Just get one of those USB charger that plug into the ciggy plug. Those that comes with the Voltage reading is good. You can see the voltage fluctuation in real time easily. No need to guess or use volt meter.

Alternator inside has some carbon brush and ball bearings

If your battery can't charge properly then alternator might on its way.

My old kenari alternator kacau around 190,000km.

I think yours still have plenty of life in it

After My Iswara has done 250,00 km baru I suspected the Alternator got issue now.
I think you dont need to do anything to your alternator. It should be able to last more than 200,000km before you start to worry.

Hi guys,

My 08 Myvi is having some problems with the electrics. Just changed to a new battery and started like normal but once turned on the head lights, the engine dies. Tried a few more times and the same problem happened.

I suspect that this is the fault of the alternator but I need some clarification before spending a large sum of money on repairing the car. Money is very tight at the moment.

Went there las week. On avanza 2006 wit 2xxk km mileage. Thumbs up. Jus minor service plus change carbon brush. Rm100. Go behind sshop as front shop getting hot.

how many hours it took to repair your alternator?
