Metz 60 CT-4 Always fires full power problem.
I registered here as this forum has been knowledgeable and helpful to similar questions in the past.
I just purchased a Metz 60 CT-4 and it always delivers a full power flash, regardless of settings. ie. All manual settings or automatic, it is always full power.
It has worked a few times properly so this gives me hope it may just be a dry joint or similar.
I have other 60 CT-4's and I have swapped out every component individually to isolate the fault to the power pack. I can swap the flash head, lead (and lithium battery) to a good pack and it works perfectly, and I can swap the other known working flash and lead onto this pack and it behaves in the same faulty manner. I have tested both outputs from the pack and both behave the same. Both outputs also have the right voltages on them (OV, 7.8V & 356V).
I am hoping someone may be familiar with servicing these units and might be able to point me in the right direction? I am handy with electronics but need a little guidance to get started. I am aware of the need to drain the dangerous high voltages and that all work performed is at my own risk.
Further does anyone have, or are aware of, a service manual online? (I have the owner's manual).
Thank you kindly and all the best!
