Hi, so I want to make my interior lights come on for 10 seconds or whatever when I unlock my truck, I have an after market viper keyless entry system (unsure of model number) when I press the unlock button and make my fog lights (which currently flash) stay on for 10+ seconds when hitting the lock button. I also want to make my auxillary button turn on the lights when it is pressed for a short amount of time... I figure I need a capacitor to store the charge but not to sure of which kind?

When I wake up I can gather more info about the viper if required (I haven't actually managed to locate the system yet except I know it is somewhere near the steering wheel).

Thanks,

Ollie

You shouldn't need a cap if you have a good battery/charging system.

Now...some alarms have that feature built into it. I've only done a couple over the years, usually a soccer mom. Lol

Look into the alarm before you do anything first

So Viper are very stupid with this model 211HV, the interior light circuit within the system is a 30 amp circuit so it blows my fuse EVERY TIME!

Reduce it with a resister

I just need to work out the required resistance and I'll be good to go.

Umm, no. That's all incorrect. That is not how electricity, capacitors, resistors, amps, or volts work. Do NOT do any of that.

If your alarm system does not have this function built in, you will need to add something on yourself. You can get pre-made time delay relays that are self contained. You can put it on the parking light or fog light output from the alarm.

I will find one and post a link when I get home.

Ok well it does have one built in HOWEVER it outputs 30amps to the dome light which is fused at 15...

No it doesn't. That is not how amps work. Amps are drawn by the device, not pushed by the source. Your dome light draws maybe 1 amp.

You have think about electricity like a pluming system, Volts is the pressure in the system and amps is the amount of water in system, so that said, the alarm system will support a maximum of a 30amp draw and the dome light circuit a maximum of 15amps at 12vdc so the dome light maybe draws 10amps if that, and that seems a little high although that circuit may have some other accessories on it.

A circuit will only draw as many amps as it needs to function.
Here's an example, A car battery typically has 600amps at 12vdc and if you touch the terminals with your hands ,nothing happens yet if you were to touch a circuit 220vdc at 1amp you would get knocked on you ass, I guess what I’m saying is you open the door and the dome light comes on 600 amps from battery is available but is only using what it needs to come on...

Simplicity is the ultimate sophistication.

Torque it down till it breaks off, then back it off 1/4 turn.

First of all, I’m surprised at the level of electrical understanding. Secondly, to make lights come on for 10 seconds is fairly simple. When you unlock the car, the central locking system sends a signal to the locks, you can use that signal and feed it to a relay and use a 555 timer to time it to 10seconds. Connect the relay to the lights and feed it a signal from the timer. As soon as timer gets a signal from the locking system, it’ll keep the relay on for 10seconds. This is how electronics work.

Sorry I forgot to send you the timed relay you would want. I used this frequently rather than building it myself.

Board has all the connections, timers, and options with a built in relay.

Give me a house and I can wire it up, Give me a building that needs and alarm or cameras and I got it. Give me a bloody truck and some lights and I get too confused! My problem was this: I do NOT know what kept popping the dome light circuit fuse after I connected the interior light to it... I followed the instructions for the device and blew 3 fuses so gave up and started thinking like an idiot!
