TankTimer Keep that bait alive!

Wiring Diagrams and Instructions

***IMPORTANT***

Ensure the power to the TankTimer is fused. (Check the pump for it’s current rating, a 5A fuse should be sufficient.) Ensure the TankTimer is wired the right way around - incorrect polarity will damage the TankTimer. The maximum current draw is 10 Amps. Make sure the TankTimer is mounted out of the weather as it is weather resistant not waterproof.

Simple pre-installation test:

Make sure your pump is still working before commencing installation. This tests your pump, your wiring and your battery prior to introducing a new device. This may save you chasing needless faults after installation of the TankTimer.

Option 1

Purchase a SPDT (On-Off-On) switch to replace your current Pump Switch. You can purchase these from any Electronic/Automotive parts supplier or from most Marine Chandlery suppliers. A preferred option may be to contact your nearest Boat shop and purchase a switch that matches your current switch panel.

Connect 12V fused power to the centre pin of the new switch. Connect the TankTimer Red wire to one side of the switch. Connect the TankTimer White wire along with the positive pump wire to the other side of the switch. Connect the TankTimer Black wire to your boats negative/earth. (There should be a terminal block behind switch panel)

Option 2

Similar to Option 1 except you do not replace the original switch. Purchase a SPDT (On-Off-On) switch and mount it separately. Therefore the power for the SPDT switch will come from the output of your current switch. This then becomes a two switch operation and you can locate the second switch in a place that suits the layout of your boat.

Connect the 12V fused power output from your already installed switch to the centre pin of the new switch. Connect the TankTimer Red wire to one side of the new switch. Connect the TankTimer White wire along with the positive pump wire to the other side of the new switch. Connect the TankTimer Black wire to negative/earth. (Should be a terminal block behind switch panel)
