New battery but no power.
I put a new battery in. Started it and drove it a few miles to the store. All good. Returned to the car and no power. Nothing, nada. No lights, no horn no click when I turn the key. Took the battery out and had it tested. Just purchased that morning. Tested great. Thinking possibly a relay or master fuse ( if there is one). Just don't know. Any help appreciated.
Это хороший вопрос?
@Billy Simmons ...a battery can test great but have to be recharged. this sounds like an alternator issue not recharging the freshly charged battery that you had just installed.
if it were a fuse, you wouldnt have had your car start after the new battery was installed. a fuse either lets current flow or it doesnt. It could be a faulty/sticking relay, only if the battery tested after had a full charge still.... but not sure.
Ive only had a few car issues so experience is limited. i will concede to any other diagnosis given here.
