Can I use my old 283 with the new digital Nikon d70 without fear of a short in the electronics?

I have been Googling the Vivitar 283/285 voltage issue for use with a Nikon D300.
I am confused about measuring the discharge voltage.
Using a dial volt meter, set in the 10v DC range, when the flash discharges, the needle only deflects briefly to about 3 or 4v. Would this be correct and therefore it is OK to use my 285 with the D300.
Many thanks for your advice,
Rex

ApprenticeThe Vivitar 283 was manufactured in China & Japan over a number of years & the specifications did change over this period.
The older Vivitar flashes had a voltage on the shoe which could reach 150 volts whilst the later ones had voltages of only 5 to 9 volts.
If you have, or can get hold of, a small voltmeter then you can measure this voltage.
Turn on your flash & let the unit charge up to 'ready' & connect the meter between the contact in the centre of the shoe & the little contact tucked away in the lip of the shoe. (DC volts not AC) There is no danger to you in doing this!
This should tell the voltage on the shoe of your unit & if it is 15 volts or less, it will be fine with your digital Nikon camera. If more than 15 volts than best not to use it.
Hope this is of some help!
