+12 V Battery/Constant Fuse?
Ok first the issue. I have a 1992 Sentra and the dome light, trunk light, hazard lights, constant +12v wire in the radio harness doesnt work and the clock in the cluster resets every time I open then close the door. Oh and the warning buzzer that the key are still in ignition doesnt work either. I've been trying to figure out what could be the issue, all the fuses there under the dash seem fine, but then I came across a post on a Subaru forum where a guy had a similar problem in his car with a bunch of thing like that (that require constant power even when car is off) not working. Someone suggested that it was a 20 Amp fuse under the hood somewhere labeled "Backup" that must have blown. Is there any fuse or something like this that i could check for to see if this is my issue as well? I'm really confused at whats going on. Once when i removed my old (stock) tape deck, i plugged in a aftermarket head unit and the dome light and clock were working again but I was only testing it and when I went to try again with another head unit no dice.
The only way i got the head unit working this time was putting both the constant and switched [meaning power goes thru when i switch on the ignition] wires from the head unit to the [blue] switched wire in the car as the constant [red/black] wire didnt seem to have power coming through it.
Any idea whats going on here?
