Hai... What the difference btwn diode 4001.4002.4004? From this web, it suggest using 1amp 4001....What happen if Im using 1amp 4002? What the difference... Thank you

https://web.tiscali.it/theking82/datasheet/1n4002.pdf Diodes Is a parameter of a diode that defines the largest reverse voltage potential that can be applied without causing an exponential increase in the current in the diode. As long as the current is limited, exceeding the breakdown voltage of a diode does no harm to the diode. In fact, Zener diodes are essentially just heavily doped normal diodes that exploit the breakdown voltage of a diode to provide regulation of voltage levels.

you should be fine. Only thing I see is that the break down voltage will be at 100 volts instead of 50 volts

The higher the last number, i.e. 4001, 4002, 4003, ...4007, the higher voltage capacity the diode can w/ stand. However the average current those series diode can handle is 1.0A, but it can handle at a higher current during surge(instantaneous jolt of current).
keep in mind, 1A max for isolating your currents. It means that you can NOT use it on high current wires such as ACC, STARTER, IGN
