There should be a correlation on weak battery that causes the starter motor to fail earlier. However, until it’s proven, it’s just a theory. I believe the starter motor has aged and hence it started to deteriorate gradually. The weaken battery could have cause it to fail earlier but that’s just an assumption which no one could verify unless there’s a solid scientific research done on it.
Anyway, good to know it’s the starter instead of the ecu which would cost 3x more!
Agree but it’s also one or even the most expensive in the market.
If i am not mistaken, bro. SleeplessEyes did upload a YouTube video about the stress created by a weakening battery on other electrical components. I am not as good or knowledgeable as that guy but I think in that video did do the necessary tests to prove. Since I am not that intelligent I will just take the readings from the tester, it is good enough already for me but it depends on whether my clients wants to believe or not, at the end of the day.
I just did a battery replacement for a Honda Civic after showing and giving the test report to the client, showing that the Starter Test was having problems. According to him, he had to jump start the car before coming to see me. When a good battery was replaced, the fault cleared up immediately when the Starter Motor was tested again.
Lets take another example, the previous generation Myvi infamous entertainment unit that will encounter the Black Screen of Death the moment the battery has started its degradation process. My client's Myvi the very same model thats under my care have not suffered anything at all because the moment the degradation process starts, the battery is replaced to avoid damaging the sensitive electrical components.
Old cars would not suffer much because lesser electronics but it is the new cars that sensitive. I will ask the owner of the Almera with the busted Starter Motor again like the age of his vehicle, has he changed the Starter Motor before etc etc. His Almera looked pretty shiny and in well kept condition and according to him, he seldom uses the Almera since he uses his 3 other vehicles more.This post has been edited by Roman Catholic: Mar 9 2021, 10:44 PM
