    Hi everyone,

    I am building a system to auto dispense a small amount of chain oil to keep the chain on my motorcycle lubricated.

    So far I have decided on the type of pump and have ordered it you can see it here.

    And this is the controller I chose at this point that is adjustable from 1 to 300 seconds. It has two pots so I can adjust how long it pulses the motor for which I imagine will be no longer than 1 sec every 2 mins.

    I have a 12v source wire that lights up a bulb to tell me the bike is in neutral. I want to use this wire as a signal to start the timer circuit operating the pump. I need to buy or make a small circuit that will NOT send power to the timer when the neutral wire 12 volts then allow it through when there is 0 volts.

    Looking for a simple small design that i can put near the timer board and tape them together so it is one compact module.

    Need help... thank you everyone.

    The pump you chose is 6V but you have a 12V system. I didn't see the current draw listed either. Are you sure it'll stand up to oil? Some plastics soften to oil exposure.
