Hello. I know this is a long shot, but I am looking for the technical or service manual for the YS-250Pro strobes. I have two of them. One of them is not charging the caps (no charge whine). The other charges but is no longer firing with either optical or test. I am unable to test TTL. I would love a schematic on these rather than reverse engineer it and figure out the issues with them. I do understand the safety involved with a strobe circuit.
Thank you in advance.
Some good news on the battery packs, as I have had to rebuild mine. The batteries contain two safety features. One is a thermal cutoff, this is under the rectangle protrusion. It is easily replaced and sourced. The other is the varisistor. This is used only for charging, not for the strobe use itself.
