200ish mA current when a zone is running seems normal. So the wiring and connection to solenoid seems fine. Two things to check first:
1. In Settings -> Advanced, check the ‘Boost Time’ option — its default value is 320ms. Has it changed?
2. Do you have a master or pump zone? If so, what’s the brand name / model number of your pump start relay? DC-powered OpenSprinkler is known to not work with all pump start relays, so if you do have one, it’s better to stay with AC-powered OpenSprinkler, or you can change your pump start relay to solid state relay which works well with DC OpenSprinkler.
