Hello all,
I replaced my original 13 yr. old Delphi alternator with a re-manufactured Delphi. Battery is a couple of years old. I decided to replace the alt. because SEL kept showing electrical code & the TB has stalled a few times in the past when accelerating from a stop. Fuel pump as been replaced along with fuel filter. After replacing it, let it idle for 30 min. - instructions say 20 min.... The entire time the voltage gauge is fluctuating from 14v & higher, especially when holding idle at 2k rpm. The cluster board & electronics, lights (interior/exterior) fluctuating at the same pace. All the codes cleared after I did replace the alt. though.
Could the battery be bad now from the old alternator? I know it acts as a filter in the current wave cycles, right? Maybe I'm seeing the current waves spiking indicating a damaged battery.
Thanks in advance fellow backyard mechanics !!
Mike
