The garage that is currently looking at my '32 GTS-T (RB20DET) needs to test the resistances of the power transistor.

They only have the information to test a 300ZX and this is showing that the power transistor is faulty.

Does anyone have a flowchart or diagram/information for a power transistor component test.

It might be a long shot, but I'm using the words of the mechanic. I need it asap! Thanks!

Can you possibly put up a link to the 300ZX ptu test diagram?

I have the info here for the RB20DET's PTU, but the info is in very poor print... really hard to make it out. :(

Possibly the 300ZX could use the same ptu as the GTR (which is different to RB20DET btw) ... but not sure.

Sorry i cant give you a straight answer mate... but if i can see a diagram of the 300ZX's ptu, maybe the results and the testing procedure will be the same?! :)

That was the thinking of the mechanic too. I've not got the 300ZX diagram to hand - though I did find the R32 GTR manual with the relevant information for the PTU. I think I'll be needing another at this rate :uhoh:
