OK, finishing up my little project and have a question about how to determine what kind of diode I need, and whether I need two or four of them.
Basically I have a load at 100W (max 125W) / 12 V that I need to run either forward or backward. I figured I can do this with a set of relays and wiring as follows:
What I need to know is:
- What kind of diodes do I need at A?
- Do I need a second set of the same diodes at B?
