Controller | Quick Reference
R1, R2 3.3K
ZD1, ZD2 5.1V
R4 130 ohms
R5 8.1K or 8.2K
C is polarity specific. The + is marked
and goes toward the ZM and pot.
Set the pot from ground to middle pin at
2.7K to get it close to 14V.
Notice the IRFZ44N and dump load are connected
to the battery different than most people
guess it should be.
The controller wires and dump load wires
MUST be separate wires.
Solder in the pot and ZD1 at the same time.
It can get a little tight.
