Its unlikely that you have damaged it, did it ever switch under its own power, if not then its possibly not aligned correctly. if it did then I would guess its possible you haven't wired it correctly, so check all the connections again.

Alignment, Ted.

It's a weird one.

I totally agree with you Steve - it SHOULD be alignment. However, I'm getting pretty good at this - this one is around number 10 or 11 on my motor quest. And it's about 1 inch from the edge of the baseboard, nearside, and at 90 degrees. So alignment is pretty straightforward.

Yes. Away from the baseboard, the motor flicks under its own steam.

I unmounted it and remounted it. Exactly the same. Weak in one direction.

In the end I removed it and replaced the motor and that one worked flawlessly.

I'll probably put it under another set of points and see if it was just an anomaly.

Ted, are you attaching the Seeps with screws? If so just slacken them off a fraction - I found that can sometimes help.

As Steve has typed slight over tightening of the mounting screws will bow the pcb and stop the points from shunting across, all my Seeps when i had them could move a little....

Thanks guys, I could move them manually, using the accessory switch underneath. They moved quite comfortably.

Well in the end I took that iffy motor away and replaced it, and the replacement worked fine.

I got to the end of the marathon today and my last motor was probably the easiest to fit in accessibility terms so thought I'd try the dicky one from earlier again.

It displayed exactly the same symtpoms when placed under another turnout. So took it out, replaced it and the replacement was fine.

Very odd as it worked fine when unattached, but never when placed under a turnout.

On the positive side, phew, they're all done.

Seep PM1 failure to throw is usually due to alignment issues or over tightening or a lack of correct wire size. However, I've had some Seep PM1 motors where the washer sticks fractionally under the plastic coil former. It then takes a hefty pulse to free the washer. In the end after replacing them I bonded a small strip of plastic across the bottom of each coils support to prevent the washer getting trapped. Motors worked a treat then!

This one's actually a Peco PL-10E (I do have some SEEPs but they work OK).

It's the only one I bought used second hand. Maybe there's a lesson there.

I had a few other SEEPs and PL-10s fail to throw at first, even though appearing to be perfectly aligned. One I even unscrewed and removed from the layout, only to discover I'd left the bit of card in that I'd used to keep it centred.

Well, it kept it centred at least. We live and learn.
