Basically my ute blew one alternator. I put another secondhand alternator in out of another ute, it was working perfectly fine in that ute.
Got it all fitted and got 10 kms down the road and it blew up in my ute. Before it blew the alternator light was flicking on and off if that makes a difference.
I checked all of the fuses and battery, they were working fine.
When you rev the ute the voltage of the battery goes down instead of staying at a constant voltage.
Any advice on this issue because i have no clue?
