2022年4月11日 · Does anybody have any idea why my refurbished Denso alternator has twelve diodes, whereas the original had six? It works fine, but I'm mystified how a three phase alternator even uses twelve diodes. Does anyone have a schematic or an explanation.

2017年5月21日 · If only one diode shorts, you can cut it and it's pair out and still get 2/3's output. If two different winding diodes fail, it's a lost cause. You alternator has three windings. There are a pair of diodes on each winding, one up, one down, so you get clipped dc output on both halves of the sine wave that winding puts out.

2021年11月15日 · The Alternator rectifier has more than one diode. More often than not, the alternator rectifier has six diodes. The six diodes are mounted in a heatsinking material to protect them from burning up.

2022年12月27日 · Alternator rectifiers have more than one diode. Typically, alternator rectifiers have six diodes. The six diodes are housed in a heat sink material to protect them from burning out. Voltage regulators come in a variety of shapes and sizes, depending on the supplier and the model of alternator.

The BRIDGE RECTIFIER consist of six diodes, one pair for each winding. One of the pair is for the negative half cycle, and the other for the positive half cycle. As a result of this diode rectification, the output of the alternator looks as shown in figure 4.

The average alternator has 6 diodes in the alternator. The Quicktifier 420 has 12 diodes so if you add that to an alternator that already has 6 diodes you end with a total of 18 diodes. You can imagine current will pass through 18 diodes much easier than it can 6 diodes.

2020年1月31日 · Leaky or shorted alternator diodes can cause rapid changes in the output voltage of the charging system. In addition, bad diodes can also allow current to leak from the battery back through the alternator to ground.

Understanding the Alternator • Two diodes are connected to each stator lead. One positive the other negative. • Because a single diode will only block half the the AC voltage. • Six or eight diodes are used to rectify the AC stator voltage to DC voltage. • Diodes used in this configuration will redirect both the positive and

2007年7月20日 · How do you check the diode of the alternator? There will be more than one diode. They are set up in a bridge rectifier arrangement. Most of the ones I’ve seen have 6 diodes arranged to rectify a 3 phase current. If you have the alternator running you can see the excess ripple caused by a bad diode with an oscilloscope.

2010年8月29日 · Does anybody have any idea why my refurbished Denso alternator has twelve diodes, whereas the original had six? It works fine, but I'm mystified how a three phase alternator even uses twelve diodes. Does anyone have a schematic or an explanation. Thanks. It could be that two 1A diodes are cheaper than one 2A diode. Cheers. Greg Locock. New here?
