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 ˝” 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

Again thanks for everyone’s help.

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.
