Onan 300-4563 PCB for PowerCommand CCM. If you're looking for a complete CCM for a transfer switch, I have that listed with this board included at the time of this listing.

There is a very good chance that this is a new, pull-off...it is very clean which is unusual for boards that have spent any time in the field. However, it does have screw marks so I'm charging the pull-off price.

This is a good pull-off. All pull-offs are guaranteed to arrive in working condition. In many cases they are never-used parts that were installed on units where the spec was changed. In other cases they were used for very low hours in testing/engineering. All are tested before being placed in storage.

While we do guarantee that all of our boards and other electronics are in good, working condition, we do not allow returns without a reasonable explanation of how the board was tested. We are fair and reasonable people. However, we can not afford to finance DIY trial and error repairs. Remember, bad electronics are frequently a symptom of a larger problem.

Standard shipping on all small items is USPS Priority. Larger, heavier items will be sent UPS or DHL ground. Items are picked up Monday, Wednesday and Friday by our shipping service, and ship the following business day. I can always expedite shipping at your cost or using your shipping account to save you money--just contact me to make arrangements.


NEED OTHER ONAN/CUMMINS PARTS? This is a part time business for us. What that means is that at any given time we have thousands more part numbers than we have time to get listed. We are slowly working on a formal inventory, but for the foreseeable future there will be many that are simply organized by type or the generator/engine they were used on. We also have many partial and complete units for pulling parts. If you are looking for something, knowing the model and spec of your unit is essential to me finding it as quickly as possible. Please understand that two of our warehouses are more than an hour away and many items require the assistance of my business partner, the owner and expert, to locate and/or remove. While we can sometimes quickly obtain items for an emergency situation, but our current arrangement works best when low price is more important than expediency.
