viper 5902

Alright guys I need some help if possible. I have a viper 5902 I've been installing in my 1972 Chevelle for alarm only (no remote start). Everything is installed and so far appears to be function correctly however the starter kill isn't functioning. Can anyone help me figure out why?

H3/1 12v switched
h3/2 12v const
h3/3 not used
h3/4 One side of clutch safety switch
h3/5 Other side of clutch safety switch
h3/6 12v const
h3/7 not used
h3/8 not used
h3/9 12v const

The starter wire runs through the clutch safety switch (old car) and I have bypassed this using a fuse. The alarm goes off with the key is turned on but the starter turns. If I unplug the fuse the starter doesn't work, What am I missing?

I just checked the key side and car side of the starter kill and it's correct green has 12 volts when key is turned and purple has nothing.

Well I have to post a correction I do have my wires backwards I swapped the key side and car side but was being an idiot when I checked earlier. I'll swap the wires and try again tomorrow.

For that vehicle you don't need the H3/2 at all. With what you got hooked up your are 90 percent of the way to having the remote start finished. And if you don't want remote start then the only wires that need to be hooked up are the following:

Both wires need to be hooked to the out side (+12v when clutch is depressed) of the clutch as follows:
H3/4 Violet connects to the cut side of clutch output.

H3/5 Green connects to the other half of the cut side to starter.

Wouldn't I also need H3/1 for the alarm trigger when the ignition is turned on?

With the car being a carb car I didn't think the remote start would work too well and that's why I wasn't pursuing hooking it up (even though it looks like I partially already did)

If you would like that to trigger the alarm when armed yes. But if the door triggers are hooked up they would set it off first unless they climb through the window after breaking it, which the shock sensor will usually go off. Then they would have to have a key or you would need to leave them in the car. As the force to pull the key cylinder will definitley trigger the shock sensor. But that's up to you if you feel you need too.

I figure the more fail safes I have the better

I need more help. At this time I still can't get my starter kill to work. I have the wire's hooked up correctly but it will still start. I am thinking I have a problem with my alarm brain thoughts?

Also I am hoping to swap out the brain with my 5901 brain to see if that will solve the problem but I really don't want to do this so I'm hoping other people have ideas.

H3/1 MUST be connected, that's why the starter kill doesn't work.

   I believe I have H3/1 connected to a 12V switched source is this correct? I will have to double check this weekend it is actually hooked up but I want to make sure it should go to a switched source. Isn't this the wire that acts as the ignition sense so when the key is turned on it sets the alarm off? If it is then this is working

Yes to all your questions!

Howie my ignition sense is working when I turn the key on with the alarm set the alarm will go off.

I'll double check the H3/1 wire is getting +12 volts with the key on but just in case it is any other ideas?

One of your wires at the key switch will go live on ignition and start (cranking),
that's the wire you connect H3/1 to.

Ok so your saying I need to check to make sure H3/1 is staying at +12V while on acc and cranking? Perhaps it's only on +12V only while on acc?

I never said ACC and cranking, I said IGN and cranking.
Most ACC circuits will; dump on cranking.

Howie stupid question but can you explain the difference between ACC and IGN? I believe they might be the same in this car. Here are two things from the wiring manual (painless wiring) right now I think I have H3/1 connected to Orange (it's been a while I'd have to double check) Purple is the wire I spliced for the starter kill

What Howie is saying is the ACC will drop to 0 volts while cranking the car, Ignition will typically show around 10.5 volts cranking.

Buddy I follow what he was saying I'm just confused which wire would do what with my schematic and if my ignition wire does drop to 0 when the car is started what do I do?

I guess maybe I should be tied into the coil (pnk) wire for the ignition since it will be +12V whenever the key is on cranking or not.

ACC hot on ACC, off when cranking on when run.
IGN = off on ACC, hot on IGN, hot on crank hot on engine run.

Thanks Howie so any idea if I should be tapped into Pink or Orange? I'm thinking it should be the coil one since that would need to be hot for the car to start.

Exactly.

Thanks I'll look into it this weekend

I just thought I'd post a follow up. Howie was correct the wire I was using was drooping to 0 when cranking. I switched the wire over to the coil wire and the starter kill now works.
