Hello,
Have been brainstorming for a while on that one without cracking that nut, so looking for some help/guidance.
Driving a PZJ70 from 1993 in Costa Rica, where it is >25C most days....
It used to be that we would wait for the glow light to go off on every morning before starting the engine and then never bother for the rest of the day. About a year ago, it started to have some more trouble to start after the first morning start.
For example going on highway for like 1h, stopping to fill up the tank and we would need to glow again for the whole glow timer, otherwise it won't start. When trying to start too early, it would act as if the battery is almost dead, very slow/painfull rotation by the starter. Going for another full glow timer duration, and it would start easy peasy, like the battery is back to life! Obviously the engine was still hot, and the battery is the same...so why?
Have been looking here and in some other forum and did some test today with my voltmeter.
When the key is on the glow position, i measure 10.2v on the glow rail for like 6s. Expected.
After the glow light goes off, i still read 10.2V. is that normal? I was expecting lower or even 0.
While we go to start, then it fluctuates between 8 and 6V until the engine goes and then it is 0v.
I am puzzled and would like to understand why the glow keeps on going after the timer(6s) and if it is normal. I was suspecting at some point that the glow was taxing the battery and preventing the proper start, but it seems that it keeps on going anyway, so not sure where to look now.
Any ideas of what to test? What to look for?
Geraud.
