viper 5704 alarm 1st alarm attempt

P.S. I'm in total agreement with racerjames here and of course soundsecurity. They had a batch problem with those internal starter cut/ant-grind relays going open circuit on the earlier 5901s also on the UK market Cat 1 alarms, same problem, it was an internal dry joint, sometimes worked when you tapped the case, not exactly acceptable to the customer though. Frankly I'd rather they reverted to the older external relays, at least you could get at them in the event of problems. Wiseman 118. Here's the work around for your problem if you still want anti-grind and starter cut:- cut_antigrind.bmp

Don't worry racer, I was doing my pretty drawing whilst you were posting so now we're all confused

Oh ok, it dawn on me previously but the recent correction makes sense. T connect the green wire (starter input) wire into the factory purple starter wire (that was reconnected to make one wire again), because it has 12v coming from it. The purple wire from the alarm wouldn't work b/c there is no voltage being supplied from this wire.Wiseman118

You're completely wrong, my add-on relay is exactly what should happen inside the 5704. Green is equivalent to 87a. This should constantly connect to 30 unless the alarm is activated. Then the orange at 85 which is a constant ground at 85 and the pink which goes to 86 becomes activated via hot wiring the vehicle. This disconnects 87a from 30 thus preventing the starter from working. In the 5704 green and violet should be constantly connected unless the ignition is activated whilst the alarm is on. In fact green and violet AREN'T joined in your unit which is what is causing your grief and yes it's an internal fault. Simply rejoining your cut starter wire then joining it to the violet from the 5704 will cure the problem.

Sorry howie,    Clicked submitted my post too quickly. I just saw your diagram and i have printed it out to use. I will work to this once i get home. Thanks for help.Wiseman118

Please don't forget the 1N4004 diode on the relay coil, band towards 86, VERY important. Education time. When a relay shuts down, it sends a "spike" back through 85 to ground, this can be up to 300 volts and it WILL fry the 5704! If I'm not believed, there's a way of testing this but it's extremely painful!

Howie,    I sat down to fimilarize myself with your diagram. I have 2 questions: 1. The orange GWA you are referring to is the orange wire from the 6pin, main harness (-) 500mA GROUND WHEN ARMED OUTPUT wire? 2. How do I add the diode to the relay? Do i solder it to a jumper wire, then connect / splice the jumper wire with the diode to wires that are on pin 86 and 85?Wiseman118

Howie,     Last thing I noticed, the relay in your diagram represents a 5pin relay, right? If so, there is nothing attached to pin 87. The reason why I ask, is I thought I may need to get a 4pin relay instead if a 5pin. I wasn't sure , so I just wanted to askWiseman118

1) Yes that's why I coloured the damn thing ORANGE. 2 Anyway you can that works! Solder to the terminals, crimp in with the fastons, solder to the wires on 85 and 86 etc. etc. I use first and second methods. 3) No a 4 pin is a switching NOT a changeover, you won't be connected therefore you won't be able to start. You must use a 5 pin, aka SPCO, single pole changeover. The more of these type questions you ask the more I worry that I'll be receiving an airline ticket shortly.

I will let u know when i am ready to buy that plane ticket for you, but I am not ready just yet. this is my first alarm, but i do a lot of FYI projects. I just ask a lot of questions to be sure I don't mess up. You know, the measure twice, cut once method....Wiseman118
