Mi Bill Posted January 26 Share Posted January 26 We have a 2009 Dynasty Regal IV, and I have electrical issues. My Kenwood cameras are not working. The backup, right and left directional and interion. The monitor in the bedroom is also without power. I don’t seem to have power to them, my Kenwood good time radio, or my CB. I have checked the fuses in the front run bay with no joy. Any suggestions would be helpful. We plan to leave MI for FL on Sunday, and I would feel better with the cameras. Thank you.

Dr4Film Posted January 26 Share Posted January 26 Have you downloaded your wiring diagrams from this site? If not, do so, then look them over carefully for a possible solution. Link to comment Share on other sites More sharing options...
Mi Bill Posted January 27 Author Share Posted January 27 Yes. Still not able to locate the issue. I replaced the fuses even though they were not bad. Thanks for the thought. Bill Link to comment Share on other sites More sharing options...

Bill Feeley 586-610-8692 Please confirm that the LED called VCF SW-HSE on the large circuit board in the FRB is ON. If not, please be sure both battery master switches are turned on and if they are, with the ignition switch ON, post a picture of the small PCB in the RRB (Rear Run Bay). I want to see which led lights are ON. Link to comment Share on other sites More sharing options...
Mi Bill Posted January 27 Author Share Posted January 27 Frank, There was no LED on at VCF-SW-HSE. Both battery master switches are in the on position. these are the pictures of the LED's on the small board in the RRB. I included a picture of the two boards. Thank you.

Frank McElroy Posted January 27 Share Posted January 27 Have you bypassed the salesman latching battery disconnect solenoid in the RRB? If you did, did you move the feed wire and fuse over to the hot side? If not check the fuse on top of the battery disconnect solenoid. Also, check for 12 volts on lug #10 on PCB in FRB. If you have 12 volts replace relay VCFH. Link to comment Share on other sites More sharing options...
Mi Bill Posted January 27 Author Share Posted January 27 I haven't bypassed the salesman switch. I will go out and check the rest of your message. Thank you. Bill Frank, I went out and could not find LUG#10 I found the relay VCFH. I also found out that none of the switches with the salesman switch, step light, handle light, porch light et al have power. Here are pictures of the FRB with VCFH Thank you. Bill Link to comment Share on other sites More sharing options...
Mi Bill Posted January 27 Author Share Posted January 27 Frank, I am not sure what you are referring to about the fuse on top of the battery disconnect. Thank you. Bill Link to comment Share on other sites More sharing options...
Frank McElroy Posted January 27 Share Posted January 27 I circled lug #10. Look at the latching relay to the right of the small PCB. There is a fuse on top of it. Cycle your salesman switch. Hold about 5 seconds to turn it off. One second to turn it on. Do you have coach interior lights? Watch this video. You can cycle the battery cutoff latching solenoid from the RRB.

Mi Bill Posted January 27 Author Share Posted January 27 Frank, None of the ceiling light switches seem to have any power. I'm sorry I don't know what the "latching relay" is. I'm not sure what "small PCB" you're referring to. I will go out and check for power at the lug#10. Thank you. Bill Frank, There is 12v at lug#10. I can't get a new relay until tomorrow when the stores open. I will go out and try cycling the item in the video. Thank you. Bill Link to comment Share on other sites More sharing options...
Mi Bill Posted January 27 Author Share Posted January 27 Frank, I followed the video. I heard a click. Both batt on and off lit up. Thank you. Bill Link to comment Share on other sites More sharing options...
Frank McElroy Posted January 27 Share Posted January 27 Great talking on the phone last night. A lot easier than back and forth posting. Based on our discussions, since you have power to lug #10 and since the house Intellitec lighting system works, the latching relay and the fuse on top of it feeding power to lug #10 in the FRB are all working. However, since both top LEDs light at the same time when pressing the battery disconnect button, the small PCB powering the latching relay is defective. I'm starting to see a lot of those board failures on 09 Dynasty and Sigs. If you can't find a replacement from a salvage yard, contact me offline - I can repair them. Because you have power to lug #10, the likely reason why your dash switches and other dash functions aren't working a failed relay VCFH. But first, if you haven't already done so, reboot the Kongsberg CCM system by unplugging from shore power, shutting off solar and then disconnecting both house and chassis battery banks. Be sure all LED lights in the FRB are out before reconnecting the batteries. After powering up the coach, hold the dash switch dimmer + rocker switch to display all rocker switch labels. Hopefully all the dash switch modules do light up. Link to comment Share on other sites More sharing options...
Frank McElroy Posted January 27 Share Posted January 27 If you find that none of your dash switches work, also check fuse VCA-5 on the FRB large circuit board. Link to comment Share on other sites More sharing options...
Mi Bill Posted January 27 Author Share Posted January 27 FYI Here is a follow-up for all following the thread about my monitors, radio, etc., not working. I want to thank Frank for his knowledge, patience, and diagnostic skills in solving my issue. In addition to the posts yesterday and this morning, Frank called me and walked me through many steps to determine that the latching relay in the rear run bay was working correctly. These steps included the video posted last night and educating me on the different parts. Based on the testing results, Frank determined that the issue was not in the rear run bay but rather a relay on the circuit board in the front run bay. This relay was VCFH. I found a new relay installed, and all of my initial issues disappeared. However, my entry steps stopped working between last night and this morning. Frank had me reboot the CCM by totally powering down the coach. He also had me press the dimmer + switch to ensure that the lights on the dashboard switch modules were all working, which they were. Frank had me check the 30-amp step control or fuse in the front run bay CCM module, F 13. It was getting 12 V. Also try and I could not open the steps by pulling on them while opening the door simultaneously. Frank then suggested checking the controller under the step for power and ground. While looking at the stairs under the coach, I noticed one of the wires going to the magnetic door sensor was not connected. I considered that was the issue. After taking the wires apart, stripping, and reconnecting all of the wires, the stairs opened, extended, and retracted as they should. Thanks, John! Without Franks's help, I would not have been able to get such positive results. This forum and its considerate members are an excellent resource.
