shock sensor problem

i've got a viper 790xv alarm. one problem i've had since i've installed it is that the shock sensor will only set the alarm off when i hit the truck pretty hard. i have not once been able to get the warn away to work. i think my wiring is correct(just plug the cable into the sensor and the brain??) i would love to get my warn away working because right now i've got to hit the truck pretty hard to set the alarm off.

Have you tried to adjust the sensitivity? There should be a small dial on the shock sensor.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

yeah, the adjustment barely does anything, even then the warn away doesnt work.

Move the shock sensor to a new location. I like firm wire bundles.Certified Security Specialist

its on the steering column right now. where would be a better place?

i also have a question on the wiring. in the manual for installing the alarm, it showed a picture of one of the wires cut off at the end going into the sensor. the wire that came with my alarm is all connected.

Mount it to a stiff wire bundle. The other sensor is optional and nothing needs to be done if you don't have one. Certified Security Specialist

The wire only gets cut if you add a DEI dual stage radar or a second shock sensor. You only cut the wires if you add an optional, additional, sensor. There is nothing wrong with the way it is wired out of the box.Certified Security Specialist

The first thing I would do is varify that the sensor does indeed operate normally. Remove the sensor from its current location and hold it in your hand. Arm the alarm, and tap it with your finger if the unit does not pre-warn. Turn the sensitivity from full left, to full right and try it again once more. There are times when the resitive pot falls in a dead spot, or the maximum degree of turnning radias is not properly aligned on the pin which reduces the sensitivity, so try that. Next, varify that your alarm CPU settings are not set for a dual sensor alarming / tripping. If it is, the alarm will never trip because it is awaiting for the second sensor to follow. Normally this applies to only the full warn cycle, but I have seen this affect the pre-warn feature for some odd reason. As Auex stated you should also move the unit to ensure a more uniform reaction to impact / shock. Everyone has their own method as to how to secure the unit to the vehicles chassis. I prefer to screw the sensor(s) in place in a central location which provides the most uniform sensing. Many use wire ties, double sided tape, or velcro. The down side to the last three is a reduced amount of sensitivity. You can always reduce the amount of captured sensitvity by turning down the unit or moving it's placement, but you cannot increase the units maximum capture sensitivity rate as it is preset by its design. If all of the above does not work, consider having the sensor replaced. Regards EVIL Teken . . .
