Megasquirt DIYPNP Alternator board mounting brackets

thingiverse

This bracket secures the Alternator Control board firmly onto the Megasquirt DIYPNP. It also works on other megasquirts. The instructions recommend using hot glue, but I prefer a more reliable method. The Alternator Control board is necessary because the Miata NB (MX-5 NB) has its alternator control integrated into the original ECU. When swapping the ECU for a Megasquirt, the car fails to charge, so this board is required. You can buy it on Ebay under the name: "99-05 Miata Alternator Control V3.3 by Westerfield MX5". The brackets are mounted using a Zip-tie that clips into an existing hole on the main board. For the second bracket, use two pieces of stripped wire and solder them to the proto-area on the main board. Then, secure the alternator board to the brackets with M3 bolts, which can range from 4 to 9mm in length. If you printed this guide, please leave a comment below!
