You need to check the volatge at the actuator when it is running. If it drops a lot when it runs then you need to add a relay box/accelerator. I think Eddie Marine makes one or you can wire up your own with 2 DPDT relays. This way you can use heavy gauge wire from the battery to the lift and get virtually no voltage drop-voila, fast lifting.

CP makes a relay box, get it.

yup ....

my hatch actuator is 19 ½” when closed. I think this is the one that is listed as the 12”. Unfortunately the one you have I can’t help you out with. If I talk to anyone that needs the one you have I will pass along your name.


I had a friend recommend taking it to a local company that specializes in electric motors. I had them check it out and it was pretty wore out. They rebuilt it, so this weekend I will be reinstalling and let you know what I find. Using a relay setup sounds like the way it should be set up from the factory :rolleyes:

Again thanks for everyone’s help. :drink:

insptech is right. check the voltage at the lift motor when it's running. If it's low however the most likely reason is a cooroded connector, switch contact, fuse holder or wire splice on the way from the power to the actuator. Fix that and you may be set. A relay box would do the same thing by bypassing old cooroded wiring. It dosen't take much corrosion at that current draw to result in a significant voltage drop.
