viper 5902 in 1999 ford explorer

That is pretty odd. I'm leaning toward a bum unit. Without a second one to try and see if the same results occur I am out of ideas.When all else fails, Read the Instructions

i still think i have or dont have something connected right. i had everything except the remote start working on thursday of last week and i unhooked it to run the wire to their "permanent" homes and it has not worked since so i think i am missing something just dont know what it is... i dont think its a burnt unit because everything is connected with the battery disconnected... grrrr lol i wish i knew what i am doing wrong.. But thanks for your help though Smokeman1!NExtelmike

If you disconnect the starter output wire H3/4 Violet does it show 12volts on it??

Maybe time to step back and recheck all of the wiring with the DMM.

Without H3/6 hooked up H3/4 has steady 12V when i connect H3/6 the brain starts clicking like crazy and H3/4 has flickering 12V...NExtelmike

H3/4 should not have any voltage on it until the remote start is activated.  I just bench tested a Pyton 872 to confirm this. Wiring for this is the same as your 5902.  With H3/2, H3/6, and H3/9, connected to 12 volt source, no voltage on the Violet starter output wire.When all else fails, Read the Instructions

So what does that mean? Do i not have something grounded somewhere? How do i fix this?NExtelmike

This is the issue i am having now is if H3/1 (pink) is not connected to 12V H3/4 has pulsed 12V which continues to crank the starter... on a positive note i got the parking lights to work but still no door locks or anything from the command center... i really appreciate your help Smokeman1NExtelmike

Pink H3/1 should NOT be connected to a 12 volt source, it gets connected to the ignition 1 wire on the car.

I am thinking you have some wires crossed.

From your last comment pink not connected to 12 volts tells me you have connected the wires incorrectly.  You need to verify the wires with a DMM
