After double checking all installation points, it is now time to test it all out. Dave is quick to point out that both the primary and secondary batteries must be fully charged before the engine can be started. If not, the charging systems will show inaccurate readings, complicating the final process. With the motor running, a quick check of the digital multimeter shows the output of the secondary alternator at 14.74 volts. Perfecto! Again, a detailed post-installation checklist is provided by Dave's DC to help ensure that your newly installed charging system is working properly. This really takes the guesswork out of the testing phase.
