[Diy_efi] DIY-WBO2 circuit improvement suggestion

[bcroe at juno.com]

A 12 - 14V input doubling converter might put out up 
to 28 volts.  There are several parts in the DIY-WB that 
could not withstand that stress.  For example there 
are 18 V clippers intended to limit spikes, but now they 
would be on all the time and burn up.  A separate 
reducer could be built to come back down, but now 
your simplicity is gone.  Bruce Roe
