Hi everyone!

I have a Power Gear leveling system with a 500675/140-1231 touchpad on a 2004 Damon Challenger 348W.

When I was having problems with the system before, I noticed that the previous owners of my coach had soldered the wires for the touchpad controller straight to the touchpad, (i.e. they had removed the square pin sockets on the wiring harness and the touchpad. I ordered a new touchpad from LCI. The new touchpad has a flat 4 pin connector as opposed to the square connector that the original had, so I ordered a wiring harness adapter for it also. Unfortunately, the wiring on the new harness adapter does not match the colors on my existing harness wires. On my existing harness, the wires are red, black, blue and white and on the harness adapter, the wires are red, black, green and yellow. I tried contacting LCI, but the info that they sent me was for a different touchpad model.

Does anyone have a similar touch pad that they can take a picture of the square connector and post it up for me so that I can wire up my touchpad? Or has anyone changed their touchpad for the newer one with the harness adapter and can tell me which wires match to which?

Thanks!

OK, I found a guy in my campground who has the same touchpad. The wiring is as follows:

red - red
black - black
yellow - white
green - blue

Recently bought a 05 Damon with this same 500675 touch panel leveling system. System was intermittent. Traced to loose plug on back of touch panel. Plug actually fell off while removing the panel. The four pins of rectangular connector are all that remain of the surface mounted connector. The plastic housing that holds the pins and ensures proper orientation of the cable connector is gone. As the connector is perfectly square, I have only a 25% chance of guessing the correct orientation. I definitely DO NOT want to blow this $500 dollar board through experimentation. No manufacturer docs are helpful.

Can anyone out there with this very same touch pad and the original square connector configuration (there are several newer variations) please help me get this back together right the first time. I have attached a couple pics of my situation. The cable connector has four wires: white, red, blue, and black. Also it has a alignment/locking tang that can be used to help me orient the connector as either Up, Right, Down, or Left.

Thanks. Living lopsided til then. Cliff

Hi cliffgi,

If you check the attached picture, the red arrow points to where your ground, (black), wire connects.

I hope this helps.

BTW, if you try soldering the wires directly to the panel, be very careful about how hot your soldering iron gets. I let mine get to hot and the pins came off and I couldn't get them back on! I had to spend $250.00 USD to replace the panel!

Thanks Zog.

Just to be clear, please confirm that your red arrow is pointing to the lower-right pin.? If this be the case, the connector's locking tag will point to the right as circled in my original pic. This would put black on the lower-right pin, blue on the upper-right, red on the upper-left, and white on the lower-left. Is this correct?

thanks, Cliff

Daaaa! I just realized that in my original pic of the circuit board, I mislabeled the left side of the connector as ""Right". Obviously, I meant left is left.

cliffgi · 09-29-2016, 08:06 PM

Left is left and right is right.

Zog. Thanks for the soldering tip.

I had pretty much decided that soldering the board was a bad idea. The runs are very thin. I have decided that the best course is to cut the original harness connector from the harness to make a 6" pigtail. I'll install new connectors to the cut ends. Then I'll then carefully insert the original connector end of the pigtail over the pcb pins (properly aliened) and epoxy in place. After reinstalling the pcb's protective back-plate, I'll install a pigtail strain releaf attaching it to one of the back-plate mounting screws. Finally I'll attach the new pigtail to the wiring harness and secure the touch panel to my RV console.

That should do it.

When all is done, I'll attach a couple pics of the modification to this thread.

Zog. I just ran a continuity test between the circuit board pins to the TIPC6C595 IC chip on the board and discovered that the IC's GND pin, as shown on the chip's datasheet, has continuity to the upper-right circuit board pin, not the lower right as you indicated. Additionally, the upper right pin also has continuity to GND pins of other known chips on the board.

Are you absolutely sure that the the black pin is GND and that it matches up with the lower-right pin? What are you using as a reference?

Not trying to contradict you, but there is reason to question.

cliffgi · 10-09-2016, 03:18 PM

To ALL.

Zog was right. For the original four pin plug on the 500675 touch panel, as viewed from the back of the touch panel (with IDS, Inc. text at bottom), the pin to wiring harness colors are as follows:

Lower-Right pin = black
Lower-Left pin = white
Upper-Left pin = red
Upper-Right pin = blue

Hope this helps someone.
