![]() ![]() There are several reasons why your battery may not charge, and most of the solutions are relatively simple. If you do not see an increase, then something is not working properly on the TBC.Battery failure is often the result of poor battery care rather than technical faults in the batteries themselves. There should be an increase in the charging voltage over the static voltage. Use the multimeter on the towed battery's terminals and read the charging voltage.Plug in the umbilical to the motorhome and the towed vehicle.With the umbilical unplugged from the towed vehicle, use a multimeter to get the towed battery's static voltage.If the fuse is good, proceed to test the TBC. Check the glass barrel fuse on the side of the TBC.If it does not, then you need to splice into the ground wire (usually white) and ground it to the chassis. Check the back of the 6-pin receiver on the towed and make sure the ground goes to the chassis. There are two types of wired light systems: the first has to be grounded and uses the existing light bulbs at the rear of the towed, the second is a self-contained loop that does not have to be grounded to the chassis and uses separate light bulbs. The TBC relies on the ground for the wired light system that gets installed on the towed vehicle to complete the charging circuit. If you do not find a hot 13+ volts, then the umbilical is bad.Ĭheck for proper ground at the towed vehicle.If you see hot 13+ volts, then we know the umbilical is good and can proceed to test the TBC.Using a multimeter, touch the negative lead to the ground pin and go around the pins.Plug in the umbilical into the motorhome's 7-pin.If you do not find a hot 13+ volts, then a dedicated 12V accessory might not be run to the 7-pin or you have a corroded circuit lead.If you see hot 13+ volts, then we know the receiver is good and can proceed to test the umbilical.With the motorhome running, use a multimeter and touch the negative lead to the chassis and go around the pins on the 7-pin receiver at the bumper of the motorhome.Test for 12V at the bumper of the motorhome You could have a bad cell in the towed battery, to much current draw from not pulling fuses, 12V might not be running from the motorhome batteries to the 7-pin at the rear bumper, there could be a blown fuse, or the Towed Battery Charger(TBC) could be defective. Why is my towed battery dying even though everything is hooked up and installed correctly?Ī. There can be a few reasons why the battery is dying. The easiest way to do this is with 2 of our Towed Battery Disconnects. Failure to do so could cause damage on the towed vehicle. If you have to disconnect the towed vehicles battery for towing, then it is recommended to disconnect the negative and positive terminal. What if I have to disconnect the battery on my towed vehicle for towing? How do I install the Towed Battery Charger?Ī. In many cases the Towed Battery Charger will provide enough charge to overcome not pulling certain fuses. Does the Towed Battery Charger keep me from having to pull these fuses?Ī. We always recommend that you follow what the owner's manual says to do for towing. My towed vehicle's manufacturer requires that I pull fuses for towing. ![]() ( NOTE: We recommend or for help creating a second umbilical. The Towed Battery Charger cannot get a hot 12V from the motorhome through a 4-pin umbilical. In order to bring the correct 12V to the bumper of the towed for the Towed Battery Charger to tie into, you'll need to either: I have a 4-pin umbilical, will the Towed Battery Charger work?Ī. When the Towed Battery Charger is installed, the motorhome is running and the umbilical is plugged in, the towed battery stays topped off. A 6-pin umbilical has the 4 pins you need for the light system, as well as a pin for electric brakes and a 12V hot pin. The Towed Battery Charger is specifically designed to work a 6-pin connector on the towed. How does the Towed Battery Charger charge the battery?Ī. For a frame of reference, your brake lights pull 4 amps. All models of RVibrake are extremely power friendly. The max amp draw of RVibrake is 8 amps. If I own an RVibrake is a Towed Battery Charger required?Ī. No. No more need for a charge line that gives you zero feedback. It is a great peace of mind product when towing. The Towed Battery Charger will prevent unseen parasitic loss on your towed vehicle battery, while giving charging feedback. Many towed vehicles today have a large current draw on the battery when towing. There are not many things worse than a dead towed battery. Why do I need the Towed Battery Charger?Ī.
