How do i charge my vivitar 3188, what valt charger?@

connect a multi meter across the battery terminals and set on volts dc there should be 14.5 volts across the posts when the charger is on check for the dc notice on the dial as if the rectifiers in the charger have failed , you will get an ac voltage and that will not charge a battery

Try another Cord/charger, with the EXACT same power specs, without the battery installed. If it works on the AC/DC cord/charger, replace the battery with a genuine battery with the exact same power specs.

OK. But I don't understand what the problem is.

AC adapter (Charger) is burnt out, by a new one.

Look at the old 'charger'.
Look at the label.

Input: 100 ~ 240VAC/50 ~60HZ.

100 to 240 Volts AC, at 50 to 60 Hertz. (Cycles per Second)

Output:
This is what you need to know.
What is the output voltage of the original charger?

Example;
Output: 19VDC @ 4.63A

19 Volts DC at 4.63 Amps. (Amperes)

Your charger MUST put out 19 Volts. (For the example)
It WILL be DC electricity, so don't worry about that. (Direct Current)

[Your 'charger' is more than that. More than a charger for the laptop battery.
It is also a Converter. It converts the 100 to 240 Volts of Alternating Current, (AC), into a low DC Voltage.

Plus it charges the Battery, WHEN needed ]

Post back in a Comment as to what the exact query is.

Hi -

It is not uncommon for some devices to be unable to accept a charge while in use - especially if not using the supplied charger. This is because the amount of power required to USE the device (your iPhone in this case) exceeds the amount of power provided by the charger.

If trying to make a call, you may be able to coax your iPhone to accept a charge if you shut down un-needed services such as wifi, GPS and BlueTooth radios along with turning the brightness of the display down, etc. This greatly reduces the power requirements of the phone; and if the charger is powerful enough, it will begin to slowly charge your phone. The charge rate will be significantly lower - requiring a longer time on the charger - whenever the phone is being used AND charged. Once the phone is no longer being used, the charge rate will immediately increase, since AC power no longer has to be divided between charging the battery and operating the phone lights, radio, etc. This shortens the amount of time needed to recharge, significantly.

Whenever possible, use the the supplied charger - or one with the SAME voltage, polarity, and voltage type (AC or DC). The amount of current or wattage should be the same or greater than the original. Most phones use USB connectors and are 5 Volts DC. USB standards call for between 1/2 and 1 Amp current. Since watts is equal to volts x amps, this example would represent a 2.5 (if 1/2 amp) to 5 (if 1 amp) watt charger. If you could find a higher wattage charger while still maintaining the DC voltage requirements, you would be able to use and charge the phone at the same time.

I hope this answers your charger question & good luck!

If you light is charging when you use the 12v automotive charger but not when you use your AC power transformer, my thought is that you might have a problem with your AC charger, not with the light itself. I have AC/DC transformers from the 1970s that still work fine, but I have had numerous modern AC/DC transformers burn out on me in recent years.

One easy test is to use a multimeter to measure the output voltage of your wall charger. Place one test lead on each of the charging terminals (i.e., one inside the barrel and one outside the barrel, if you have a standard coaxial charging port) and check the DC reading. If it's zero--or anything less than 12 volts, actually--the charger isn't working correctly. The problem may be a torn or cut wire or something actually inside the transformer.

Replacement chargers can be found at Radio Shack and other stores. You may also be able to score a cheap replacement at a "dollar plus" store or even at a second-hand shop. Make sure that the terminal polarity is correct on your replacement charger or else you'll fry the batteries in your light.

Good luck!

You need to check the powerpack voltage AND whether it's AC or DC. If DC, the polarity needs to be correct too.

You should not put AC voltage into DC circuits.

A better directions:

Open open the 285 and solder two wires(red = positive; black = negative) then snake it out to AC connector(this needs to be removed).

Buy 7.2V plug set from Radio Shack or remote control car stores.
Buy 7.2V Battery and Charger.

This will be better than buying the Quantum & cable battery.
It will also wake up the flash faster than using the Quantum.
The total cost should be less than $85.00.
The battery is about 5X stronger than those 4 AA and they do last longer.
