Model 360 G-MAN® Onan® RV Gen Set Service Tool
The G-MAN® is a portable piece of test equipment that will help generator service technicians drastically reduce troubleshooting time. It does this by pinpointing problems and eliminating time-consuming guesswork.
The RV gen set troubleshooting process is complicated by the fact that most modern RV controls prevent operation when there is a defect. While this is desirable for safety and protection of the equipment, it makes troubleshooting frustrating and difficult. Often, a technician is forced to become a "parts changer." This approach can run up the bill pretty fast and is not effective for certain kinds of defects.
What makes the G-MAN® unique is its ability to plug in to the generator's control system and become a part of it, instead of being a circuit board or component tester. This technique, called testing by exception, lets the G-MAN assume and emulate the functionality of the part of the system being evaluated, even if defects are present.
In addition to emulating the functionality of potentially failed components, the G-MAN provides access to 16 key points so that voltage and resistance measurements can be made safely and easily. The G-MAN can also test generator windings for continuity & grounds, something a meter alone cannot do.
The G-MAN® is housed in an attaché-style carrying case along with its test harnesses and operating instructions. It is backed by a 2-Year warranty. By means of interchangeable control board adapters, the G-MAN® can test over 35 of the most common Onan® RV Gen Set Models and their various spec levels.
