John is saying alternator is because the voltage reg is sometimes built into the alternator (and I wouldn't be surprised that on newer models it's just a part of the software??) ....New parts don't guarantee it's actually in perfect working condition these days , rebuild places are not all created equal. Get a parts place to test it if you can. Might have a warranty on it ?
And about the spikes . The battery will probably just ignore them but a vehicle computer might not be so forgiving.Then again , a computer glitch might be the culprit ?

Double checking wiring terminations is unfortunately an ongoing maint. item on old vehicles so still do that .

And for anyone wondering . Post repeats after doing an edit are noted , the posts before an edit have been /will be deleted . (Software glitch example arrrrgh)
Anyone seeing any other post doubles , please let me know .
