I installed the Audiovox ccs-100 on my D, following Ryan's great site and the included instructions. Tried it out, didn't work. Checked everything according to the manual, all voltages present at the correct pins, connection to coil Ohm-ed out, vacuum connected to the large hose that enters the left pontoon, air gap at the pickut 1/8", but I didn't get the flashes of the LED in the control unit when each signal was tried. So I called audiovox and they said it was probably bad. Called Brand's Place for a return and ordered another. Found out from the manager there that several units of the ccs-100 have been returned as defective recently. I ordered another anyway and installed it on my D. This time, I see very faint flashes of the LED, but still no operation. The serial number of the new unit is far removed from that of the first one I tried, so I had high hopes that if there were a series of bad units, I would now have a good one. Ryan, you mentioned in earlier posts when you were trying to get your unit working that you had insufficient vacuum. What were you readings and how did you fix it? I am tied in at the location you suggested on your site. I am about to order the Dakota Digital electronic cruise control that uses the spedometer cable to control the speed and requires no vacuum. Has anyone on the list used one of these successfully? It is $250 vs $80 for the Audiovox, but I really wanted to get this working before the LOOONG drive to Houston Thursday. Any help will be greatly appreciated.
