#is this normal when charging battery

Hah. Never seen that before. What kind of charger and what is the age of the battery?
@copper nacelle just a standard battery charger not sure. Battery is a few years old but it’s good
GG @reef lava, you just advanced to level 6! Chat more to level up and earn top roles!
My alternator is broke tho so maybe that has something to do with it
Is there an amperage rating on your charger? Look for something like 1.5A or 20A.
Ok that should be reasonable - I was worried it was like a 50 amp one and was overcharging your system. What’s the car doing/not doing that makes you suspect your alternator is not working and, similarly, the battery charger working fine last night but now it’s not? And is this a late 90’s Taurus/Sable? What are the conditions of the battery cables, especially the ground from the negative terminal of the battery and the other end where it goes to either the engine or the chassis?
take the battery out of the car and charge it @reef lava
you are witnessing the reason why you’re charging that battery up.
power is going through the ECM and to the alternator (which it shouldn’t be doing) and it’s causing your lights and internal components that run off the alternator to sap all the power off the charger and flicker like that.
@fathom steppe is it doing that because my alternator has failed? Was reading 12 v when I tested it
@copper nacelle alternator was weak giving off 12 volts
And it’s a Jaguar x type 2006
x types have all sorts of electrical issues from this model year. just because it’s cool and cheap doesn’t always mean it’s a good car. as things get old they wear down and start suckin
What seems like most correct here is to take the battery out per @fathom steppe recommendation and charge it without it being connected to the car. Fix the alternator. Then you’re probably ok, but there’s still a possibility that you have a cabling issue and it is no guarantee the battery is good. May want to get it load tested while you have it out.
this guy knows his stuff!!! i just make dangerous assumptions that could get people killed (i tell people that the parking lot is over there)
Parking lot?
