[Diy_efi] RE:Ignition amplifier Bosch 0-227-100-200

[Mike]

On the TO-3 body it has  "6513" in black print

On the aluminium bracket which its attached
to it has the Hitachi symbol and the numbers punched
"22020 - 42L10" and below that
"HANSH/N PRT-200"

It would be of some interest what the manufacturer's specs are
but have an improved module in the works with higher strike volts
and about 10% more power out and some diagnostic functions, the
replacement modules new from wholesale are around $120 to $159ea
which is naturally overprices but havent heard of an alternative so
decided to make one from up to date components and provide
some diagnostics, ie "Pretty leds that do certain things" tm
