Any idea where I get a replacement charger for a Metz60CT4


EBay, if that's what you want. The metz "chargers" are just 7 volt ac transformers - they supply 7 volts to the battery pack which has the actual charging circuit in it. I haven't pulled one apart yet, but I'm guessing they're very rudimentary chargers. Depending on what you're using for a battery you might want to use a modern external smart charger. I use $20 AGM batteries from batteries plus (instead of the $80 metz batteries) and use an external charger from WallMart on them. It's quick, lets me see the current charge state, won't overcharge the battery, and works on my car and boat batteries too.

I have two Mecablitz 60 CT batteries. They are about 10 years old and have not been charged since March, 2004. Should I dispose of them or can they be repaired for a reasonable cost?


The couple of dryfit batteries I've looked at have been shot. I don't know how old they were. Take a decent modern battery charger (the ones at WallMart are good enough) that will handle 6 volt and AGM batteries. Clean the contacts and jury rig a way to connect the charger to the battery terminals. If the charger doesn't register anything, it's likely the batteries have died. They will actually completely dry out inside, becoming inert. I've used $20 AGM batteries from Batteries Plus and they seem to work fine (though you either need to make a battery adaptor, or cut out the side of the battery pack to get them to fit.

Does the TR-2000 work with a vivitar 285? What cable do I need to buy?


TR 2000 gives two output ^ volt and 330 volts.
Whereas 285 HV uses 6 volt and 110 volt AC

I am running my 285HV with external 6volt battery pack.sort of this type.

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.

The filament on my unit may be burned out. Can it be replaced or is the unit now trashed?


If the tube is burned out, then you may be better off if you trash that unit and find a new flash. the electronics involved are high voltage and dangerous. So 1- if the part is available, 2- you can find somebody to replace it, and 3- that is the problem, not something else. The age of the flash is going to hinder you.

No power for my 'old' Vivitar 285HV Flash


I've got three 285HVs and have had this problem. Obviously, make sure the batteries are good and the door and inside terminals are not corroded. The whine sound that you usually hear is the high voltage circuit. the reason it changes pitch is that the main capacitor is charging. As the charge gets greater and greater, the pitch with go up as the circuit changes the power being fed to the capacitor. If you don't hear the "whine" then it's either the HV circuit isn't working (probably not) or the capacitor has gone bad. These things are sealed but can decay internally due to their structure. Usually this is due to the dielectric components breaking down or the electrolytic goo drying up (usually what causes it).

Sometimes, you can let it sit with good batteries and the switch on to see if it will eventually start to charge the cap. Most of the time tho, this is an indication that the capacitor or the charging circuit is dead. It can be repaired but sending it off will usually be more expensive than replacing the unit.

Be sure and rate me!!

Need help with Vivitar 285 voltage


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.

Vivitar 285HV Stop Working


There is nothing wrong with your flash unit. The regular AA batters are 1.5 v volts each- if 4 batteries are used that is a total of 6 volts for proper operation. The rechargeable batteries are 1.2 volts each and 4 will get you 4.8 volts- thats 1.2 volts short and that is probably the root of our problem .

Try recharging you rechargeable batteries and put the im one more time- if the same problem happens you will have to stick with standard AA batteries. There external 6 volt packs that will work with your flash unit0 the are a bit of an expense at first but you will save on replacement batteries in the long run,.

Will a Vivitar 285HV fry my Canon EOS 40D? I'd like to experiment with a Vivitar 285HV as an on-camera hot shoe flash. However, I'm reluctant to proceed because of conflicting reports about voltage...


Personally, I would not try it. While the Canon has a protection system built into the camera, the trigger voltage on the Vivitar is pretty high. I have had good results using a 283 on a slave shoe, you will have to stop down more with the extra light
