I used the 10 amp maximum setting on my multi-meter to test both pumps on my 81. I hooked the leads to the two contacts where the main pump fuse goes. The main pump never registered any amps at all with the car running. What had happened is the main pump instantly blew the internal fuse of the multimeter. Eventually, I determined that the main pump was drawing over 10 amps because it blew the 10 amp fuse and the transfer pump was only drawing somewhere between .4 amps and 1 amp. I never determined what it all really means, other than that I need to get a real ammeter like one guy suggested. Any suggestions on where to buy a good meter and what brand?
