Hey all ~

Is it possible to test a voltage stabilizer to see if it's in good working
order
if it is not mounted in a car, just a "loose" stabilizer? This would be
either
the TRF 1488796 or Moss 133-555 (negative earth).

Thanks!

Dave

Hi Guys,
  I tried the solid state voltage stabilizers and have found them prone to f=
ailure.  Luckily I held on to the old reed stabilizers the solid state volta=
ge stabilizers were to have replaced and have had no issues with the reinsta=
lled 50+ year originals.  YRMV=E2=80=A6

Probably it is broken

Time for a new one.   We discussed this recently and devised a decent improved design.  Perhaps someone made one and made an extra one too.  (The added cost is low)

These commercial units are insufficiently protected and don’t even have the specifically recommended filtering.  

I made one many years ago and used the device specifications re: filter capacitors.  And I avoided aluminum electrolytics because these have a limited lifetime especially around heat.  But I don’t have any spares any more.
