#1 Most Common Remote Starter Installation Problem
After 30 years of being under a dash installing everything from old-school kill-switches, anti-theft coded key-pads, auto alarms and later remote starter systems, there's not many problems that I haven't seen, heard of, read about in manufacturer's technical bulletins or actually caused myself, that installers I've provided tech support to over the last 17 years that have reported a new installation problem to me;
So, that being said, in my experience, I have to say that the #1 problem that I have found to be the cause of a "oddly-working", "barely working" or "blame it on the system, not the installer" problem is due to a faulty or bad chassis ground to the system...
It's not as easy to find and confirm a good negative -12V chassis ground source in a vehicle as it is to locate a positive +12V source. Simply put, most ground sources in a vehicle fluctuate (and I'm confident that most professional automotive audio installers can testify to this statement). This is why you can't tap into any existing factory ground wires in the vehicle, dash support brackets or most steering column supports either.
Without indepth explanation (I've learned it's not so much what's causing the problem, it's "how to fix it"!) alway's use a self-tapping screw through any metal that is painted the same color as the exterior of the vehicle. Example places I personally place my grounds; behind the left kick-panel or on the firewall. And don't over tighten and strip the self-tapping screw!
