Help diagnose starting issue. Battery/alternator?
Hey guys,
Car used to start straight away and crank hard. Last few days when i turn the key, it starts to cranks slower and weaker, progressively getting worse
Didn't feel like it would start the next day, so last night i charged the batt just to see if it would fix it.
This morning multimeter shows 12.3V engine off, got it to struggle to turn on (video 1) and showed 14V
Turned car off, wouldn't start again. After a few tries, battery showed 10V
Now it's stuck there, when i try to start it (video 2)
I dont think its the starter motor as it appears to be turning fine and the cluster lights turn off when i turn the key so more likely to be batt or alternator?
turn sound up for the vids and you can hear when it cranks
