With bad diodes, an alternator can drain a battery with the engine shut off, too. Even if it charges with the right voltage while it’s running.

My alternator was charging while engine was running, but when shut off it draining about 1.5 amps, I tried to take it apart and only change the electronic parts but could not take it apart, so I brought ine from Junkyard, and it work fine, only drawing .005 of amps when engine shut off which is normal.

@dev-debug 2 ай бұрын

@@user-tj3gm4uq4w An alternator creates AC voltage so diodes are used in a bridge rectifier configuration to convert the AC to DC output. A diode when working properly only passes current in one direction. If even just one shorts in the alternator your battery will drain because the battery will be energizing a coil in the alternator causing. There are a minium of 4 diodes in an alternator, some may have 6. They are easy to test using an ohm meter.

You can charge battery in vehicle, just do the same as I showed with battery charger. Red to positive and black to negative and double check settings if there are on your charger then plug in 👍 you dont need to disconnect any cables either just connect right to battery posts/terminals

@Powerhouse_Racing 2 ай бұрын

I was thinking the same thing, it is a complete misconception. This was from back in the days when batteries were made of wood or hard plastic, the wood would absorb moisture from the concrete and the hard plastic cases would crack when exposed to moisture from the concrete. The new polycarbonate battery cases would never be affected. Plus discharging through the concrete is ridiculous. 😂
