The shunt should short-circuit the bell during rotary dialing, so that the bell doesn't jingle as you dial out.
Disconnect the power source.
Replace the vent valve. Repair open, short, or resistance problem in the control circuit. Repair an open, or short, or resistance problem in the power circuit, or replace the PCM.
A fuse blows when there is a short circuit or an overload in the circuit.
You need to find the short circuit in the wiring.
A short circuit in the wiring or in the switch.
Since a short circuit is, essentially, a zero impedance connection between nodes, the current in a short circuit is limited only by the ability of the source. In the case of an ideal voltage source connected to an ideal short circuit, you would have infinite amperes.
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?
The circuit voltage is too high. Could be a failed sensor, wiring short, or PCM problem.
There is a problem with the radio itself, or there is a short in the wiring, or that circuit is overloaded.
ANYTIME a fuse "blows out," and ESPECIALLY if it continues to do so when replaced,indicates a serious electrical problem. Fuses are designed to "blow" for one reason, and that is to protect the conductors [wires] in that circuit from damage or from the possibility of igniting a fire due to an overload or SHORT CIRCUIT. If you have not added more "stuff" [like sound systems, etc.] to that circuit, then the problem is not an overload, but a SHORT CIRCUIT fault. The fact that your "number 9" fuse continues to blow when new ones are installed is a clear indication of a SHORT fault in THAT specific circuit. The fact that the instrument cluster lights up indicates that it is not on that circuit [# 9 fuse], and is therefore immaterial to finding a solution to the problem. The fact that the tachometer/speedometer DO NOT work tells us that the SHORT is somewhere in the wiring, instruments, or devices IN THAT circuit. In order to correct the problem, is necessary that you FIND the cause of the SHORT circuit, and eleminate it. Then, a replacement fuse should not blow, and the instruments/devices on that circuit will again work. Good luck ! j3h
No. A short circuit would be zero ohms.
