  1. Not sure what I was looking at earlier that said 70A. All the references I'm finding now say the LR9806 latching relay is rated for 110A. So I'm feeling pretty good about having all the house loads on a single relay. Cheers, Walter
  2. Thanks guys. Jamie: that's exactly the situation I have now. I have a continuous solenoid that draws power when the salesman switch is on (which is almost all the time). I'm looking to eliminate the parasitic draw. Joe, I've also got a spare latching relay. My original plan was to replace the continuous relay with a 2nd latching relay. But the area around the continuous relay is very tight and the latching relay is a lot bigger than the continuous, so installing the 2nd latching relay looks to be a big hassle. I was also concerned about potential inconvenience and confusion that might result if the two latching relays somehow out of sync. I'll go ahead and try it out. Other than the inverter (which doesn't go through these relays) I really don't think I'll see anywhere near 70A. I just turned on ALL of the house&storage bay lights, and with the water pump running came up with about 40A. The aqua hot and all three furnace zones add about another 15A. So I really can't see my house loads ever going beyond about 55A. I'll try it out and report back. Walter
  3. Hi All, I've added solar for boondocking and trying to get my baseline electric utilization under control. One obvious energy waster is the continuous relay attached to the salesman switch. On my rig, the salesman switch is connected to a LR9806 latching relay, which cascades to an automotive-style continuous relay. These two relays feed different domestic load panels. The continuous relay uses 750mA, and I'd like to eliminate that 18Ah daily load. I realize that the easiest way to eliminate this load would be to bypass the salesman switch altogether and just jumper across the relays. But I kind of like the salesman switch and I do use it occasionally. The latching relay is rated for 70A. I've already changed all FORTY of the house halogen pucks to LED, so I'm not sure I need two 70A relays for house loads. I'm thinking about eliminating the continuous relay and combining both house load circuits onto the one latching relay. Just looking around the rig, I'm not seeing more than about 50A worth of house loads. Am I missing something? Anything wrong with this plan? Thanks, Walter
  4. Ok, got it done... Like so many such projects it didn't quite go according to plan... I tried pushing a fish tape in from below, and it never got to the point where it felt like it was striking the outside wall of the slide-out. So I left it in place and dropped a cheap chinese borescope down from the top. Couldn't see the end of the fish tape, and it looked like black foam around the cables making the turn at the bottom. So I'm pretty sure they foam'd it like all the other wiring penetrations. Side note... There look to be some unused wires in the bundle coming up through the floor. The only low voltage circuits in the slide-out overhead are three lights. But the bundle going overhead in the slideout includes 4 12v wires, one ground wire, an un-terminated phone cable and what appear to be two speaker cables. The bundle coming up through the floor also included an unused white 12 ga ground wire that was not terminated. It looks like maybe they initially ran a 12ga ground all the way up into the slideout overhead, and then later pulled an 8 ga ground wire into the cabinet, added a ground bar on the floor and then cut the 12 ga ground wire to terminate one side of it in the ground bar. So I used the orphan ground wire to pull a string back down through the bundle and then used the string to pull cat5. Now I can put my solar controller on the network! Cheers, Walter
  5. Thanks. Mine is different though. I tracked it down. There's no actual fuse. The 4/0 positive cable runs from the battery switch to the high current run bay in the engine compartment. From the battery boost solenoid, it goes through two parallel 150A circuit breakers. And from the circuit breakers to the inverter (see attachment). So there's no fuse protection between the batteries and the boost solenoid, but the inverter cables are protected by circuit breakers.
  6. Hi all, The 2003 Dynasty wiring diagrams show a 300A fuse in the house battery cable after the battery switch (see attachment). But I'm looking up into the cavity behind my battery box and I'm not seeing a fuse there. The positive battery cable runs from the batteries, through a bulkhead post, up to the house battery switch and then up over the frame rail and out of sight. Do any of y'all know if I should have a 300A fuse somewhere? Thanks Walter
  7. Thanks. That gives me an idea. Maybe feed a magnet through from the bottom on a fish tape, and drop a line with a small steel weight down from the top.
