I have the factory RS 3000 alarm with the flashing LED status monitor in a 1998 4Runner. I recently upgraded the radio trim piece from a later model which also includes an alarm LED. My question is would having two flashing LED's drain the battery say if the vehicle wasn't driven during a two week vacation. I'm no expert on car electrics and apologise if this is a dumbo question.

 

I wouldn't worry about it.

LEDs are used because they draw a miniscule amount of power to operate. I would be willing to bet that you couldn't drain a good car battery down with two LED's in two years. You'll be fine.

Now, that is assuming that you have nothing else in the alarm drawing power. As long as its just the LED's, you'll be fine.

 

its quite alright, the only way to know is to ask. you will be fine with those two LEDs, they wont drain your battery out, esp not in two weeks. they have a current draw in the miliamps or smaller area, which is about as much as your 4Runner consumes to remember user settings and data, such as the clock and the ECU. if it dies, and it was purely because of the LED's, then either you got something wrong elsewhere or you left a light on without knowing.

best of luck, and enjoy your vacation!

 

Thanks for the confirmation guys.

 

think about this... those NINE led flashlight can run off 3 AA batteries for HOURS and HOURS!!

 

All academic as I plugged the original LED back in and the new one on the console stopped working. I can only assume that the alarm ECU can only send a pulsed signal strong enough for one LED??

 

That is a posibility though it may be that the box is only looking to flash one led. are these leds wired in series or parallel? in series the resistance of the first led is taking all the signal power. If they were in parallel they both might flash but at a slower rate.

 

Mmm my electrical knowledge is lacking here! Would need to do some Google to find out diff between series and parallel. What I did was tap into the two wires feeding the original before the existing LED . Although the new connection is first it goes out when the the original is reinstated.
