RE: Battery rearrangement

The only reason to consider it is so that I have more options on the house battery side. The battery box under the step it very tight while the rear compartment is much larger. I'll probably just leave it alone and see how it all works out - we have only had it a short time. And as to the engineers have a good reason - I doubt that very much.....I believe this is only for the diesel as it requires 2 batteries and there is no place to put them under the hood. I suspect they did not make enough of them to really spend a lot on design.

RE: Battery rearrangement

All cables attaching to the solenoid appear to be the same gauge. There is a fuse. It just looks easy to do as all wires are accessable under the step beside the house batteries, There are 2 cables coming in - one from each battery set - so it would be easy to switch around. I would need to switch the batteries so that the deep cycle ones are in the new location. The starting batteries may not fit in the step battery box so it may not work.....

Battery rearrangement

We have a 2007 Coachmen Concord with the Ford 6.0l diesel motor. The 2 house batteries are located under the entry step which I understand is normal practice. The 2 starting batteries are located in a compartment at the back of the motorhome. This seems backwards to me but that is the way it is wired. I assume this was because there was no other place to put the starting batteries. I would like to switch this around. It appears that I can just rearrange the cables at the battery 'combiner' solenoid. Has anyone tried this? Thoughts? Thanks.

RE: Mobile internet in Mexico

Thanks for the feedback. We are planning on a 3 month tour next January that basically goes through most of Mexico. The problem with these plans is that you need to be very careful how you use them as you can burn through the high speed data very quickly. I have the hotspot feeding a router that can have several connections. As you say the Telcel plans are not that expensive and could be renewed as required. It's a ways to go yet but Telcel seems to be the way to go.

Mobile internet in Mexico

I am looking to have an unlimited hotspot data plan in Mexico (for 3 months). These plans are very common in the US and becoming more common in Canada. Most of them have a certain amount of high speed data and then unlimited low speed. This would fit my needs perfectly as low speed data would be fine for my application. I know that US carriers offer US/CAN/MEX plans now that look to do this but I have no idea if they really do - lots of fine print about use as a hotspot. I would also like to know if anyone knows of any lower cost options. At home in Canada I use a $15/month plan with unlimited low (quite low) speed hotspot data and it generally works fine. Thanks.

Cedar Creek Cottage CRS40 Window

We have a 2014 CRS40 sitting in Mission Tx with a broken window. It is one of the large windows in the living room slide. It was broken by the landscaper and they have agreed to fix it but are telling us that the window is no longer available. We are at home in Canada for the winter and communication through the park office has been an issue. Fortunately, we have double pane windows so there are no weather related issues. Does anyone know where we can source a window in the south TX area.

RE: House/chassis battery issue

As I understand it the problem is not that unusual and is likely due to leaks in the high pressure fuel system. I don't think there is any danger to the engine just an unusual long crank when cold as it gets the fuel pressure high enough that the ECU allows it to start. It is a late '07 motor and has 124k km so about 77k miles on it and runs well otherwise. Faster cranking speeds (from fully charged batteries) do make a difference - thus the idea of keeping the batteries charged. Because I have a solar system on it I can use it to always keep the batteries charged but needed a way to include the chassis batteries which the new interconnect takes care of...

RE: House/chassis battery issue

No. I have added a separate relay. I do normally use the dash emerg start tor cold starts as it provides a better cracking rpm that reduces start time on the 6.0 diesel. This issue is related only to my motor and would not apply to most. I am hoping that the ability to keep both sets of batteries charged helps with winter storage.

RE: House/chassis battery issue

To complete the picture I have now added my own version of a trik-l-start - essentially my own interconnect relay that I can control with my on-board data system. Once the house batteries are charged (in float) I connect the batteries and let the solar charge the chassis batteries. Exact logic to be determined but it seems to work fine. I plan to use this approach to maintain both sets of batteries over the winter although the effect of heavy snow may need to be considered.

