update
I was back in Maplins today about the voltage regulator module that I bought.
(see link at top of page as to what i mean)
The original one was not adjusting the output voltage(well it was but by about .5 of a volt)
Got it exchanged wired into Aqua techs pump box and works like a dream. Voltage adjustable from around 3 - 12v's.
And all for the sum of £14.99
Will all up to date as to its success
