the belt with your thumb it should press only to 1/2 inch.
Step 2: Check for any cracks in the alternator belt
Step 3: Sit inside the car and turn the key to ON position. The battery light(in the meter) should glow. If yes
then the wiring is ok. If no
then the bulb is fused or the wiring has some problem.
If the bulb is fused or some wiring is missing then the alternator will not be able to charge the battery.
Step 4: If the battery light glows in ON position, then start the car and see the light Does it go off ?? If yes
then the alty is ok. If no
then rev. the engine to higher RPM and see if the light goes. NOTE:
for step4 the battery should read at least 12v in a multimeter.
If the alternator fails in the test, Just take your car to a local mechanic(car electrician) and get the alternator checked. BTW: How much did you pay for the used alternator ??
. If he is able to resolve your problem for within Rs. 500/- (by replacing the brushes or repairing the rectifier plate or checking some wiring in your car) then its ok. Else you should go for an alternator upgrade.
Maruti 800 4spd alternator is 35amps and costs Rs 4300/-
Maruti 800 5spd alternator is 50amps and is out of production
You can install Santro's alternator. Its 75amps and costs 4800/-
The prices are dealer's price for LUCAS-TVS in Lucknow(UP) and may be different at other states.
