Yes! Thank you. </div></BLOCKQUOTE>
I had one on my 1994 Vectra with HWH 610 computerized jacks. Get the manual off
http://www.hwhcorp.com/ . The manual will explain how to adjust the sensor positions screws. I never had to adjust mine though. Basically you level the coach and adjust the screws so all the level indicator lights are out. I wouldn't adjust it unless I was having a serious problem.
Quoting the HWH 610 manual below:
MOUNTING AND ADJUSTMENT INSTRUCTIONS
NOTE:
The sensing unit must be mounted to a solid surface and must not be exposed to any heat sources. Toward the middle of the vehicle but outside the frame rails is best. The sensing unit may be mounted between frame rails on pusher vehicles and trailers. The sensing unit may be mounted in a compartment but needs to be protected from stored objects. It is critical that the sensing unit is mounted in the proper position according to the sticker on the sensing unit. (See figure below). The springs should be compressed to approximately 1.25 inches.
The correct method for adjusting the sensor is as follows:
First, level the vehicle by placing a 24" level in the center of the vehicle on the floor. With the vehicle level adjust the sensing unit until all yellow lights are out. This is done by drawing up or backing out the sensing unit screws. If a front light is on, adjust the front screw. If a side light is on adjust the side screw. If a rear light is on adjust the rear screws. One or more screws may have to be adjusted to turn the yellow lights out. After adjustment has been made, pull down on the sensing unit to make sure the unit is bottomed out on the screw heads. Check to make sure all yellow lights are out. If not, readjust. Rock the vehicle and recheck
for yellow lights, readjust if needed.
