viper 5902 + dball in hyundai 2012

Yes, safer than trusting to luck and crossing the fingers, touching wood etc. Don't worry about my rambling, all good old Christian expressions for luck.

What do u think about the defogger issue?

No idea and I'm going to bed

OK, thanks, good night

I have installed the 508D and 509U successfully, tested them alone and every sensor of them has a toggle switch (on/off) to the red wire. and the 516L and it is working with remot start, arm, disarm and everything. Didn't install the tilt sensor 507T not 504D nor 506T until i figure out how to deactivate it when remote start and install toggle switch for them. Changed the relay diodes from 1N4001 to 1N5004 400V protection and 3 amp. Is that relay fine? I have one thing not working in it. When the 508D gives signal to Viper warn away i get it on my remote, but the 516L doesn't announce the warn away message. Do you have any ideas

Actually too much, change them back to 4004* please. That might be the reason the 508d isn't triggering warn away. When on, if you get very close do both the green and red LEDs light up. Lastly wait about 15 seconds before you try and trigger it and have you adjusted the screw pots yet? Very fiddly. *Needs more current to get past the 54XX diodes ??

Forget the 516L; wire directly to the alarm, tell me if the 508d works then. You should know by now I think the 516 is rubbish.

the 1N5004 is only used on the power of the relays, the 508D has a 1N4001 connected to it, and test the diode polarity with DMM. Cathode towards the sensor. 1N4001 is used on all signal wires only 1N5004 i used it on the relays as surge protection only if i get very close the red LED only lights up and the alarm is fully triggered, and if i am a little far the green only lights up and i get warn away alert on my HD SST 2-way remote. Yes i adjusted the outer (warn away) zone first then the inner (trigger) zone. And the 508D works fine with good range.

All sirens are working fine and chirps too. Just still from time to time i get "brake on" on the HD remote when i start to remote start and if a wait a min or so and try again the remote start works normally. Even when i am very far from the car.

Try a "power down and reboot" on the 5902 that's all I could think of ref. the brake switch. Do you have LED rear lights by any chance? As for the 508d problem, just try by-passing the 516L and go straight to the 5902, tell me if works then.
