Engine hatch actuator (acculift)

It appears they got bought out. When I took my lift in they only had the shop in Melvindale. They rebuilt it in a couple of days and it's worked perfect since. I don't have a relay on mine, it runs straight off the switch. But the switch is rated at 20A. If you're seeing only 8.5V you have more than a lift problem.

If this is correct then you need to correct the feed problem first. It should not be dropping that low. I would go through all of the wiring and grounds and make sure they are clean and tight. Have you tried it with the engine(s) running ?
