1990 festiva blows 10 amp but blows fuse after engine staetsfuse everything woeks fine with key in on position
Get a wiring diagram & see what is on that fused
circuit & work that circuit. Leave the fuse out at
first & make sure only that fuse & circuit is involved
When a car gets over 15 years old, then & only
then, do you start to have fuse issues as wiring,
connections,relays,switches & devices using electrical
current, start to get loose,corroded,& develop resistance
I would remove & clean every ground wire on the car you
can find
Both ends of the battery cables as well
Do voltage drops afterwords on cables
Check for alternator diode leakage or what
is called a/c ripple
Check for current draw by putting an amp meter
in series with either battery cable & wait for things
to time out,make sure you leave the doors closed
& allow at least 10 to 15 min.
You shouldn't have over 50 to 70 milli-amps
Just the clock & computer memory & some keep
alive items
Don't keep replacing the fuse,that is not a fix
