Thanks Frank .That switch is for connecting batteries as well as a disconnect. I am going to order the one I mentioned above. It looks like a duplicate of the original cole hersee. The distributer is in the Phillipines. Could be from China but they specialize in race car items so hopefully it will be decent quality. I sent a message to Cole Hersee but no answer yet. The world of automotive electrics has changed . Many companies have been bought out by conglomerates. Often wonder if this is a step backwords.

Amazon.com: Fastronix 300A 1/2" Severe Duty Master Battery Disconnect Switch with Face Plate : Automotive I think this would be a good substitute. I have not checked to see where it was manufactured

Scotty. Thanks for that idea. The switch in the parts list is for selecting 2 different batteries. Cole hersee is now part of littlefuse. I cleaned up the old switch and it has 2 1/2 inch poles and 2 10/32 poles. I can see some of the original part #. It looks like 759. The rest is unreadable. I looked in the catalog but can only find a switch with 3/8 poles. I am assuming that my swirch can handle higher amps. I am still searching. Thanks

I should explain myself better. On an 08 Dynasty with 8 - 6 volt batteries the disconnect switch is mounted to one of the side walls of the front battery bay. There are 2 switches, house and coach. One can access the back of the switches by removing a narrow plate on the wall of the rear battery box. So the guts of the switch are betwen 2 metal walls. With the rear batteries removed you can just barely get in between to undo the cable. Ther are 4 studs.2 are large studs. 3/8 I think. The other 2 are 10/32. The large cables do not have much play. The small wires can be extended if requires. So the replacement should be the same style. I have not yet seen any part # on the switch. Thanks

I will be shopping in Tucson. No Blue Sea. This is not an ordinary 2 pole switch. Lots of Offshore stuff but I want quality. All I need is a part # and I can order online. Thanks

Where can I find a Cole Hersee battery disconnect for my 08 Dynasty. There are 2 large poles and 2 small terminals. Mine are working but I would like to have a spare. Thanks

Thanks Frank. I tried turn signals, horn and a few others and they all work. I just reb uilt my spare Bog Boy and will change that out as well. My new solenoids will be in Tucson in 8 days

The Saga continues. I have a new to me board for the charging setup in the RRB on the way. I removed the old burnt board. Then I temporarily connected together both terminals on the upper small relay. The inverter is charging the batteries and all the interior lights, slides, etc. are working. The bottom relay is working. I went to start the MH. It tuned over but would not start. Found a loose fuse and now it starts. But when I open the FRB all the red lights are on. I know that some normally are red but should almost all the lights be red? A couple of them are amber.

Frank. There was some sirt of shirt andsm oke was coming from the bottom right of the board. I removed it and the board is fine but there is a small black rectangular device that is slightly melted.I checked for continuity and all is fine. Paul whittle is sendimg me a board and I k now a company here in Mexico that repairs electronicboards. I thought a schematic might help. I really would like to do away withe salesman switch and and that board. But for now I am going to order a new relay and install a board. I am not as sharp as I used to be.

Is there a schematic available for that small board. I want to take it to an industrial electronic repair company. They are supposed to be sharp! A schemaitic might help. Thanks

I echo all of the above comments. Frank ( and others as well) are way better than even the good old boys that used to be tech support at Monaco!!! If this forum and the great members did not exist I might have sold my unit!!

Thanks again

Thanks Frank. So I should reconnect the wires on the lower relay and bypass the upper relay by moving the wire from the right side to the left. In one of my photos there is a heavy wire and a small purple wire going to the bottom copper bar. Is that correct. B When I bypassed the bottom relay could that have caused a short?? I hope the board will still work

I think I made a mistake. I hooked up everything and I still had no lights or12 volts in the coach. I pushed the tiny battery disconnect and the light is not on. Tried 3 times. Then I smelled the dreaded electrical burning. I turnedoff the 2 battery switches and removed the grounds. I will add another photo of the board The bottom right of the board has a small black rectangular item. It isstill intact. I have not checked to see if there is continuity to the board. I gave my other board to a friend so it could be repaired. He is in Yuma and could send it to Tucson. But I am concerned that there is something wrong.

Thanks Frank.

Thanks Frank. So if I understand the 12 volt allen head bus bar at the bottom is the 12 volt feed to the items listed on the bottom of your diagram. I am sure the relay is bad It does not latch. If I apply 12 volts to the right side terminal the lights all work. I think I will bypass it for now. I am in Mexico and doubt I could find that relay. I am surprised as I have never used it until last week. Thanks for your help!!!

Must be a full moon with all the salesman switch problems. I followed Frank's instructions. I cycled the small switch on the board. The green light comes on for battery disconnect but goes out when you let go of the button. The iso relay light is on and shuts off when the batteries are charged No 12 volts on the right side of the upper relay. I then applied 12 volts to the the right side of the relay. All the lights, etc. work. It is not very easy to just run a cable from one side of Sorry I did not finish . Not enough room to attach a cable from one side of the relay to the other. But there is a copper that runs from the allen head contact bar at the bottom. Are those wires attached to the contact strip the feeds to the circuit board? I could pick up 12 volts from the bottom contact bar and attach to the relay. Or is one of those wires on the bottom contact a feed from the house battery disconnect in the battery compartment.? I have not tested that house battery disconnect yet as I have to remove 4 batteries. Hope this is clear.

Hi Frank. My coach is just a house multiplex. Intellitec.

We have been busy for the last week and I could not work on the Dynasty. It has been in my shop all this time. We were gone for 4 days so I used the saleman switch and for the first time. and also turned off the battery disconnects. Returned today and turned all the switches back on. Everything around the dash lights up . But none of the light switches in the rest of the coach work. No slides and no lights. I immediately thought of Tom's comments on the salesman solenoid. I think all of this is related to my blinking lights(As Tom stated!!). I will open up the RRB tomorrow and see what I can find. Where is that solenoid.? It cannot be the 2 on either side of the Big Boy. While I am in there will make sure all terminals are tight

Lately I am getting frequent regens. . This happened once before. Cummins discovered that somehow the software was not letting the regen to continue. They corrected the issue with the ECM and did 2 forced regens. After this all was good. However that was about 7 years ago. I thought that with these code reader devices I could check for a hidden code and try cleaning the DPF. The alternative would be to take the MH to Cummins ar a good shop and see what they can find.

Has anyone here tried one of the many scan tools that will work on an ISL. I see units that will do a forced regen for just over $200. I need that capability. Thanks

I will be 80 this late spring. I still do some work on the rig. Nothing that involves heavy lifting. The minute you say "I am too old" will lead to the end. Sitting around doing nothing is a bad idea. .

The recently released tst 770 comes with a repeater. I thought the repeater had to be mounted closer to the rear. Not so. This system allows you to mount it anywhere out of the elements. I had one of the original pressure pro units Same as the Doran. It was a bad desig. Lots of false alarms. Then bought the old style TST. It was no better. I saw the new TST at Q. Rechargable battery. Huge color screen. Takes normal batteries. But expensive. I am wating to hear from new users.

Does it have a salvage title? I wonder why they are selling it without further info? Somone could pay big bucks and be in for a big surprise.

Thanks Tom. Where are those 2 solenoids? In the rrb? Ido have the electrical diagrams but if it is complicated my rain cannot handle a good diagnosis. I was going to do the common things first. Connections in the closet Maybe check all the grounds. The only lights in the closets are green. Don't have time to fool around for a few days. Will post any outcomes Thanks
