That "CLOSES" the Big Boy or makes the circuit. The Diesel2 checks for voltage on BOTH batteries and there is some magic and if the "charging" or Bi-Directional conditions are correct.then the BIRD Diesel2 sends a signal to the Big Boy. The version of the Big Boy that Monaco used in 2009 was a 12VDC 200 Amp relay. as well as MEMORY (there MAY or probably WAS a Latching Version of the Big Boy.this control is not, I think, designed to be used with that one) There was an original BIRD (relay controller) that was NOT the Diesel 2. Larry Laursen is actually the MOST knowledgeable person on the history of how Monaco tried to cobble up Bi-Directional capability.starting way back with the Lambert and some Trombetta variations. The Diesel2 was designed to be used with the "latest" version of the Intellitec Big Boy. The Good Dr (Richard Smith), I think, has a similar setup.įROM the top. For the RECORD.The Intelltec Tech Support Crew, who has spoken to the Gathering a few times, says that the older MH's were overly complicated. You need someone that is handy with a VOM and you need to chase the new wires. Never, EVER (even me) trust anyone's "rewiring" or a Tech's. My experience might not help.but I can tell you that I have the SAME Diesel2 Relay or controller. The pdf RJ Chapman posted with troubleshooting steps should help figure things out. The replaced relay in the photos is in the front electrical bay. I guess this is what controls the Trombetta or Big Boy relay. An earlier owner of my 2005 HR Scepter apparently replaced whatever Monaco had installed (see photo with 3 clipped wires from the Isolator Relay Delay) for an Isolator Delay controller and replaced it with an Intellitec bi-directional isolator delay relay 00-00839-000. I still don't understand what my coach is doing (see earlier post - same topic), but I thought these photos might help others. Let me know how you resolve this, as it might apply to me, too.Ġ6 Dip wiring -dip_chassis_12v.pdf 2005 Camelot wiring diagrams.pdf I have attached a one page electrical diagram for a Diplomat, and a many page electrical document for a 2005 HR Scepter, of which many of the diagrams are for more that just the Scepter. Some time ago I was diddling with the Trombetta relay and found it would pull in a few minutes AFTER I started the coach engine, and that seems consistent with the system making sure the chassis batteries are fully charged before switching to charging the coach batteries. So maybe my system is working OK but I don't know it. ) Once I arrive at my destination, my monitor says the coach batteries are practicality fully charged, or are at 100%, which shouldn't be so if they have been discharging all day. Then the discharge is more like 4 to 6 amps PLUS 80% of what my solar panels show they are putting out (which all seems backward. I can drive all day and the Alladin monitor show a 4 or 6 amp discharge all day from my coach batteries unless my solar panels are charging, too. I have similar issues, but I am not sure what is happening. Getting ready to get on the road for the summer soon and need to get this repaired. Everything is normal except for the house battery charging.Īnyone know where I can obtain a wiring diagram of my 06 Windsor? If I had that, I could locate the problem.Īnyone know a repair facility anywhere in the country that I could call to find the answer? What I need to know is, where does the power source come from that activates the relay when the engine is running? The alternator was just rebuilt and is outputting normally. In other words, the relay should close when either the Boost switch is pressed or automatically when the engine is running. The problem is, when the engine is running, the relay should be receiving another power source that closes the relay like the "Batt Boost" switch does. It closes when the "Batt Boost" switch on the dash is pressed when the engine is running and when it is not, as it was designed. I've done as much trouble shooting as possible and have determined that the Trombetta/Bear paralleling relay is not defective. My house batteries do not charge when the engine is running.
