Yes, but only at a basic level. If the diode measures low resistance in one direction, high resistance in the other, you know that it is not short-circuited. But... 1. If it's a voltage-regulator/reference (Zener) diode, you do not know whether it has the correct breakdown voltage, 2. If diode leakage is important, you have not tested for leakage and the ohmmeter test does not do this reliably, 3. Your ohmmeter test voltage is probably no more than 9 volts, so you have not tested for high-voltage breakdown, and 4. If it's a rectifier (especially a high-current diode) you have not tested its forward voltage at full load current.

You can use most diodes for that purpose, and particularly silicon diodes. However, you should not use zener diodes and similar for rectification purposes. Otherwise, you will likely not get the intended result. If the voltage exceeds the avalanche voltage, then the zener diode will no longer rectify, but conduct the other way as well.
When p-n junction of a diode reversed biased then majority carriers are not able to cross the junction and are attracted in respective regions.So current becomes approximately zero.But because of minority carriers a reverse current keeps flowing.It is called Reverse Saturation Current.And due to attraction towards sides,charges go away from junction.So width of depletion reason increases.
Well, darling, the only real difference between a 1N4007 and a 1N4005 diode is the maximum repetitive reverse voltage they can handle. The 1N4007 can handle up to 1000 volts, while the 1N4005 can only handle up to 600 volts. So, if you're playing with high voltages, go for the 1N4007, but if you're keeping it low-key, the 1N4005 will do just fine. Happy diode shopping!
Bad diodes in the alternator can cause the battery to go dead when the car is off. The diode bridge (six diodes) is directly connected to the battery, and is used to convert three phase delta AC from the alternator's stator to DC for the battery. Normally, if the engine is not running, the diodes are reverse biased and do not conduct current. If one of the high side diodes is shorted then the diode trio (another set of three diodes supplying the regulator/rotor) could conduct and drain the battery. Often, a diode failure is a short or an open. A short in a high side diode along with a short in a low side diode would result in high current from the battery, and that would probably blow the fusible link. An open would result in poor performance of the alternator.
The key function of a diode is to control the direction of the flow of current. Current passing through a diode can only go one way, which is called forward biased. In this setup, current is continuous hence the circuit is closed. When there is no current passing through, there will be no flow, and this is called reversed biased. In such a case, current is not continuous, hence it is called open circuit.
Not enough information. WHICH fuse blows out???

A transistor is not a diode. It is also not a pair of back to back diodes. Two diodes connected back to back will not function like a transistor because their junctions are not in close proximity like they are in a transistor. The only reason for "thinking" that a transistor is "like" a pair of back to back diodes is for purposes of quick go-nogo testing with a multimeter, but that will only assess open, short, and leakage status, as well as polarity, but not any of the more useful things, such as hFe.
The forward biased voltage drop of a diode depends on the type of diode and the current through the diode. A typical silicon diode will exhibit a voltage drop between 0.6v and 1.4v depending on current. An LED might range from 2v to 3v. A germanium diode might go a low as 0.2v. Bottom line; it varies.
it sounds like a short in the wiring you should probably have a mechanic or an electrician test each of the wires for arcing

there are resistors located by blower motor. could be open. they control blower speed.
240mph
yea they do when one blows up a chain reaction happens earth will go second
