Viper 5900 SST Parking Lights Won't Flash

Viper 5900 sst on a 96 f150 5.0 xlt it would work fine then it was intermittent now it dont light at all. All fuses and wiring still looks good is the brain acting up or could it be something else? Everything else works as normal.

Well now its doing this still and now it the heater/ac wont turn on until i get to the vehicle and put it into the ON position. No one experience this before??

youre not powering up an ignition or acc wire then.Ted

So its just a wire loose and not just my brain slowly dying? Wish I could find a 5900 SST Brain to buy to test it. Its 6 years old I may just be due for a new one.

Use a meter and test the outputs, see if they are functioning. the 5900 brains are the better built brains-haven't see any go bad yetTed

How do i go about testing the outputs place the meter then activate each action or what sorry im a novice man but if you could tell me more? Thank you by the way.

If you have an issue with the ignition not turning on, i would check the fuses first. Replace any blown fuses. They are usually green 30amps fuses on a Red, RED / black, RED / white wire. IF that does not work, time to pull out a test light or multimeter. Test light black to ground, and red to the wires you want to test. Activate the starter and check the ignition, start and acc wires. Same applies for the dmm, which will register 12v when activated. constant always hot ignition hot during remote start acc hot when activated, shuts off for 2 seconds and back on constantly start - turns on for 1 second, shuts off.
