  1. Solution. First, the headlight switch was replaced to fix the panel lights and gauges not working correctly. Headlights were replaced years ago but never driving at night, was not noticed if they were cycling. The lights were always dim. After replacing the switch we decided to tackle the dim head lights. Voltage measurements showed 10 volts to lights, and after a period they would start cycling. We replaced the light circuit with a Amazon relay kit, splicing it into the circuit and using the wires from the switch to turn on the relays. This provided peak voltage to lights and eliminated the cycling. Thanks for all the ideas. I am very fortunate to have a great friend, Myron, that knows a lot about these RVs. He tackled this project and did a great job of diagnostics and installation. Without his help, I would not have tackled the project. The idea of re-engineering an electrical design is best left to the experts.
  2. That is what it is acting like. I changed to halogen and the additional draw may be causing the issue. However, both lights are in sync which would indicate a single circuit breaker and there is nothing in the front bay labeled headlights other than a 25 amp fuse. The wiring diagrams do not show anything like that either. Installed a new switch, not a fun job, will continue looking today.
  3. Our 2000 Diplomat cycles the headlights off and on when the switch is turned on. Is there a circuit breaker for the lights and where is it located? The dash and parking lights remain on. Wiggling the switch has no affect.
  4. It has been called the lift pump. It comes on briefly each time you turn the key on, to build fuel pressure.
  5. UPDATE.............First, I want to thank all of you for the support. We have enjoyed our Diplomat for 15 years and this is the first major issue we have had and we have 128,000 miles on it. Things do wear out, ask my doctor. Anyway, first issue, Cummins needs to know the engine serial number in order to identify the part, I spent 45 minutes on the phone with support but was not able to read number. They suggested I get a shop to identify the serial number by reading the onboard computer. I also contacted www.monacocoach.com and gave then the Vin number, They were able to provide the engine serial number. I contacted a local shop Cummins recommended, just a mile from my location, and they were able to verify serial number, checked the leak, and ordered the parts, The parts arrive latter this week and will be installed by them. As everyone knows, inflation is affecting everything and diesel parts and good mechanics are no exception. Five hours of labor and $500 in parts is not cheap, but considering the service, I am dancing. Thanks again for all the help. I was not able to locate the three bolts on the top of the pump but after all these years of good service, replacement was a logical step and a big relief.
  6. Need a little help. Pulled into Florida and noticed fuel leaking, when engine running, from I think the lift pump. I have contacted local Cummins shop and took pictures, they need a part number. Does anyone have this information? I see many have changed out to a FASS system but I am needing a quick fix and will address that latter.
  7. LP service dealer looked at set up. He explained there was a check valved inside the tank that prevented the hose to be under constant pressure. I went to three different hose companies but none of them had LP 1/2 inch hose, the largest they carried was 3/8. Finally found a place that had correct hose and they made one with correct fittings. $100 hose and 15 minutes of installation and we are good to go. Thanks for all the help.
  8. Maybe the tank they had would not accommodate a fill fitting or maybe it is over engineered. Propane dealer looked at it and walk me through the repair, they could not do it. Seems simple, remove the hose, have a new hose made, install using original fittings. Will tackle project tomorrow while my diesel shop replaces the emergency brake valve. Cold weather is not good for RV's. I promised the Diplomat, if nothing else goes wrong, we will put it in warmer climates, my bones like that idea too.
  9. It is 32 degrees in Kansas and went to fill the propane tank on our 2000 Diplomat. The hose that goes from the filler connector to the tank was leaking and could not fill tank. Have about half a tank of propane and it is not leaking, appears it leaks only when attempting to fill. I suspect the filler hose has a check valve that may be frozen. Anyone have experience with this condition? Is this a special order hose and fittings?
  10. Has the furnace ever worked, with the AC heat strips?
  11. Yes, we were running AC. I suspect the wires were loose in the switch, at lease they were when we pulled it out, but everything inside was fried so hard to tell. I agree with you, annually pull the box cover and torque the screws. Make sure no current is present , no generator, not plugged into shore power, and just to be safe, both battery sets turned off. Not an expert but a quick learner. One time, I found loose connections in a fifth wheel parked next to us. Found his transfer switch. tapped it, and power came on. Not a good sign.
  12. Please be very cautious this weekend. I am not an expert and do not understand some of things recommended or the things you have done to get things going, but I have had a transfer switch melt down and take out two TVs, microwave, Norcold, and inverter. Luckily, my computer equipment was plugged into surge protector cord and it only fried the cord. But, when I say the transfer switch melted down, it really did. This happened in the middle of the night and we are very blessed that there was no fire. The transfer switch, on our 2000 Diplomat, is located right under the bedroom.
  13. I purchased the scan gauge seven years ago. It is simple to install, just plug it in and select monitoring. While it only displays four items, the menu has many items you can monitor. For me, simple is best, being a pilot I need to be monitoring outside and not get too distracted with screen data. For me, simple is best when driving.
