Hello,
I have several of these Micor repeaters with the TPN1105/6 battery charger
supplies running and have the solution to your problem. First, the factory
set the charge voltage at 14.25 volts since as standard equipment they
supplied NICAD batteries for backup. Naturally, this is way to high for
lead/acid. SO, all you need to do is open up the large steel plate on the
backside of the power supply and locate the Voltage adjust pot on the large
PC board, I thik it is R1091... then, without any batteries on line, adjust
to 13.2 volts. from the 14.25. Hook your batteries back up and you are good
to go!. The slide switch on the PS should be left in "FLOAT" position, if
switched to "EQUALIZE" it will add +1 Volt making 14.2, this is to allow
for quicker recharge after a battery power event, and should be reset after
24 hours to float.
Hope this all helps you.