  8. Thanks guys. I think I'll try both of those approaches.
  9. Yeah, I was hoping I could use the old phone cord to pull a wire back through, but I opened the part of the bundle that's visible and it's pretty tightly wrapped with tape about every 6".... I'm starting to think this may be more trouble than it's worth. The fish tape is going to be tough. The wire port goes straight down about 10" to the bottom of the slide and turns back 90 deg into the chassis tube. I might see if I can disconnect the tube where it connects to the inside of the slideout. If I can disconnect and retract the sliding tube it may get a lot easier... Thanks, Walter
  10. Here's a video showing the information available from the MPPT-60: Cheers, Walter
  11. Hi all, I'd like to pull a network cable into my living/dinette slide-out. I can see the end of the telescoping conduit inside the frame rail, and I've dug into the cabinet under the dinette and can see where the slideout wiring enters under the cabinet. What's involved with fishing a wire through this tube? I'm not seeing an easy way to push a fish tape in the tube and turn the corner up into the cabinet. Thanks Walter
  12. Thanks. We're on the same page. My brackets attach differently than AM solar (mine attach to the bottom instead of the ends), but similar functionality. In addition to the extenders, I was thinking that I should have installed rivnuts on the brackets instead of using wingnuts on the back side of the knob. My roof layout is a little different. I've got 2 panels on the certerline and the rest will be on along the road side. So all of my shading problems are coming from the same direction.. Cheers, Walter
  13. Thanks Glenn. I’ll experiment with extensions. And I’m kicking myself for not setting rivnuts in the brackets. Still thinking about it, but half of the panels are stuck down at this point, so re-drilling and adding rivnuts will be a pain! Cheers Walter
  14. Ok, here's what I wound up with. I used the Renology extrusions on the panels and made some 3" long brackets from 1/16" 2x2 AL angle for mounting to the roof with VHB 4950 tape. This makes one $30 Renology kit work for 2 panels, plus my home-made attachment brackets and some additional hardware. VHB 4950 is what AM Solar uses. I was concerned that a thick 1/8" extrusion would have no flex and might be too stiff to work with the VHB 4950 tape as the roof surface flexes. VHB 4950 tape uses 3M's 'firm' type foam and is quite hard, so both surfaces need to be very closely matched. 1/16" AL seems to be working well. The roof flexes quite a bit and the brackets also allow some flex. If I were starting over, I might use VHB 4941 tape which has 'conformable' foam. It's not as strong as the 4950, but the softer foam might be easier to work with (and with 6sq-in per bracket, tape strength shouldn't be much of a factor...). So, now we'll see how they hold up... I've got 2 more panels to mount, combiner box, the new controller and a bunch of wiring... Cheers, Walter
  15. Ok, you guys have me convinced. It's VHB for me. I looked at the AM Solar brackets. Very nice, but they cost $80 per panel... So I got a renology tilt bracket to try out. My plan is to adapt the renology mounts: using two of the extrusions for the back of a panel and then cutting short sections of 2"x2" aluminum angle for the attachment feet. I realize that I will seldom, if ever tilt the panels, but this should be cheap/easy mounting and allow the option of tilting. Cheers, Walter
  16. I was going to attach it, but it's 79MB and too large to attach to the thread. Just uploaded the full wiring diagram document with TOC in the files section: 2003 Dynasty Wiring Diagrams with TOC
  17. Thanks guys. I'm warming up to AM Solar's VHB brackets. I was concerned that the flexing of the roof skin may be a problem for the tape. Maybe that's not the case. Walter
  18. Hi All, I believe a PDF of the 2003 Dynasty Wiring Diagrams has been available in the community files for a long time. That has no table of contents (neither does my original hardcopy), so I have to page all the way through it every time I look for something... So here's a TOC I paid my kid $20 to transcribe. This hasn't been thoroughly checked for errors... Cheers, Walter 2003 Dynasty Wiring TOC.docx
  19. Hi All, I'm getting ready to replace my one original solar panel with four new ones. The roof is a loose fiberglass skin and feels like a thin layer of thin plywood underneath. I'm thinking it would be impractical to find ribs to screw the mounts into. Are the brackets just fastened into the plywood skin and plywood with wood screws? And on panel locations: the original panel is on the center-line just aft of the middle A/C. I'm planning to put one in the same location, and another immediately aft of it. These two shouldn't have much of a shading problem. Then put two more panels on the road-side next to the front and rear A/Cs. My reasoning is that I can probably position the rig to minimize shadows if both panels are shaded the same way. Picture attached. Does this sound like a good approach? Thanks Walter
