dodge ram voltage gauge 18v
The voltage of the voltmeter of the pickup dodge ram is generally 14V when the truck is on, and it is abnormal when it exceeds 15V, which will cause water loss of the battery and damage electrical appliances in serious cases. If dodge ram voltage gauge 18v , please pay attention .
The battery should be 12v60ah 550a<sae>. 12V: rated voltage is 12V; 60ah: the rated capacity at 20 hour rate is 60ah; 550A (SAE): according to the SAE standard, the cold start current value is 550A. In principle, when the appearance size is the same and the positive and negative terminals are the same, it is best to install a battery with larger capacity, which is beneficial to the battery life.
The charging of dodge ram battery is divided into main charging and floating charging. Generally, the primary charging of lead-acid battery is planned to be main charging, and it will be changed to floating charging after reaching the rated voltage.
The DC voltage output is too low, and the battery voltage of electric vehicles is too high. For maintenance methods, first use a multimeter to check whether the high-voltage DC filter capacitor has deteriorated, whether the capacity has decreased, and whether it can be charged and discharged normally . If the cooling fan doesn't work, the maintenance method is to use a multimeter to measure whether the triode controlling the fan is damaged. If the triode is not damaged, it may be the fan itself is damaged. You can unplug the fan from the circuit board. In addition, connect a 12V DC (pay attention to the positive and negative) to see whether it rotates and whether there is foreign matter stuck. If the fan rotates when the wire of the fan is swung, it indicates that there is a broken wire or poor contact of the connector inside the wire. If it still doesn't turn, the fan must be broken.
High voltage of dodge ram battery will affect driving safety: generally, the voltage of car battery should be about 14V in the flameout state. If the voltage is lower than 12.5V, it needs to be recharged in time. 18V is too high, unless it is the virtual voltage detected just after the flameout. Check it after a few minutes or turning on the headlights for a few seconds, or it is necessary to verify whether the detection instrument is accurate.
