What brake light??? What did you do exactly, where did you put this dc volt amp reader???? Check the bulb first.

Bosch 1197311213 EL14V, how can I test to determine that my alternator voltage regulator is still good or bad?


if the charge light is going out after starting then it is charging. Next step is to use a multimeter that has the ability to read volts DC and volts AC. If it shows Volts dc 13.5 to 14.5 volts at around 2.000rpms then it is good . If it shows volts ac then the rectifier in the alternator is not working and needs replacing . Next place an amp meter in the line to the battery and read the amperage .It will read in a ratio to the volts DC so if the volts Dc is up around 14.5 then the current flow will be low but if it reads 12 volts then the current will be high. If the volts dc is over 14.5 volts say 16 volts then the current will be high as the regulator is not controlling the current out put. If this sound daunting then go to an accredited auto electrical shop and have it checked out

It does not seem to be charging the batteries. 12 volt lights work good for about 2 days then go dim until I put a charger on the batteries and bring them back into working order. The battery connect...


The Parallax 7155 converter should not require battery support for any 12 volt load amperage that is less than the maximum amperage capacity of the converter. A standard RV incandescent 12 volt lamp draws about 1.5 amperes for each bulb. With the battery disconnected and other 12 volt loads off, turn on lamps (not fixtures) and calculate the number of bulbs which can be turned on. If you run out of lamps, turn on vent fans etc. The idea here is to try to get to 55 amperes of DC load if possible without going over 55 amperes. At a sustained DC load of about 25-30 amperes or higher, the fans should cycle on continuously after about 5 -10 minutes. Lamp brightness should be normal and the measured voltage from the converter should be above 13 volts if under 55 amps of DC load. If the voltage drops with only a few lamps on, a converter issue would be likely.

Diagnostic tests an RV technician should make would be to:
1. Disconnect the battery system.
2. With the converter system powered on, measure the DC amperage with a DC ammeter capable of reading at least 60 amperes DC from the blue lead at the DC fuse panel terminal VCC.
3. Measure the DC voltage at terminal VCC and DC ground.
4. Record both readings.
At any DC load amperage less than 55 amps, the voltage should be above 13.0-13.2 volts DC. This method should take out all guesswork and confirm a DC converter section issue or not.

Check the battery is charging correctly. the voltages at the battery should be engine off- about 12.4 volts DC . Engine running at about 1000 rpm the voltage should be about 14.4 volts DC. if these voltages are down, you have a regulator, rectifier or alternator problem.

I was curious, if i put my 2055 scanner on 12 volts, instead of the required 13 volts, will it hurt it?


You won't damage anything with 12 volts. Equipment built for use in automobiles will often have a DC input marked 13.8 volts because it's the voltage delivered by a fully-charged battery. But any supply around 12 volts will work. Just be sure the supply has enough current available (around an amp should be fine for a scanner), and that you get the polarity right when connecting it.

What polarity is the input on the ion IED04 DIGITAL DRUM STAION BY ION. I HAD TO GET A POWER ADAPTER AND DON'T WANT TO DAMAGE UNIT. THERE IS NO PICTURE TO NOTE POLARITY.


There is NO POLARITY to worry about since you MUST use an adapter that supplies 9 volts AC at around 850ma. You CANNOT use a DC adapter with this unit and have it work. Putting a DC adapter of 9 volts on it won't damage it, it just won't work.

AC output adapters are harder to find.

The battery keeps dieing and the break lights aren't working


If the battery keeps dying, you need to have the battery checked. Take it out of the bike and take it to an automotive parts store. Ask them to Load Test the battery for you. If the battery is good, you need to check the charging system. To check the output of the charging system, first, fully charge the battery. Then connect a voltmeter to the battery, red meter lead to the positive post, black meter lead to the negative post. Put the meter's function switch in DC VOLTS, 50 VOLTS range. Start the engine and bring it to a high idle. The meter should read 14.5-15.0 volts. If not, you need to check the stator. Since you didn't tell me what year or model your bike was, if you'll respond and supply that information, I'll tell you how to check the alternator output.

Also, tell me whether it's the front brake or the rear brake that doesn't light the brake light.

Good luck

I just need to know if it has a 12 volt system?


Peek onto your battery see if you can identify what kind of voltage it holds, I believe generally speaking all 2 & 4 stroke petrol motorbikes and cars uses 12 Volt system, most diesel engines uses 24 Volts. Good or excellent enough?

What should be the percentage of the battery when its fully charged on an aprilia 125 rs


If the system is 12 volt, which I think it is, a new battery should read 13+ volts fully charged. Note! You can have 12 volts, but low amps. You need to ideally charge the battery and put a load tester on it to know the truth about the condition of the battery. Chaz Moto DC

20-Volt DC Power Supply instead of 12-Volt amp


Here's a few things that come to mind. An auto charging system will operate normally from about 11 Volts to about 14.5 Volts, depending on what is operating (lights, blower,etc), and whether the vehicle is at idle or not. Most car amps will operate from about 10.5 to 16.5 Volts, and outside that range, they will probably shut down.
Another consideration is your 20 volt power supply. You didn't mention if it is a DC power supply, but it needs to be. The other factor is its output, meaning its amperage rating. I'm figuring it will need to put about 5 amps, at the least, for the Sony to put out some watts. I think the line fuses of the Sony are rated @ 25 amps each.
I don't like this type of situation, because I want to say 'try it and see what happens" and I want to say 'don't do it, something may blow".
If you decide to try the 20Volt power supply, maybe if you put smaller rated fuses (say 10 amp) in the Sony amp, they will act as a fail safe. Good luck!
