If anyone is interested I have four of the same make "Cebek" timer modules in stock which are actually the 2 to 45 minute unit http://www.quasarelectronics.com/ci0002.htm I could change the capacitor to give a longer timing range if required. All brand new £8 each inc p&p Further to my retirement I have a load of boat related components if anyone is interested. Galvanic Isolators, Battery Terminals, Heavy Duty Solenoids (12 and 24v), Crimp Lugs, Cable etc. Drop me a line if anyone has particular requirements. -- Richard
