Our large club layout has two Wangrow dual 5 amp boosters (for a toal
of 20 amps divided around the layout). These have worked flawlessly
for about 4 years. They have responded to occasional shorts properly,
shutting down power until the offending equipment is located and
removed. Last Friday in the middle of routine operations, the red
short indicators came on on one booster box. After a search, no shorts
could be discovered. Then all lights on the booster box went off.
Despite turning off all power and re-booting, the booster did not come
back on. A meter shows power to the input terminals.
Does anyone know what, if anything, blows out internally on these
boosters. Can they be fixed? Or am I, not for the first time,
overlooking something obvious.
If you get no lights and you can measure power at the input terminals,
then something has gone wrong.
Although System One (Wangrow) is out of business, service can be
obtained. Karl Kobel of System One stated that Ron Sebastian of
DesPlains Hobbies has agreed to be the repair depot of existing System
One equipment.
Suggest people give him a call to check out the service.

Do not contact NCE (North Coast Engineering) for repair. They have NO
obligation. legal or otherwise, to support System One. The two
companies are seperate entities.
If you wish to purchase replacement equipment, NCE would be your only
choice. However the replacment product will not be the exact same
product.
You can get more information about System One from the
group.
