Testing a Ikelite Dual Sync Cable

Dear guys,
I'm testing a Ikelite dual sync cable for a friend, and it looks failed because it doesn't have continuity between all the pins.
Between the Housing end, and the primary strobe end, just the POWER for TTL circuits is opened (there is not continuity).

The fail we detected with a camera testing is that the strobes only fires on manual mode, but not in TTL. ¿Is this coherent with the POWER wire opened we found?

But, testing continuity between the housing end and the secondary strobe ends, just the Ground and the Trigger shows continuity. ¿is this normal, or is a fail too?.

Can I open the cylinder where the cable splits in two to check where the wires are opened, and may be repair them?

You will have 3 wires connected on the secondary strobe (red band) and 5 wires connected on the primary strobe.

Thanks!
What 3 wires goes to the secondary strobe?

Trigger, ground & quench.

Thank you my friend!
I think that I can repair the cable without compromising the pressure seals. Thanks for the information.
