H & M cut outs

My Safety Minor cuts out on low consumption on 16v AC



The second controller doesn't pull that much, any ideas what to look at?

The overload cut-outs on older H&M units are thermally operated and may suffer from old age.

The cut-out can be adjusted if you open up the unit by drilling out the rivets and replacing them with self-tapping screws for re-assembly.

When you are inside have a good look at the condition of the wiring - if it appears to have suffered from overheating, it may be advisable to replace rather than repair.

Don't do that - you'll invalidate the guarantee! ;-)

Aghh only 35 years old as well

New Safety Minors - where from?

Phil: Can't recall for certain (Years since I used one - I still have and use a DC60 though) - but the 16Vac MAY NOT be isolated from the 12Vdc supply? and therefore NOT suitable for use as a 2nd cab controller, IFF a common return rail (ie single pole switching) is used, and nor double pole????

I feel sorry for H&M - they quietly sit there producing excellent quality products and suddenly, out of the blue they get complaints that their 1953 product doesn't have the same features as their 1959 and 2003 products! ;-) In the meantime, Bachmann have just rolled out their 2 billionth plastic transformer/controller, each with a design lifespan of seven full 0-12-0 voltage control movements.

Mine is late 60s

With main off!

Also if Commander cuts main controller still works

I think I'll drill the rivits this wekend and have a look

Also H&M tend to isolate everything

Your Bachmann controller hasn't completed it's seven full 0-12-0 volt cycles since the 1960s???

I'm sure I've got more than 7 photos of 0-12-0s, taken in 1975... ;-)

Hmm.

Thailand?

Austria. Rack tanks on the Eisenerz, if I've spelt that right.

Are they still running - gotta go buy tickets! :^)))

Done that now

Percy doesn't overload nor does an HST, 24081, but a old Triang 040T does still - will readjust again tomorrow

It is in excellent condition - I might nick it back off the twins!
