Magnetic Ground Sensors

I have just recently started driving my rebuilt '87 CJ7 with a 4inch lift and 33's on the road. I'm having a problem with magnetic sensors at the gates to apt. complexes, fast food drive restraunts and especially at red lights. I had to drive through about 3 red lights this weekend because they did not know I was there. Have any of yall had this problem or would know what to do to fix it?

do you have a fiberglass body or front end on it? I could see that as being a problem. Just thought I'd throw it out there.

No it's not fiberglass. I really dont see why it's not working. I'm not THAT high off the ground.

Do we know for sure that the sensors are magnetic? Could they be pressure sensitive? If so, maybe the larger and softer footprint of the tire, combined with the height........maybe a call to the Austin public works dept.

They're not magnetic, they are activated by weight. Except for the ones at the drive thru's. They are close position motion sensors. They are probably going under your frame. McDonalds is still like that around here, but most other drive thrus have integrated two sensors now for higher vehicles.

I've never heard that magnetic thing, although I often see people flashing their bright lights at a stop light thinking that will make them change

At the camp I worked at, the gates were magnetic. On one side you needed a code to get in, on the other the truck just had to get close and the gate would open. Whenever we walked past it with something big and metalic like a 2 wheeled cart it would open. Stop lights on the other hand are activated by weight.
