Checked a few things 200 1989

Hi Chuck,

The trace on the main pump was identical (AC component) regardless if the prepump was bucking or aiding it. Only a small shift in voltage (DC) showed the effect of the tank pump.

I'll try to remember to hook up to all, especially since one of the turbos has a pump with only a few thousand miles on it. Sure the ratings are a bit different, but they all have windings and commutators. I read some stuff years ago about diagnosing pumps by their current signatures, but then I only had one or two 240s.

If you lend someone $20 and never see that person again, it was probably worth it.
