P38 GEMS Coil Packs

When they go faulty do they fail on just one output or both, I seems to have a coil pack that is providing an output on one turret but not the other? Been swapping leads around and proved it, I have another on the way but it did seem strange to me.

Hi
on a 2 pole coil pack to test them you need a plug in each lead that is earthed, I have spent hours over the years testing just one end with the other floating . . . . ie both work or both don't.
actually having a bit more think about it you could have a dead short on one post to earth, but that can be checked in 30 seconds with a multi meter.
best regards
Mike

Reason I ask is that's if I swap leads 1 and 6 the fault moves, it's the only common point as far as I can see

I guess it depends on the fault, but as has been said, if one has shorted to ground (or broken down so it sparks to ground internally), then you could get a coil pack that appeared to only work on one output.

New coil pack it is then, the money pit continues to live up to its name

All sorted turned out to be a bad joint on one of the wires going into coil pack 3, so I now have a spare GEMS coilpack
