CO/LP detector question

When I leave my trailmanor set up in the driveway and not plugged in the CO/LP detector starts beeping a low voltage warning in about three days. There is no other phantom voltage drain that I can find. Does this warning in this time seem too fast given a standard battery? It seems like it should last longer than this to me. Any thoughts?

Thanks,

Yes, it seems much too soon. I'm convinced you must have some phantom load somewhere, even if you haven't found it. To find that phantom load, you really need digital voltmeter, set to the DC current range. Remove the positive connector from the battery, connect the DVM's red probe to the now-empty battery post, and the DVM's black probe to the connector that you just removed from the battery. Now the DVM will show you how much current is being drawn from the battery - and I bet it is not zero.

Now, while you monitor the current with the DVM, open up the converter's front panel, and pull the fuses one at a time. This will tell you which circuit is the culprit. You may find that there are several circuits contributing to the problem. There are many phantom loads in any RV, including the TM.

If you don't have a DVM, they are available in many places, for very little money for a simple one. If you have a Harbor Freight near you, it might be $5-10. Or a big box store or WalMart might run $10-15.

How old is your battery? Do you know condition? Even newer batteries can give poor performance. Just a thought.

Thanks for the input. Based on another thread, I think I may disconnect the radio. We do not use it anyway.

I also agree that the battery may need changing.

Rather than disconnect the radio, you could just put a switch in it's circuit so that power is interrupted when not in use. No?
