Domelight Supervision Not Triggering Relay

The output is damaged. If you wont get the seller to swap the brain then I think you would be better off just replacing the brain only. The cut wires aren’t really an issue since you would just keep your installed wires intact and send the brand new wiring harnesses back with the defective brain unit. If you buy just another brain unit then it’s about $40 or cheaper if you make an offer. I just searched eBay for 5x05 Avital and found one.Steve G

So I agree it's likely damaged but what I can't figure out is how it's still sending a signal. I checked the ma reading on the trunk signal and got 0.14ma and the dome signal got a 0.12ma reading. I just keep thinking I can make it work. Admittedly I'm a bit retarded at times though. :D

Alright so an interesting finding. With the transistor wired like pic 1 and the relay all setup correctly I unlocked the alarm and was checking for continuity across the collector and emitter. In the process I accidentally bridged the base (currently receiving signal) and the collector. Low and behold the lights came on and stayed on until the signal quit after 30s. So I tested that again by unlocking and immediately bridging the two and got the same result. So the signal is strong enough to keep the relay triggered but not strong enough to trigger it initially.

Needs about 130mA to trigger and you tested 120mA. The trunk gave you just enough to trigger but in reality they should all be putting out about 200mA. Just for the hell of it double check that you have the unit connected to a good solid ground. Scrape away any paint if necessary. http://www.mobileinformationlabs.com/How%20To%20Guides/Relays/HowTo-Relays_understanding_Intro.htmSteve G

Good news. I ordered an ssr and that solved the problem. Works perfectly now. Still needs the transistor but not a big issue. Thanks for all the help.

can you please explain how the SSR resolved your issue and now it works?
