Hi everyone, I'm hoping you can help me out with this issue. I have a flourescent interior light from a vintage VW camper van that doesn't work. I have found a small diode (possibly zener) which only has ITT markings and a double line at the cathode end, which i believe is faulty on the driver pcb.
When testing in ohms mode with the multimeter, I get OL with the red probe on the cathode (expected), and 2.1Mohm resistance the other way way round.
This particular board is a single transistor type (which after research, I have found this to be the worst way to drive a flourescent tube, bigclivedotcom explains flourescent tubes in an excellent youtube video).
If the diode is faulty, is there a way I can find the original value? I believe it is quite an important part of the circuit.
