Over the past 2 weeks my alt has been displaying lower voltages when the engine has warmed up.
Following readings without any accessories on
Cold start - 14.2v
30 min running - 13.8v
1-2hrs driving 12.6-13v
Battery is holding charge/still being charged after every run at 12.5v.
Belts/pulley new within the year.
I had to replace the alt this summer after it burned out on a road trip. The original replacement was a Bosch AL9348X which at its hugest output 13.8v. I brought that back to my local LR mechanic and swapped it out for a different (same model) one which then just started to not work at all. Went to oriellys and bought an Ultima alt and that’s what’s currently in there.
While getting a new alt isn’t an issue (I have one on order), I’m interested what else could cause this. Doing a search on here returns some results but those all seemed be consistent low voltages the whole time. Mine is only after it heats up.
EDIT: rebuilt alt fixed issue.
