Flashing battery icon

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

Flashing battery icon

Post by Bullethead » Sat Oct 19, 2019 6:56 pm

During a warm up idle this morning, I noticed a battery icon flashing on the led speedo screen. Persisted on all the led screens. No alternator light noted. Revved the engine a bit and it went away; back flashing again when back at idle for a few seconds. Figuring it’s a low charge rate warning. Charge rate as per speedo reads 11.7 +/- at idle...I always look for 13+...but I don’t know how accurate the speedo might be. I’ll be back home Monday, hopefully, where I can get a meter on things. Anyone had any experience with this?

I don't have LCD speedo Ural experience.
Me think your battery is low. Your alternator and charging system is working ok since no alternator light noted, and when revving battery icon goes away. Put your battery on tickle charger or go for a 20-30 min ride.

(Low, idle RPM usually does not charge the battery).

When the mercury is above 50F or so, my charge at idle (from a cold start) is 12.0 - 12.2 volts. Below 50ish, the charge at a cold start idle is 11.8 to 12.0, depending on whether or not I turn the on the heated grips and the sidecar LED driving lights (which are intended to compensate for the cold and the dark, in turn).

Warm engine starts, even on cold days, return a charging voltage that has not been less than 12.2 volts or so...and that's with the heated grips turned on straightaway.

Only when moving will the volt meter illustrate a charging voltage that increases to and maintains the correct and constant charge rate of 13.9 to 14.2 volts.

I'm careful to drain the 20W-50 and add 5W-40 when prevailing temperature trends indicate that I should do so. This is in accordance with the Owner's Manual. More to the point, the lighter oil prevents hard starting and too-low idle speeds (which may possibly contribute to substandard charging voltage, at least temporarily) on truly cold days.

To date, I've not set see a flashing battery icon on my Acewell speedometer. 2018 Gear Up with original battery here.

My personal standard for 12 volt batteries, in any application, is a 5 year service life. Just a thought.

Lofty pretty much nailed it.

I do get the low batt light in the am fairly often in cool weather. As a daily rider with a short commute involving a lot of stop and go I don't spent a lot of time at charging rpms vs draining rpms. As such I installed a Euro spec headlight switch so I can turn off the lights while warming up, on our long driveway, and large parking lot at work.

I got the MIL come on this morning after the first cold start. Ditto. Low battery. (It stored an error code the last time, same behaviour.)

Battery does not charge at idle so you won't see 13+.

Thanks all. Warmer today and no recurrence. Still, I’m going to get out the multimeter for a thorough check when home tomorrow. Still under warranty so I’d sooner find out there’s a charging system glitch now than later. Once again, too grateful for your advice.

When you get out the multimeter, also get out the Ural Owner's Manual and read it. You will find out that the "battery icon" that is flashing IS the alternator light. Kinda' logical isn't it? I suspect that this is normal operation, as alternator may not be spinning quite fast enough at idle to keep the battery icon turned off. My '17 GU does this occasionally. I expect the multimeter will show that you are chasing a non-issue, but it's good that you are so observant. Let us know what you find. Best of luck.

Gee...forgot about this issue. Indeed, checked everything with the multimeter and found all nominal. However, hope I was clear about where the battery icon appears. This is a flashing battery icon that appears above the mode readout on the led portion of the speedo NOT that on the face. Anyway, that was the first and, so far, last time it’s happened. However, cold-weather riding ahead. Didn’t have the issue last winter....rode all through....so I’ll keep an eye out for any recurrence. Thanks for the reminder.

You don't say where you live? Heat can be an issue and while its early for a 2018, a less that stellar battery form the start (I have one, its ok but its like a 5 year old battery the way it acts)

Ok, there is a variation and knowing your engine speed helps that a lot.

Ural does true idle (not warm up) of 900 or so (varies). At that slow a speed, you are not going to be charging. I don't know what voltage the battery light comes on but its going to be lower than 11.7.

Initial idle is 1100-1300. That is enough to charge, maybe not full out 14.5 but above 12.5.

Up above 1500 or so it will output 14.5 volts more or less a few tenths.

So you fire it up cold and the idle is higher and voltage is at least ok but as the engine actually idles down then it will drop to no support level.

Electrically you have to cut lines of force to generate power and speed is the best way to do it in a smaller package (Ural alternator)

So, if at higher idle you have decent voltage and ramp it up to 3 grand and its 14.5 your system is fine.

You may be flirting with a battery that is less than full capability anymore (they do deteriorate over time and cycle batteries are small and the worst) and it may dip into low enough at a true idle to light the light.

Hotter the place you live the shorter your battery life. Check the sells for fluid level.

When you first turn on the ignition with NO engine, your battery should be 12.8 or so. If its there but then drops below 12 fast, its not a fully capable battery. You should be able to sit there for 10-15 minutes with headlight on before it drops below 12 volts.

Biggest issue with batteries new is where and when they are filled. If they sit too long before running after filling, they sulfate up and you can never break it up after a point. I suspect that is my issue.

Interstate batteries are good, not sure if they do it with cycle batteries but the local warehouse for regular batters does not fill them till they sell them or send them to the local stores. I believe they use Yuasa for cycle batteries and those are good. Local auto parts place I would not touch.

Honda at least used to sell batteries with no fluid and you added the mix to them at home. Same idea, don't let them muck up sitting there.

Thanks for the input. Heat won’t be an issue for a while...I’m outside of Buffalo. First significant snow this morning. 😣

You are welcome (output? - grin)

I ran a rough check. At about 1800 RPM the alternator is putting out 14.5 volts.

I have mine hooked up to the RPM wire in the Head so I can't see both at the same time. That is normal as you need some RPMs to get max out of the alternators.

If they actually idled at 1000 I think you wold break even (12.5 or so) but they drop to 900 and a tad less. Non worry or keep the idle up a bit at stops with the throttle. Often I will just turn it off for a long light.
