Expert Answers about Voltmeters


  • Recommended Wattage Consumption Meter For An RV
  • The Power Watchdog Bluetooth Voltmeter - 30 Amp # HU37FR is going to be your best option for tracking energy usage of your RV as the only other meters we carry will only give you a direct reading at that moment and isn't going to offer you a kilowatt per hour reading. The free smartphone app for iOS and Android connects via Bluetooth to monitor your system and quickly pairs using the QR code on front of device. It reads volts, amps, and watts in real time to keep an eye on your power...

  • Recommended Dual Voltage Gauge with 52mm Diameter
  • The Redarc Battery Voltage Monitoring Gauge - Dual Voltage - 2-1/16" Diameter # 331-G52-VVA is the closest we carry to what you are seeking. It will monitor two 12 volt batteries and the gauge diameter is the 52mm so it will fit without modifying the dash. The manufacturer however states it is not suitable for marine environments so it is not a sealed gauge. We don't carry anything that is water tight for that application, so if you are concerned about water in the gauge we don't have...

  • Way to Test Trailer Battery Before Trip
  • Do you mean to check to see if it's charged properly for a camping trip? If you have access to a voltmeter you could check to make sure it's at or near 12 volts. For a charger that has a maintainer that you could leave on the battery at all times the CTEK part # CTEK56353 would ensure that your battery is always topped off and ready to go.

  • Testing Battery Charger of Progressive Dynamics PD4060K and Replacing Converter
  • If put a voltmeter on the leads that run to the battery you should see the voltage increase when the converter is powered. To replace just the converter section of it you'd just want the part # PD4060CSV and you'd be set. It's not a difficult install at all.

  • Comprehensive Vehicle Side Trailer Connector and Wiring Tester
  • Most of the vehicle end trailer connectors we have will test for voltage on the circuits. If there was a short to ground then all of the lights would light up on the tester and you would know there is a problem. We do have a comprehensive trailer side tester, # 8010, which goes much further than any of the regular testers like # I26. But it is not designed for the vehicle side. For the vehicle side we have # HM50918 that can test multiple connector types on a vehicle (4-Flat, 6-Way round,...

  • What Does Not Operational Low Battery Message of Roadmaster Even Brake Mean
  • I spoke with my contact at Roadmaster and he said if your battery is reading 12 volts you will want to test the 12 volt outlet that the remote is plugged into with a voltmeter. He said on the Roadmaster Even Brake System, part # RM-9400, the remote needs to be receiving 12 volts for the unit to be working properly. If it is receiving less than 12 volts through the outlet it will give the Not Operational - Low Battery message. If the 12 volt outlet is not showing 12 volts you will need...

  • How Many Charging Volts And Battery Banks Can The Progressive Dynamics RV Control Center Handle
  • A Charge between 13.8V and 14.7V is enough to charge any battery without causing damage. A battery will only sustain damage if the charging voltage used it higher than the full charge voltage of the battery. The Progressive Dynamics RV Power Control Center with AC/DC Panel and Converter/Smart Charger - 35 Amp # PD4135K can charge multiple batteries that are banked in parallel. Renogy 100AH Lithium batteries are able to be banked in groups of four.

  • How To Determine Which Solar Charging Kit Is Right For Freedom Elite 23H On Ford Chassis
  • Determining the correct Watt solar panel to get for your Freedom Elite 23H On a Ford Chassis will be dependent on how many amp hours per day you are using based on your camping style. The best way to determine this is by taking you Freedom Elite camping and monitoring your power usage by checking your voltmeter or battery monitor while camping as you normally would to get an accurate reading of how much power you truly use per day. Once you know the amp hours you are using per day, you...

  • What Amperage Draw Does Brake Controller Look for on Trailer Wiring to Sense Connection
  • Easiest way to fool a brake controller into thinking a trailer is connected is going to be by installing a brake magnet on the circuit as that's the "draw" it's looking for. For that you could use the part # AKBRKR-M12 and you'd be set. The minimum ohm resistance you'd want is 7.5-8.2 ohms which is the normal resistance found on a trailer with the smallest brake magnets offered. If you went the diode route that would be the size you'd need. I attached a link to a help article that has...

  • Replacing 7-Way of Utility Trailer that Has Two Power Wires with RV Style Connector
  • It's not uncommon for a heavy duty trailer wiring setup to have two 12 volt accessory circuits. If you have a circuit that is hot all the time as well as a circuit that is powered only when the key is on you can decide which you'd rather have for your trailer wiring. You're on the right track testing everything to determine the function and then use the attached diagram for wiring up the new 7-way.

  • Troubleshooting Low Brake Output Brake Voltage on a 2007 NU WA HitchHiker 34 5th Wheel
  • It sounds like there is something wrong on the brake output circuit of your trailer. The reason I say that is because you have 12 volts at the connector on your 2008 Ford F350 brake controller but somehow only 3 volts are making it to the brake assemblies. Since the brake assemblies are brand new that eliminates them from being the problem. What I would do is start at the back of the connector with a voltmeter like 7-Function Digital Multimeter # PT89ZR and test the circuit for 12 volts...
