If alternator diodes fried do you change entire alternator?

Whether or not you need to replace the entire alternator depends on the extent of the damage. If only one or two diodes are fried, you may be able to get away with replacing just the diodes. However, if multiple diodes are fried, it is likely that the alternator itself is also damaged and will need to be replaced.

Here are a few factors to consider when making the decision of whether to replace the diodes or the entire alternator:

* The cost of the diodes vs. the cost of a new alternator. If the cost of the diodes is significantly lower than the cost of a new alternator, it may be worth it to try replacing the diodes first.

* The condition of the alternator. If the alternator is old or has other problems, it may be time to replace it anyway. In this case, it would make sense to replace the entire alternator rather than just the diodes.

* Your mechanical skills. If you are not comfortable working on electrical systems, it may be best to leave this job to a professional. Replacing diodes can be a tricky job, and if done incorrectly, it can damage the alternator or other electrical components.

If you are unsure of what to do, it is always best to consult with a qualified mechanic. They can assess the damage and recommend the best course of action.
