I've changed the alternator as the old one gave up.
Its a spare that i had laying around- Now my question is that on idle it fluctuates between 14.1-14.3volts (measured on the obc)
When i listen to music (keeping in mind that i have a sub) the voltage drops to around 12volts. When i turn off the stereo it creeps up but fluctuates around 14v ish
I know its hard to say but is this alternator starting to give up too or is it just the load?
I was going to buy a new regulator as theyre cheap enough anyway and try that on the old alternator which gave up.
