BG’s COIL TESTER MAKES TROUBLESHOOTING EASIER. . .
BG’s CT300 Coil Tester is a portable instrument designed to check the condition of the primary and secondary windings of a capacitor discharge coil. The unit is powered by four “C” size dry cell alkaline batteries. The primary voltage is adjustable from 0 to 300 volts DC. The spark gap tests the secondary output of a coil at 28 to 30 KV. The basic system includes a set of ignition leads to test unshielded capacitor discharge coils. Optional leads are available to test shielded coils. Complete instructions, including voltage settings for various manufacturers’ coils, are provided.
- PORTABLE – Allows on-site troubleshooting.
- COST EFFECTIVE – Pays for itself in “saved” coils and reduced downtime.
- EASY TO USE – Complete instructions provided.
- INCLUDES CABLES*, CARRYING CASE, AND BATTERIES – Optional leads available for shielded coils.
*[Primary lead P/N 22185 and Secondary lead P/N BG296-36 (24157-36)]
