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.
