Question about Vivitar 285HV Flash

Need help with Vivitar 285 voltage

I want to make a AC for my Vivitar 285 flash.

I do not have the manual.
Since it uses 4 aa batteries, I am assuming it needs 6 Volts DC. I need to know what pin is the positive.
(When looking at the flash right side up)
Thanks a lot.

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.

Each nicad cell has actually 1.2 volts so 1.2 X 4 =4.8 volt you apply normally.If you want to use external power you must not give 7.5 volts or even 6v .Reduce the voltage by electronics means.Or use 4 D size Nicad package,which are easy to get in local elec.part shop
AC power given on side is not for home AC voltage.

Do i need the battery adapter for my vivitar 283


The 283 and 285 require an adapter to hold the 4 AA batteries. This is because there is an available battery pack NC-3 (NiCad) that works with the Charge-15 rapid charger. Loose AA batteries cannot be used without the adapter known as AP-1. They are all over eBay and quite reasonably priced.

I added 2 standard diodes in series (IN4001 type) and placed inside the dummy battery pack which reduces some voltage and safeguards against wrong polarity.

What is the diff between a vivitar 285 and a vivitar 285hv?


285 has high trigger voltage(+250v) ,where as 285 HV has less than 5.5 volts trigger voltage (which is safe to be used for any digital SLR2_bing.gif). 285 HV has a Thyristor circuitory.

Vivitar 285 not working


You don't need a Manual.
In 285 HV there is only one Power on/off switch.
If that switch is on and batteries are new Alkaline (like duracell-no chepo )or fully charged and working rechargebles,and yet the ready light do not come the flash has defect inside.For sure.

Need battery holder for Vivitar 285 flash


easiest way to get these is search for them on Ebay. they are usually very plentiful. If that fails, most on-line camera stores (B&H Photo is a good one) have them on line to order

Batteries


I use Duracell 2650 mAh rechargeable AA's with my 283 all the time. You may read that 1.2v Duracells or other rechargeables will not work because of the slightly lower voltage (alkalines are 1.5v).

I believe the problem lies not with the voltage, but is due to the slightly fatter profile of the rechargeables that causes a tight fit in the Vivitar battery pack. I find that, after inserting all four (the last will go in really tight), I need to give each cell one more firm push so that it seats properly into the battery pack.

Good luck.

Vivitar 283 flash will not work on camera.


To test everything except the camera, just short the contacts on the Wein protector. If the flash fires, the problem is in your camera, and maybe the protector did not do its job as good as expected.

Good luck
