DH4/4C Questions & Answers
As our support team fields more questions from our customers, we'll curate a list of Frequently Asked Questions and display them here for your reference. In addition to our FAQs, we also have a DH4/4C Knowledge Base. KB articles are written to provide troubleshooting instructions for commonly asked technical questions, where as FAQs typically don't have detailed instructions or troubleshooting steps.
FAQs
Operating voltages are as measured at the terminals of our equipment and not at the terminals of the vehicle battery. There is always some amount of wire and cabling between the battery terminals and our powered equipment.
The length and gauge of that wiring is not something we can control and there will always be some voltage drop depending on those factors. As such, voltage measured at the terminals of our equipment will be somewhat less than that measured at the battery terminals. If voltage drop is greater than expected, consider increasing the wire gage or shortening the wire length or both.
