You need to monitor the high pressure side as well. If it is to high the system is plugged and will blow the seals out of the compressor. Most self recharge kits only tell you the low side pressure.
I was all set to use one of those kits and after a lot more research, decided against it.
I can see using just the low side if your lucky and nothing else is going on. If your not lucky you just destroyed some expensive stuff. Since a set of gauges is only $30~$60, it doesn't make sense to me to cut corners.
