ABOUT THE BUZZAROUND XL™ SERVICE GUIDE
This service guide provides you with the information necessary to troubleshoot the Golden Technologies Buzzaround XL
GB117/GB147. The troubleshooting scenarios in this manual consist of procedures that enable you to systematically trace
and correct faults in the system. Appendices A and B include instructions on how to measure voltage and continuity with
a multimeter.
Before troubleshooting, check the following:
Make sure that the circuit breaker is reset.
Visually check terminals for corrosion. Check wires for missing insulation.
Make sure the battery terminals are securely tightened.
Make sure that the batteries are fully charged and are in good working order. When possible, keep sets of
known good batteries of various ratings in your shop at all times. The Buzzaround XL uses either two (2) 12AH
or (2) 22AH batteries. Problems that surface during troubleshooting are often due to the fact that the batteries are
not fully charged or can not hold their charge.
Make sure that the electrical connections are secure. Unplug the connectors and make sure all the pins in the
connectors are seated securely. If necessary, push any unseated pins back into their connector housings to securely
seat them.
If you get to a point during troubleshooting where you cannot continue, call Technical Support
at 800-624-6374.

breaker will open.
Connections: The circuit breaker is connected to the positive (+) terminal on one battery and the negative (-) terminal on
the other. (Note: Both circuit breaker wires are orange in color.)
Failure Signs: Opens repeatedly. May indicate failed circuit breaker or short in the wiring. May also open if the motors
are overloaded (from excessive weight, excessive uphill driving, etc).
Test: Measure the resistance across the circuit breaker and the wires that connect the circuit breaker to the batteries.
Expected reading: Less than 10 ohms.
Serviceable: 30amp circuit breaker must be replaced with exact current rating.
