"Foaming" P/S fluid is an indication of air in the system either from a leak or a faulty pump.
If you continue to drive with low fluid and the pump is "growling" the pump will fail even if that is not the cause at this time.
Once you find and correct the problem you must bleed the system or pump damage will result.

Sounds like stray voltage looking for ground, is probably related to the T/S problem, repair that and the chiming will probably also stop.

I will check on wiring tonight.
