Hopefully, this thread can now come to an end. There is no leak in the low pressure tube that I can find at the point I suspected - no bubbles & it has held it's static pressure at roughly 60 psi , which was where it was before the past few days of trouble-shooting the blower. I did clean the connections on the low pressure cut-off switch to make sure I got a good connection.

Started her up and running low side started at 25 psi and slowly climbed to 30, where it sat for 15 minutes. I started just running the a/c on Norm with the fan speed at high. Since everything seemed to be going well, I popped it into Max. Ran like that for another 10 minutes. Low side running holding nicely at 30 psi.

Looks like my initial problems were:
1 Not enough refrigerant so the compressor wouldn't kick in. By-passed the switch and she worked fine. Added a can of R12a to get the volume up to minimum.
2 Plugged the low pressure switch back in after adding a can. Then the clicking of the switch started.
3 Then the blower quit (may have been completely coincidental).

So now, cleaned the connections on the low pressure switch in case after disconnecting it, I lost a good connection. No more clicking. Blower working well (knock wood). An air leak around the motor casing and at the cooling hose (not big, but I would like to seal those up) and the a/c blowing nice, cold air again.

Since I did lose some refrigerant over the winter, I obviously have a leak (small) somewhere. But at this point, I am going to leave well enough alone!

Thanks to all.

Next job - replace the LOP switch and oil filter adapter gaskets and starter bracket on the Onan. But those may also wait till after my trip to Washington.
