Be careful, new flashes can be just as bad. The Vivitar 2800, a nice cheap flash has 170V brand new.
rite, usually, simple flash use the main internal high voltagefor the trigger circuit (that's why it's cheap).They areperfectas optical slave though

Also, use a digital meter or an analog one set to read 1000v scale. Reading a analog meter at 10v scale will give wildly inacurate results
... and use an analog meter with 20kOhm ~ 50 kOhm per volt .
sometimes , a low impedance meter will simply trigger the flash when we try to measure
