I'm new to this forum, so I hope I can get some information here. I know there are some smart people out there that can help me figure out what's going on.
I have a 1997 Ford E-150 Mark III conversion van that I've spent the last year restoring and updating with new electronics. Here's my problem. I purchased a Camco RS-750 alarm system, which is the same as a CX2300 series Carvox and probably a few others with different names. I'm about to stab myself in the heart because of the amount of anger this install has caused me. First of all, the translation into English isn't very good. It takes a fairly good amount of "what to they mean by that" to try and figure out. On the first install the parking lights didn't work, the program functions wouldn't hold in memory, there was no (-) output for the dome light supervision circuit and other things would pop up, when I tried workarounds for the things that didn't work. I finally called the supplier an asked if he would sell me another control module. He said he would send me another whole unit if I uninstalled everything and sent it back to him. Well, you people know how much of a royal pain that would be to untape, unsolder and remove everything. I told him I would buy another control module if he would send it. He did and I installed it. I was in the process of testing all of the functions and everything was working when my interior door lock switches stop working. Lock or unlock, it didn't matter, no response. This Van has a Keyless Entry module which is mounted on the outside wall behind the drivers seat. It does not have a factory alarm system. I had to replace this module because the locks and the remote that controls the Lock/Unlock function didn't work. When I replaced the module, I said to myself, I should make an access panel for it. I didn't and it was a mistake that I'm paying for now. When the lock switches stopped working, I starting tracing all the wires. The wires that sent the signal to the RKE (remote keyless entry module) was getting the 12 volts for it to send 12 volts to the door lock motor. The RKE was not sending the the required voltage to trip the motors. I disconnected the alarm module from the truck, connected a battery charger, turned on the ignition key back and forth a few times tried the door lock switches and to my surprise they started working again. I then connected the alarm control module again. Everything worked ! The next morning the same thing happened. The alarm would not unlock the doors, but get this, The original key FOB would. When I opened the door the inside door lock switches wouldn't work. I have a full manual for this vehicle so I again started PIN checks, which lead me back to the Keyless Entry Module again. Ford manual says to replace the module based on the pin output test. So I started removing the wall panels to get access to the module. I removed the module, took the cover of of it to see if anything was visably wrong and there wasn't. I spent most of last night and this morning reading post from this forum. There was several articles about a Ford (Wake-UP) module for fords that would wake-up the Lock/Unlock switches and the keyless entry module so the switches would work. Again I reinstalled the keyless entry module and again it work without any problems. At this point the Alarm module is not installed. It seems that after several hours the keyless module goes to sleep. A few minutes ago I tried the inside lock switches and again they didn't work. I then turned the key to the start position but not far enough to turn the starter, tried the interior lock/unlock switch and they again worked. The Ford wiring schematic does not show a GEM (wake-up module) for this vehicle. Is there anyone that can tell me what I'm doing wrong or what is happing during those hours of non-usage that causes the Lock/Unlock interior switches to shut down. Again the vehicle is a 1997 Ford E-150 Mark III conversion van. It has Keyless Entry but does not have factory alarm. This was verified by locking the doors with the widow open with the key FOB and then reaching in and opening the door from the inside. No lights and no horn beeping. I hope someone can help me.
