viper remote issues

I had a Viper 5901 come in today with remote problems. DEI's fix is to solder in a 5k-10k ohm resistor on the blue wire in the antenna cable and delete all remotes to the brain and reprogram. I think that is a little unnecessary.Big Al

why are you affraid to use a test light?  the only pins you are supplying ground to are either negative inputs or negative outputs.  with the exception of maybe the white parklight wire pin which does not see 12 volts until the unit is activated.  if you think it's bad to ground (-) ins or outs then don't do this.  otherwise, last week i did this again on a 5901 viper and it worked yet again and no the unit did not fry, just leave the main harness plugged in and that's all.  i would not post this if i fried something.

I'm so with p/tinstaller here.  I've been doing this work since the 1970's and I still use a Snap-On incandescent test-light.  I realise what we try to teach novices about correct practice  but I've never found anything better at sniffing out door contacts or working out how the lock triggers work. Yes when I'm unsure especially on a newer vehicle or testing resistive wiring  I'll use a DMM,  I also use a Mac 120 test tool with LEDs,  its wonderfully  fast for finding tach,  just watch the LEDs flash!  In the application you were using an incandescent test light would probably have been the safest as the bulb acts as a buffer. It's also faster at finding the mute wire on a head unit.

I'm having the same problem but with a Python 872.  Remote received confirmation until a couple of months ago.  Replaced batteries, didn't work.  Got a new remote and programmed by a different installer (original install by Circuit City) still no confirmation.  I am not an installer, but was going to have a friend look at it.  Will the suggestions here work for the Python or will my friend have to do something else.  Also, I don't have the install manual.  If anyone does, could you post it somewhere.

Thanks

i have found that they need to be "rebooted".....  2 ways to do this are to disconnect the vehicle battery for a couple of minutes or else pull the 15 amp fuse on the red wire of the secondary harness which powers the brain (this is usually what i do)   then they work fine again... a PITA, yes... but a quick fixKevin Gerry
