Hello kingfisher1

You can find the owner's manual for the Minuteman Pro 520 UPS HERE.

You can find support for Minuteman UPS' HERE.

Refer to page (4) of the owner's manual for a description of the UPS' front panel controls and indicators.

Looks like if the 4th LED from the right is on, you need to replace your battery.

Left to Right the LED's are:
(1) Online; Boost; or On Battery (depending upon the symbol that is illuminated)
(2) Fault
(3) Overload
(4) Replace Battery

Please, let us know if you have any more questions, observations, comments, etc. on this topic. We are happy to help.

Thank you

I placed a new battery to my activa bike on 13/05/16. After two days while the bike is in running, horn , indicator lights went off slowly. Then bike also went off from moving.

did you leave lights or key turned to on position or the battery didn't have a good charge when you parked it. Did you kick start the engine? Bike may need a tune-up.

Back lights, park assist, rain sensor, interior lights on console and right rear indicator stopped working the same time. all fuses good and only brake lights work. head lamps also working

does car drive.?
if it runs , is the CEL lamp in cluster out
is the charge/battery./GEn light OUT?>
is this USA spec car, or where? (Wiring varies by country)

check both fuse boxes, not just one?
2007 i think they went to 1 box under hood.
but 2005 is many box car, IIRC.
you need to scan the PCM first.
no scan tool?, no joy,
if it shows DTC errors, you need to post those first.

i have the FSM, ill look at one fail.
WK jeep Gen 3
ill do backup lights, as i cant figure others out, "rear indicator" mean R/R blinker or turn signals dead?

id need to drive car. (need all things working and not, , not just cheery picked)
id need to see if all cluster warning lights glow key on
and if i turn the HL switch to park does the cluster lamps glow?
called illumination lamps in cluster.
the GC is very complex electrical, not like some old CJ.
very complex.
(no problem) but we scan it first. why not do that. so we dont have to node test , vast things with my meter..... volt meter....
ok , no scan tool, for $10 (elm costs that and works)

do all exterior park lamps work (you said heads work but parks ,are they all good)?>
ok im in chapter 8W now, wiring.
100 pages deep....
back up page, 54-1, fuse 9
if fuse one is hot both sides the lamps glow.white.
the relay is controlled by Module front control (MFC)
if the model fails to close the relay , that means it was never told to.
if the PCM or BCM fails to see reverse selected or fails to communicate this fact to the MFC then the PCM or BCM
sets errors, called DTC errors.
it will tell you, for example comms are dead.
or the MFC is not talking
or other errors related.

your car has a network, if its dead, things die.
the network must be working right.
that takes just a fully charged battery, is it.
is battery at 12.6vdc rested?????????

no 10v. but 12.6 volts. (dont own a $10 volt meter? yet?)

the MFC is inside the MIP, module integrated power .
the MFC is messing up, my guess.!
it runs backups and blinks, even in the rear. dispite its name FRONT.
Id say the MFC is not bad, it;s
1: scrambled? (lost 12vdc power?) to it or weak battery.
2: comms to it are failing. (seems its half working,, implying to me garbled data transmissions to it , on the network.
scan it, or never know... why.
it can be reset, by pulling fuses. to it.
sorry for crapppy photos, on fixya,. they shrink it to near useless...

Greetings Gurus. I have Makita charger model DC18RC, battery model is 18v BL1815...manual is of limited help. I'm trying to understand what the indicator lights mean, what the time is for charging,

I agree that the pictographs are not very helpful. You probably have one of the new chargers. I have an old one, which is a little easier to figure out.

From top to bottom

1. The flashing green light with the electric plug indicates that the unit is plugged in and ready to go.
2. The flashing red little fan means that the battery is too warm so it is just cooling it and not charging it at that moment.
3. The solid red empty battery outline means that it is charging but hasn't got very far, less than 80% full.
4. The mostly full battery outline with both solid red and green lights at the same time means it is 80% full or more
5. The full battery outline and solid green with the musical notes means it is full up.
6. The broken battery outline with flashing red and green means you've got a broken battery.
7. The yellow light with the wrench means the charger is "conditioning" the battery, whatever that means.
8. The yellow light with the fan means "cooling abnormality."

Hope this helps

Try replacing the fuse for the backup lights. Mitsubishi Galants have had this problem happen a lot as well. Don't know why it blows, or why the backup lights also are used for the same circuit, but that should fix your problem.

Have an orange light on my keyboard and don't know what it's for

That will depend on the manufacture and features of the keyboard. It could be anything from an indicator that a wireless keyboard is connected to the receiving device to an indicator a wireless Keyboard needs new batteries or that some function like the number pad is active. You will need to look up the light in the operators manual. In most cases if you don't have that manual you can download from the manufacturer website.

Package, manuel and receipt were accidentally thrown away and we don't know how to charge the radios. They work, but are running low on battery power! They have a power supply cord that you plug both...

From what I just read on the Cobra website, you may be misinterpreting the battery indicator lights:

My radio keeps showing low batteries

This may simply be a matter of misinterpreting the low-battery indicator. We use two different types of battery indicators:
  1. Battery Level Indicator: This battery indicator is always visible, and has several segments. When all the segments are lit, the batteries are full. When only the last segment is lit, the batteries are almost exhausted.
  2. Low Battery Indicator: This type is usually NOT visible. It only appears when the batteries are low, at which time it flashes on the display to warn you of a low battery condition.
Please note that when you turn on your radio it first performs a display test. Everything on the display will light up for a few seconds, including the Low Battery Indicator. This does not mean that the batteries are low. After a few seconds the display test will end, at which time the Low Battery Indicator should go away.

Here is a link to the Manual for your radio:

It is a PDF file, which requires that you have Adobe Reader or equivalent installed on your computer for it to open and display properly. If you don't have it, it can be found here (it's free!):

Good luck!

I recently puchased an EGET MO-H04CD portable oxygen concentrator and I am having problems charging the Lithium batteries that were supplied with the unit. There are no instructions on how long you have to...

Red light normally means that the battery needs charging. The green flashing light can mean the battery is charging or has charged, and the same with the solid green light. Green in this case is good.

Charge the unit overnight and see what the indicator state is. It should not take more than 8 hours of charging for a Li-ion battery. Once you know what the full state light looks at, then you can tell what the charging indicator looks like.

In all cases, ensure you are using the proper charger with the unit.

I need to know what the gauge lights mean on my 2002 Honda 954RR i bought it used and didn't get a manual by gauge lights i mean the all the engine warning lights.Thank you in advance.

Should be a neutral light - indicating when you are in neutral, a high beam indicator, turn signal indicator, a oil pressure indicator and maybe a high temp indicator.

I suspect the oil pressure light will be on when the ignition is on but the engine not running - just like in a car. The neutral light ... I use mine as a guide. What I mean is when it is illuminated, I know the lamp works. I am still leary about depending on it 100%, though through the ownership of a 1/2 dozen machines over the past 30+ years, it has not let me down.

There may be other indicaating lights on your motorcycle.

Turn signal lights do not self cancel, BTW, you must press the switch IN to cancel the turn signal.

If you will go to the Honda Riders Club (use your favorite search engine to find it) and join for free, they will let you look at a generic service manual. If you pay the couple buck to join, they will give you access to the service manual for YOUR bike, according to information posted at the web site. You can even download and print the manual if you like.

Good luck with your new bike.
