50 bucks for the swap is dirt cheap.Houston,TX

thats just what they are charging me to swap it out, i had to buy the 5900 unit.

For anyone who is wondering, the 791xv's wiring is EXACTLY the same they DO in fact only have to swap the brain/antenna/remote. The range is SOOO much better than the 791's too. The commands get back to the remote slower than they did on the 791, but that is probably because it has to travel a further distance. So anyone wanting to do this upgrade i'd say do it

not sure if i want to kill some dollars for a better range right now. alarm is just as good as the installer.Houston,TX

well i originally paid 193.00 for my viper 791 unit, then i bought the 5900 for 230, and sold my 791 for 240 :) so all i really lost was the 50 dollars to swap them out. Very much so worth it in my opinion.

Put your voltmeter or DMM leads on each of the two LED wires that you connected to your alarm, and read the voltage while the LED is on. If it flashes too fast for the meter to get a stable reading, you could try using a diode and small cap for a sort of peak hold circuit. Doubt you'd need to do that though, since you're just looking for a rough estimate to see if it reads 12V or 2V, which should be easy to tell.

ok i got the 5900 put in, and the remote still does not make any noise if i set off panic, or if the impact sensor is triggered. What kind of noise is this thing supposed to make as the alarm is going off? and does anyone know why neither of my alarms have done it?

i dont have anything like that to test the voltage, does anyone know what the voltage is for the "bright blue led" that comes with the viper 791xv/viper 5900?

i got a red led from a previous model and it was no where near as bright as the blue one... is there a specific one u are referring to? the red one i got looked exactly like the blue one only red.
