I have a infiniti Q45 95 model if i charge the battery it will start but nothing electronic works what is it?

Question

It will run when the battery has charge but still nothing electronic will work does this have anything to do with a relay or altenater

Answer 1

Check the large fuses (fuseable links) on the positive battery cable at the battery. These will blow if someone jumped the battery backwards and the symptoms sound like what you have.

Answer 2

Infiniti Q45 is junk. It just goes to show, You Can't Polish a Datsun!

Check the fuses under the dash... theres 1 fuse that controls most of the electronics, it's labeled ELEC.

Answer 3

relay, fuse or an alternator cable.

If the battery gets charged, then the alternator itself is okay.
