Hello, any help will be greatly appreciated. Installing a Viper 5002 in my 36 Ford Street Rod. I have 2 aftermarket two wire lock actuators. I originally wired one actuator by using diagram D shown for aftermarket actuators (violet to 12+, white & brown to ground, green & blue wire from alarm to actuators) and lock seam to work fine. I than proceeded to add the other door and than some happened where it worked a few times and then nothing. Did I fry something or does this have to be hooked up an other way?

Thanks, Dave

Actuators / Reverse Polarity

This is practically identical to the 5 wire alternating 12V(+) system above. The only difference is there's no switch! Both motor legs rest at ground at the relays. To lock or unlock the vehicle, polarity is changed on one motor leg.

Thank You, that looks easy enough. How do I add a interior switch to this?

See the 2 connections that say alarm unlock output and alarm lock output? Simply ground the appropriate wire via a momentary On-Off-On rocker switch. Simply ground the middle terminal of the switch and connect one switch terminal to the alarm lock output wire, this will lock the doors. The other terminal of the switch connects to the alarm unlock output wire this will unlock the doors.

Hello, I need some more help. The above relay diagram works great, however the relays being energized kills the battery when car sits for a couple of weeks with out being started. Is there a way to fix this problem?

Thanks again, Dave

The relays are only energized when you locking or unlocking the doors. when energized they pull 160 Milliamps of current each, they only energize one relay at a time. If one of them was staying energized, this would run your battery down in a couple of days, unless of course your streetrod has a bank of about 10 batteries. I am sure that it is the alarm system that is running the battery down. Even disarmed they do pull a little current, most vehicles are driven daily or at the minimum once a week or so. The reciever inside the brain has to run so it can look for signals from the remote.

This should not happen. If the relay is staying activated (latched) there is an error in the wireing.

Understanding "how" a relay works will give you all of the answers you need.

He was thinking that the relays were running his battery down. It takes 3 weeks or so to run it down. I was just telling him that if the relays WERE pulling current, the 160MA of the relay would run it down in a matter of days. That is not even taking into consideration the amount of current the actuators would be pulling.

Yes, when I put 12 volts to the relays they click and stay energized. I believe this is what is draining the battery. How do i fix this problem?
