Hi all,
First post on here, or anywhere for that matter.
Recently purchased a 90 model skyline and in an endeavour to keep it mine decided to install an immobiliser myself. I opted for a "VISION VAE 315-950" being all black wiring, Aust Standards and the right price (unused but 2nd hand). Install was going great untill it came to testing. The unit is designed to self arm if the car is not turned on after 40 seconds of being disarmed. the problem is it will disarm fine, can start the car fine then 3 seconds after starting the LED indcator turns on solid through till the 40 second mark when the immobiliser will rearm itself and shut the car off (starve of fuel being fuel pump and starter circuits cut). I can then disarm the immobiliser and start the car and go through the same process again.
This immobiliser is an immobiliser or full alarm system. It can be changed from one to the other with some turns of the ignition. So I tried to hook up the door trigger thinking it had to be working for the immobiliser to function correctly. It doesn't suggest this in the book.Is this the case with other immobilisers?
Anyway it was meant to be a -Ve feed wire (door trigger) so i rigged up a quick extention to hook it into the door plunger switch and it didn't seem to make a difference. I later found out while scratching head, that the door trigger feed from the alarm box was actually a possitive wire! So I have now fried something in the circuit between the door trigger and the interior light because it doesn't work anymore!! (passenger side still works fine so not fuse). Tried to program it from +Ve to -Ve with some ignition turns but it doesn't register or confirm that I have programmed anything! I'm getting so frustrated cause I can't think of why it would be doing this. It seems as though you can disarm it, start the car but then the alarm unit doesn't register the the car has even been started so arms itself again.
I know these alarms arn't very common, in skylines anyway, cause I haven't heard a single mention of any VISION products in the copious amount of posts I have sifted through.
Can someone with extencive troubleshooting knowledge please give some usefull possibilities as to what may be amiss? I don't have great understanding of electrics. Just a very curious approach to things.
Oh and everything is hooked up as per the instruction (very loose term) booklet. I think (shrugs shoulders) Thanks in advance for any assistance.
