These type are mostly used in automotive applications. You can use any 12-volt DC resistor, provided the values are the same. The rivet has to be drilled out, and then replaced by the correct resistor. You need to exercise caution when you remove the circuit board, as this is a vulnerable component. To access the resistor, it may be necessary to disassemble the converter box. Make sure the batteries are being fully charged, as a low charge would give a reading out of this range. This will be determined by the charge present in your battery. Some models have it riveted to the converter box, and its reading should be in the range of 3-13 volts. In some of the RV power converters, a resistor controls the voltage to the batteries and the 12-volt DC system. The Resistors and Circuit Board of an RV Power Converter.Make sure that the thermal sensor is working properly before determining that you need a new fan. There is a thermal sensor for switching the cooling fan on and off, which is dependent on the operating temperatures of the various components of the RV power converter. After connecting the RV power converter to the power supply, proceed to check if the voltage, at the point of entry, is in the range of 108-130 volts, as any reading within this range will be okay. The recharging ability of these batteries should also be inspected by the aid of a multimeter, to determine if any of them are losing charge over time.įirst of all, determine if the RV power converter is the component which has malfunctioned in the system. It is recommended that you inspect the batteries individually, to determine if they are fully charged. There are also instances where one bad battery will draw charge from the normal batteries, and then cause these to fail at the end.The reason for this, is that the RV power converter works in a way that maintains a constant supply of charge to the batteries, and this will be determined with the amount being drawn from the 12-volt DC system. The problem may be in the background, and may not be manifested until all the 12-volt batteries are completely exhausted of their charge.You may also encounter scenarios in which the supply power is present, but in inadequate amounts for normal functioning of the 12-volt DC electrical system. Failing to function due to a complete lack of power.
