Nuisance Loads & Coolant Fan Hydraulics

Yahoo Message Number: 6462
Maybe Nuisance Loads would be a better term. I'm surprised that CC does not address the issue in there owner's manuals. Of which I've read many times and still see items I've overlooked on previous readings. These CC Coaches are very complex devices!! Just this weekend I was gazing into my Engine compartment with amazement, and noticed a label on top of a hydraulic reservior that mentioned changing a Filter every 6,000 miles. So now it is research time in the manuals on the official prodedure for this. I'm not sure if it pertains to Cummins Engine systems or is a CC add-on.
Cheers!! (Nice meeting and having Dinner with David and Karen at recent CC Rally. Being a 1st timers I was Impressed at CC's ability to get so much service work done in the short time allowed) Lee ('01 Intrigue #11219, with 350 ISC and '62 Morris Minor Towed(/in Portland for the next 15 months, then Most-Timing It!!!)

Sorry Guys, couldn't resist the my comment.

Hi Lee, A pity we didn't have a little more time together at the rally, I would have enjoyed seeing your Morris Minor.
One of my first visits to the continent of Europe was with two buddies in a very used 195X MM estate car (wooden sides). Not my car. It held everything we needed for three weeks camping. My first motor home experience?
For some reason the prior owner had installed two air horns under the hood and they were extremely powerful. When traversing the mountain roads in France and Northern Italy we would use this horn frequently when approaching blind curves.
When we rounded the curve we would frequently find oncoming traffic stopped and huddled as close to the roadside as they could get! They were expecting some mammoth oncoming truck to appear but it was only us in the little MM. We had a great time that year.

Fred mentioned a small load on the battery for the ECM but there may be others.
For example, if the coach has a burglar alarm, does it still operate after the disconnects are activated?

How about the LP gas detector under the refrigerator?
If the coach has a Hurricane that will heat the wet bay when temperatures fall, will it still operate if the disconnects are activated?
It is my belief the only way to keep a coach running well is to take it out at least once per month and operate all the systems during that trip, even the washing machine.

The longer they sit the more problems will surface.

David:

This matter of those continuing current drains can vary quite a bit between coaches. I went through this with a previous coach only to find almost 1000 ma. or 1 amp. with a 12 volt TV, broadcast radio, ham radio control circuit, engine computer and the list goes on.
The solution , if you really want to have the full picture is to place an amp meter between the battery terminal and the disconnected red cable. Understand both coach batteries must be disconnected. Connecting to one is sufficient for the test. The same process can be done for the engine battery.

Caution must be taken in using a meter capable of the current drain.
With all the known switches off and the disconnects off a 10 amp scale should be safe, working down to a scale that is readable. It is very educational to test certain devices just to see how much power they take. Take care however with proper scale on the meter. I actually start with a 30 amp or higher meter if I am doubtful of the outcome.

With the drain known a better job of predicting need for recharging can be determined. remember the engine battery is designed to be on top of a charge all the time wereas the coach batteries can tollerate deeper discharge state by design with less ill effect.

Loads before the Disconnects

Hi Folks,

To further explain the situation on battery discharge with the Disconnects set to Off, here are some additional thoughts.

The engine ECM is connected via fuses before the chassis (engine) disconnect. If this battery is disconnected the date-time stamp kept by the ECM will be off by the time power is removed from the ECM.
Any other loads discharging the batteries would have to be connected before the Disconnects. To research this, the foldout wiring diagram is a good start but the wiring diagram pages associated with the disconnects should also be consulted. Any after market connections could have been connected before the Disconnects. I did an ammeter test and did not find any loading other than the ECM but every coach can be different. I like the voltmeter monitoring over time (one week) the best method as it is the least hazardous to perform. The CO and propane detectors are connected after the disconnects.

Ken: If you had a Foretravel I would be interested in hearing your comments on the coach and the company as I have a new 42ft on order since cc would not build a coach with the custom features we wanted. We currently have a 99 magna 36 chefs choice and have really enjoyed it. dave spain my e mail is dspain1@...
