It is raining this morning, though pretty light.
I cleaned the topside of the engine w/Purple Power.
While waiting for the plugwells to dry so I can change the plugs, I checked on the Horn. The terminal that supplies ground had slipped off. I tightened the crimp and the horn now works.
I also checked on the a/c. The system has -some- pressure and the compressor is not locked up. This makes me very happy.
