Stevens AT-100 circuit analyzer and test leads
As stated in Service Bulletin #SB-832 on the subject of 'Trouble shooting the a.c. charging circuit', we hereby announce the Stevens a.c.-d.c. circuit analyzer model AT-100. Although it was designed primarily for trouble shooting the electrical and charging circuits of the 75 h.p. alternator equipped engines, its versatility also extends its usefulness to trouble shooting electrical and charging circuits of electric-starting magneto equipped engines as well as boat and accessory circuits.
Additional features of the instrument include: 1. Individual high and low range ohm scales for measuring resistance and making continuity checks on wires, fuses, light bulbs, rectifiers, etc. 2. A d.c. voltage scale capable of measuring up to 20 volts direct current. 3. A special scale for setting breaker points and timing ignition systems.
The instrument's portability and versatility make it an invaluable aid to dealers in checking electrical systems.
This analyzer is available only from the STEVENS EXPERIMENTAL COMPANY, 2015 Grand Avenue, Waukegan, Illinois, their part number AT-100, at the net unit price of $29.75 f.o.b. Waukegan, Illinois. (Illinois resident dealers add 3½% state sales tax.)
Do not order these circuit analyzers from Johnson Motors, Outboard Marine Corporation's Parts Depot, nor from your parts distributor.
