PAC audio TR-7 module.

any guys out here used this to bypass the alpine fortress so they can access DVD and Menus (ie setup functions).

I had purchased one......installed it to the directions and voila it worked. was able to set my clock and change some of the frequency and hertz settings.

everything was working great on saturday night after install. and when i started my truck for work this morning my setting features had been blocked again.

I checked all my connections and they are good and tight. i have power to the module. the red LED is on.

now i have 12v(switched)
12v on the remote wire (blue)
but only reading 4.9 v on yellow/black wires and 0v on yellow blue wires.

almost as if it is not pulsing properly.

do i need to reprogram or do uthink i have a faulty TR-7
like i said i worked perfect for a couple hours.

thanks for your input.

i haven't played with it.
i've seen it. co-worker bought one, or similar from pac couple years back.
said it worked like a charm. never really heard that he had any problems with it.

i did a little reading on it. but i would try reprogramming it and see if that fixes the problem.

Possibly cold solder joint?

I used one on my last Alpine system, worked great. I've reinstalled that system in 2 different vehicle since and still no issues. Have you tried to simulate the pulses that the TR7 outputs by taking the Alpine input wire off of it and just going direct with that wire touching it momentarily in the sequence required?

well i give up. i phoned my local audio shop and have made an appointment for saturday to get this figured out. personally think i have a bad TR-7 module. and they have put a new one aside for me. this shop has always been helpful with my own mess ups all the way back to my mid 20's and banging my 4 12's in the 93 ford f150! its nice that they remember someone that spends 3000 on car audio in one shot even after 9 years! will let you know how it goes next week.
