hello, my 84 Fleetwood level ride is acting up. It will charge the first time properly, charge a second time when weight is put in (stops when weight is removed), will charge a third time properly and then that's it. It will not charge the air shocks again until the key is switched off then on no matter what kind of weight is in the car. Noticed on the wiring diagram that there is a fused wire marked "reset". just goes from fuse to sensor. I can use the test wire to run the system without any issues, and I have already tried another good sensor. Any ideas would be appreciated. thanks.
