The diode is a IN4001 from Radio Shack @ 2 FOR 99 cents....
Each diode drops around 1.4 volts, so two would be almost 3vdc...
We have just been using one and works fine..
If your ignition REQUIRES 4.8 than I would use a regulator...

Every 1N4001 through 6 series diode I have ever used has dropped .7 volts. I'd really like to see in one drop 1.4 volts.
Just my experience.
