This Listing is for 3 x Saab alarm repair capacitors.
It's not always a internal battery fault when the alarm fails,
although, it is the norm, but sometimes 1 or more of the electrolytic caps may have failed.
If any of the caps have failed, then you need to replace them.
These capacitors are found in the Saab 93 (9-3) & 95 (9-5) Twice Alarm Siren.
Each component is the correct capacitance for the alarm.
Thanks for looking.
