Hello, hope you might be able to point me in the right direction (cupra mk1 auq)
Alternator bearing was on it's way out clunking and whirring heavily so replaced it with an RTX 120a model (cheap basically).
Was fine for a few days but now in the morning my battery is completely flat. No clock or dash lights etc.... Car won't even unlock. Tried a new battery, leaving it unlocked overnight and no success. Battery is charging at 14.39v.
Could the unit be draining the battery?
My next step is to put the old alternator back in and see if the issue happens again. If not is it worth getting a better quality replacement?
Thanks for your time - Dan
