viper 5704 comm issue

I wired the viper directly to the battery with the capacitor in parallel to the viper. no luck. is this correct wiring?

It's right, but that would be only one entry of possible interference for the source. It's going to be trial and error until you eliminate the source. Or hope that some one who has this exact problem shows up to give you the answer. You can try the other options on the link I posted.

What about something like this? http://www.newmarpower.com/Grounding_Noise_Filters/Grounding_Noise_Filters.html 25 amp and wire in parallel to brain

They should work as long as they filter the noise at the same freq. that is causing the comm. issue. If not you are back where you started. As the viper 1 mile SST operates at 900mhZ spread spectrum.

Great news guys. wired up the alarm in its final location as opposed to direct to battery and I re checked the remote start randomly the other day, and it comms fine now with remote start active! However on the other side of things, the siren will not chirp. I am getting 5 ohms of resistance between the ground and the + brown siren output pin on the brain. CHecked for any wire strand or debris in plug but nothing. unplugged the harness, test for continuity between the brain pins and the female plugs in the harness, all no continuity. What gives?

if you tap the siren wires directly to 12v and ground will the siren go off? if you send the alarm into panic mode do you get a solid 12v or higher from the siren output?

Siren does work to battery. Full panic mode does not send signal to siren.
