I'm starting my stealth alarm install on my DD and I was wondering how often should a relay be replaced? Yes, I understand when one malfunctions it should be changed, but how about changing it once a year? once every few years? I was thinking something along the lines of like maintainence to keep your alarm functioning smoothly? I mean, I would hate for a relay to go out on me in the middle of the night in the middle of nowhere.

well.. i'm sure your car has room for couple extra relays to carry around for when you happen to be in the middle of nowhere. now, if relays inside alarm brain fail, you may have trouble replacing them in the middle of nowhere. if thats a concern, don't wire to kill any vital components through your alarm.

 

As long as you are using a good quality relay, it should outlast the car.

Most common cause of relay failure is not installing a diode across the coil terminals, #85 and #86, the diode will limit "arcing" at the contact points.

I have had a pair of, [un-dioded] Bosch relays for the power door locks in my 94LS since it was new, [late 93] and they still work just fine. 94
