| Apr 23, 2021 at 13:47 | comment | added | Cody | Awesome, thanks. Made a wiring diagram on Falstad.com which seems to be working exactly as intended, with the omission of D1. I understand the function and purpose of diodes to some degree, but could you please expand on the purpose of D1? tinyurl.com/ygckshey | |

| Apr 23, 2021 at 9:05 | comment | added | Cody | Where do I connect the bottom three (signal ground?) points? Do they go to the negative side of the relay coils? I have drawn up a rough wiring diagram to help me better understand app.luminpdf.com/viewer/60828a1eefd5bf0011d2ba28 The two loops (Forward & backward) are separated for clarity. | |

| Apr 22, 2021 at 13:00 | comment | added | Unimportant | @Cody Updated the schematic. Those relays require a hefty amount of current so I changed the switching transistor to a N-Channel MOSFET. | |

Modified schematic for relay current requirements.

| Apr 22, 2021 at 12:22 | comment | added | Unimportant | @Cody The current the relays require to operate. | |
| Apr 22, 2021 at 12:19 | comment | added | Cody | Are you referring to the current draw the coils need to operate or are you referring to the current that the motor will be drawing through the relays? | |
