How are you managing to double the voltage using a bridge rectifier?

You don't know!!!

Don't be ridiculous; I'm just interested in how _you're_ managing to
do it.

Same way as all those PC PSUs (and loads of other things) that have 2
electrolytics in the rectifier/reservoir and a 110/230V jumper link.

So you're wasting two diodes and a switch?

I don't think you've quite recovered from being dropped on your head
(several times!).

You'll be in 6th grade next year, huh?

There was a very strong temptation not to dignify your idiotic comment with
a response, however since you appear to be an absolute novice I will try as
hard as I can to educate you.

It started off as a plain bridge rectifier, but I used a "trick of the
trade"

---
The Delon circuit.

of adding voltage doubler capacitors - although the SLA battery will
prevent it actually doubling, in trying to do so it will force the
alternator to push more current.

---
Think so?

Why not measure it and find out for sure?
