My 1997 Mazda 5 speed loses electrical power.

Question

One trip it is working fine, radio and gage lights all work and then for no apparent reason, the system will go dead and when I come back to the car the clock radio has defaulted to 12:00 and no stations and last night I thought I was stuck when nothing would work . Turning the key did nothing, like there was not even a battery in the car. Then the power came back on and the car started right up.

Answer 2

Sounds like you've either a loose or frayed wire or corroded wire or a rusty electrical system connection or even a burnt or melted wire.

First of I'd be checking the battery terminal connections to make sure their tight and clean keeping in mind that most electrical failers in vehicles are grounds.Then check the starter,alternator connections , plus open the under the hood fuse box and have a look at each fuse and relay making sure they are in solid and also try popping each fuse and relay out one by one check to see if any of the pins on them are corroded etc , plus I'd be checking the engine block ground too.It may end up a bad ignition or ignition related faulty wire.

See bec your vehicle is a 97 I'd be cleaning all of the contacts and connectors or connections I've mentioned by using a set of small wire brushes, small file and fine sandpaper.Plus I'd be checking the in car fuse panel too for bad connections or faulty grounds etc, also be changing and using new assorted  proper o-ring connectors and battery terminal connectors.



Hope that helps and best of luck.By the way I'd be sure to clean all the fuses and relays one at a time , plus keep in mind that it does sound like a main lead positive or negative wire or connection is at fault here and also a wire could be so badly corroded in side that it can cause these types of electrical failers too.