RE: MPPT Controllers

With respect to your original question on data display I would like to offer an alternative approach. Rather than purchase an off the shelf solution - usually quite expensive - I suggest you just make your own! The basics - say a shunt on the batteries and a MODBUS data connection into your solar charge controller are available at very low cost (<$50) and offer essentially unlimited capabilities all with no cost tools. I'm not saying it will be easy but it will be cheap and you will end up really knowing what is going on with your system. If you are at all technically inclined I'm sure it is achievable. Something to consider...

RE: House/chassis battery issue

Problem has been resolved. It seems that the dash battery interconnect button must be pressed with the key off. I was pressing it with the key on just before turning to start! My solar system keeps the house batteries fully charged so with the button I get good cranking speed and a start in maybe 2-3 seconds rather than 5-6 seconds. I will leave as is for now but will continue to look for the current leaks. Thanks to all for the discussion.

RE: House/chassis battery issue

Well I think the Trik-L-Start is a DC-DC trickle And somewhat related to the last comment it seems that the house batteries are under the entry step (2007 Coachmen Concord M275) while the chassis batteries are further back in a compartment. I thought it should be the other way around and actually took the unit back to the dealer to confirm but was told that it was correct. It seemed odd to me. Can anyone confirm that this is correct?

RE: House/chassis battery issue

Batteries are new. I will continue to monitor to see if there is something going on with a unknown current draw. (several modifications have been made by previous owners - alarm/remote start/... - so it is difficult to know exactly what is going on) The use of a separate battery charger would require the inverter and seem more complex than just using the Trik-L-Start. It appears to have all the smarts to effectively replace the charger with no user intervention and would be an excellent long term solution. Maybe I'm missing something. Thanks to all for the discussion.

RE: House/chassis battery issue

The problem I am dealing concerns the cracking speed of the motor. This is a 6L Ford diesel and it needs to developed sufficient pressure before it lets the engine start. THe faster the crank speed the faster the start. Even using the battery interconnect button does not help much. Of course, it can be fixed but as a work around it seems that having a fully charged battery does make a difference. There could well be a problem with some sort of unknown current draw - the battery was at 11.7V after 10 days or so. This 2007 unit is new to me. Also I should add that 120ac is not available where it is stored. It has 340 watts of solar.

RE: House/chassis battery issue

This is essentially what I had in mind by using the battery interconnect solenoid. I think the Trik-L-Start looks like a good install and forget solution....

RE: House/chassis battery issue

Anyone know of a source for the Trik-L-Start in Canada???
ramsaymike 08/18/20 04:35am Tech Issues
RE: House/chassis battery issue

Thanks for the ideas. I like the look of the Trik-L-Start. I should be able to simply install it across the interconnect solenoid - I think. Sounds ideal to me as I will always have active solar charging every day and can just let it keep the starting batteries charged.

House/chassis battery issue

I have a 2007 Coachmen Concord DS275 and discovered that the only way to charge the chassis batteries is by the alternator. Shore power charges house batteries only. This is a real issue for me as the engine cracking speed is critical in starting the 6L Ford diesel. I also have a solar system but it too is house only. I would like to be able to use the solar charging as needed to keep the chassis batteries fully charged. The battery interconnect solenoid would seem to be what I need to use but when I activate it (apply 12v) the headlights turn on which greatly reduces the charging efficiency. Any ideas appreciated.

RE: Battery interconnect logic

Not looking for more equipment - just trying to make the best use of what I already have...and no DC fridge.

RE: Battery interconnect logic

Thanks for the replies and input. My real goal is to try to make maximum use of the money I spent on the solar system. The fridge is just something that seems doable (vs hot water for instance). So if I'm driving along and by - say - 11 the house batteries are fully charged the power available from the solar system has no place to go. My fridge uses 330 watts while running on AC - certainly more than I can produce on solar at any time. My idea was to use an inverter to run the fridge for a time based on keeping the batteries at a suitable SOC to get through the night if no hookup is available and the weather cooperates - no AC required. I can just turn the ac power off to the fridge to have it switch to propane as needed. Doubtless, this is not a very practical application but I enjoy such things. I would prefer to keep the alternator out of the equation as no matter how much it still requires fuel to work. (I'm into home automation and am instrumenting the unit to monitor/control electrical flows and device states where practical) Is there something better to do with excess solar? Other ideas?
