I don't agree with the partial recharge approach, not sure what this buys you if you don't have gauges and if the system isn't under full pressure? Plus, wherever you take it they will have to evacuate it in order to correctly measure the refrigerant charge, so $25+ can of refrigerant down the drain.

If you want to do a just a basic leak test, I suggest vacuuming it down to full vacuum (29hg) and leaving it for 12-24 hours, but again you need a vacuum and gauges. Best thing to do otherwise to ensure success is use new o-rings, oil them properly and torque the connections properly. I found the torque specs published in the service manual somewhere. It is VERY difficult with where some of the connections are, but I got pretty close using a standard torque wrench and some crows foot attachments.
