3) Compressor drawing too much current (any way to check this, I do
have a multimeter)

You need an AC ammeter or the right adapter to handle 50 A more or
less on your multimeter. HTH

Quite an adapter to put inline w/ a conventional multimeter...

In a practical sense, unless you have a clampon meter, no, there isn't
an easy way for large currents...typical VOM's are able to handle only a
few 10's of mA.

Some do have a 10A range (with a separate jack). I used to use that
frequently to measure the current use by 120V appliances.

Question: are the clamp-ons at all accurate, or are they
(sometimes) GROSSLY wrong?


Even the $12 ones at Harbor Freight seem to do a pretty good job.

EG I got a radio shack 2part vom that had a plug-in clamp-on
coming with it. (maybe $30 when I got it 3 or so yrs ago)
