    Default 9500ix issues

    So i have had my 9500ix since august or so. I have it hardwired and have never had any problems with it since about a month ago.

    The problem that i am having is under heavy acceleration the Laser alert will sound. The only difference between before and now is more Horse Power. I added long tube headers and a completely different gear in the rear end. The overall difference in acceleration is huge.

    I called Escort to get an idea if it can be fixed. The woman on the phone said that Escort has encountered this problem many times before... she said in fact hers does it when she backs out of the driveway. She said it is triggered by odd little things like the low hum given off by high HP cars, or the windshield wipers, or in her case the back up sensor. She said is it really a problem?
    I said yea its kind of a problem being that the main time i would need it is under heavy acceleration. She asked me if i was sure and i assured her i was sure. She said the only way to really fix the problem is to lower its effectiveness by 50% or so...

    I guess my real question is... is anyone having this problem as well? Does anyone have an idea for a fix? Only under heavier Gs does it go off. I walked threw the problem with REBinc already as he is on my forum as well and i cant seem to figure it out... i don't think my car is giving off a different hum than it was before... and people with the same application don't seem to be having the same problems!

    Thanks in advance,
    Brad

    Hi Brad,

    Welcome to the forum!

    I think that the problem is caused by either one of two things, or by both things. These things are power and electrical noise.

    First, check that your RD isn't vibrating when you rev your car engine. If it vibrates excessively, then this will cause sunlight to scintillate through the condenser lens built into the laser IR detector diode. You can rule out vibration by simply holding the RD in your hand and then revving yor car engine up and down. If you get laser falses while holding the RD in your hand, then the problem is either poor electrical connections or electrical noise caused by alternator whine, in which case you will have to proceed through the following checks:

    Check your battery's cable connections, including the other end of the ground cable where it connects to your car's engine block and to the chassis. If these connections are a bit loose or corroded then vibration can cause all of your alternator's hum to suddenly become very strong throughout the rest of the car's electrical system since normally the battery helps to sink the alternator hum.

    Next, check your hardwire installation. In particular, check all crimp connectors for power and ground, and check that the ground connection is solid. Where are getting power from? I assume a fuse tap in your car's fuse box. Try tapping power for your hardwire into one of the heavier amperage fuse box terminals. Why? Because these heavier amp terminals feature heavier cables which lead back to the battery, which usually means that they are much more free of alternator noise (whine or hum).

    You can go to your local Radio Shack and get one of their small snap-on RF chokes which you will snap on over the power lead of your hardwire install. Wrap the power lead around the RF choke twice and then snap it together. Its quite possible that this will reduce electrical noise enough to stop the laser falses.

    If the RF choke greatly reduces but doesn't totally resolve the problem, then you will need a cheap but good noise filter which are commonly used for car stereo installations. These filters have both a choke and a capacitor inside of them. Any cheap car stereo noise filter which says that it will attenuate noise by at least 35dB should do the trick nicely. You can pick up one of these filters at a local car stereo shop or even on fleabay. You can even scavenge one of these noise filters off of an old car stereo. Don't accidentally wire one of these filters up in reverse. Power and ground from the car enters the filter through a pair of power and ground leads (usually red and black) on one side of the filter, and then the filtered power exits the other side of the filter via another pair of wires (usually orange and black).

    Well, there you have it. Track down and fix the problem!

    X2.

    But all he needed to say was:

    Check all your connections for the RD and battery and try an RF choke which you will wrap the power lead around the RF choke twice and snap it on over the power lead of your hardwire install.

    JK, we love you MEM-TEK.

    Pfft. I'm must me. If you all aren't careful, it will all go to my head and turn me into a obnoxious know-it-all. That would be bad-bad.

    I had the same problem with a few of my 8500s (but much worse though.. to the point I couldn't keep laser function on.) Escort gave me option of sending the unit in for extra shielding for a cost without any guaranty that it'll actually solve the problem. I didn't send them in nor did I try any suggestions mentioned here.. as I didn't know back then. One of my 8500 was replaced by Bestbuy Product Replacement Program... but the new unit eventually started to have the same problem... then it was stolen out of my car. Then I had another 8500 with with basically the same problem... also stolen later.

    When I got a 8500 X50 the problem simply didn't exist and worked like god sent perfect (except w/o GPS functions etc of 9500ix.)

    I don't have any false laser problem so far with my new 9500ix either (3 months)... but I don't quite trust these things as I'm keeping my good 8500 X50 just in case my 9500ix starts doing the same kinda thing. Seeing from this thread, it seems possible to be plagued by the same problem again... yikes...
