a year ago I had the same situation. I'd suggest you charge the battery and then when done, use your multi-meter to read the volts across it. Start the bike. Read the volts across the battery when it is running -- at idle, at 3k rpm and at 5k rpm. If your system is not putting enough charge into the battery while riding, that'll help kill it off. If you are not riding it at all for the 7-12 day period you mention, then each day check the voltage across the battery and see how much it changes. Get the battery load tested at a place like Advance Auto. That'll tell you if your battery is able to hold a charge. In my case, I needed a new battery.My battery runs down to completely dead after a few 7-12 days of sitting without a charger on it. Is there something that runs all the time or is it just mine?
Interesting. Most accessory lights use a relay which is activated by a small current (around 70mA to 100mA). This is supposed to be connected to a 12V source which is switched with the ignition. This way without ignition the current is truly zero (Relay open).I agree, but, when i check it with a multimeter there is slight draw in resistance to ohms to on the meter as opposed to all the other battery connections main and aux wires (power socket and charge plug). None of the other wires, even the main ground wire shows a reading except the Denali light wire. I suspect a short somewhere in the Denali wiring, i just haven't gotten the far yet. Waiting to see if the disconnected Denali power wire will affect the battery draining down over the next couple of days. If the battery stays charged up then i have found my culprit, if not then the search continues.
Yes this can definitely happen. The charger will have a constant current even if no load is detected. Depending how much the low current was a design consideration or not the current could be significant enough to kill your battery within as little as week or two. It really depends on the unit you have. To know how much, just put an ampere meter between the battery and the (likely red) wire of your charger and see what it says.Have a USB charger port installed, does battery discharge if connected from bike? I have had "2" bad batteries in a row before (don't cheap out on batteries), and they do some weird things sometimes.
