Since this is my first new clock in many years, there has been a learning curve, but so far I like it, I really like it. One thing I ran into today running amperage tests: it reads in millamps instead of amps, as do our Rain Masters. To avoid any confusion, I'll provide the following: 1000 millamps (mA)= 1 amp. Example= 260 mA = .26 amps. The mA tests I ran on our new system ran from 220 mA to 262 mA. Using our Rain Master, the same readings would be .22 amps to .26 amps. A reading in the low twenties (or 200 hundreds) would be a flag for beginning of solenoid failure, though WM, hedging their bets, say 150 to 350mA. Here are pics of version 92.5 solenoid w/"marine grade" & volcano protection.
