The Relay Adapter Kit, No. 190-5, from Electronic Specialties includes two relay adapters for use with 190 Relay Buddy tester. These two adapters permit testing of two new relay types commonly used on fuel pumps and other powered devices. The adapter plugs into the Relay Buddy tester first, then the relay plugs into the adapter. From there, normal testing procedures are followed. This kit can be used with the 190 Relay Buddy in order to increase testing coverage, or a complete kit with all the available adapters, the No. 191, can be purchased.
