Vert top won't go up

How do I troubleshoot my top mechanism? It went down fine and won't go up. I hear a 'click' from the pump relays or whatever they're called when I activate the switch either way. The seat's out, and the click stopped after I unhooked one of the linkages (either up or down, the one closer to me) by the pump.

Thanks

Since you hear the relay clicking then I'd say to check for power at the connector that goes to the pump motor. If you're getting power there and the pump still isn't kicking on then you've got likely got a bad motor. Just for the heck of it check the hydraulic oil level because I'm not certain if there anything built into the system to kill power to the motor if the oil level is low.

Thanks for the reply. Great diagram. I have the motor out of the pump assembly. LOTS of black dust (dried out seal?) Shot the windings and shaft w/brake cleaner, then immediately with bike chain spray lube. One of the brushes is about 1/3 the thickness of the other, about 1/32" thick.
I also put the voltmeter in the connector to the motor - big # one way, big negative # the other.

How much should a rebuild of ths motor cost? Can I do it myself? Or am I better off buying a new one?

Thanks

Also, my pump seems to have only the big 11/16" plug in the center of the pass. side end of the housing. There's no other place to add fluid. Sound correct or not?

I'm not certain about adding the fluid. There should be a plug somewhere toward the top of the pump I believe.

As far as I know you can't rebuild the motor yourself. You have two options. You can just buy a new one ($250 Here) or you might be able to bring it to a local electrical motor repair shop and they can rebuild it. How much it costs for them to rebuild it depends on how worn out certain parts are. However you can usually bring it to them and get a quote first.

I have a rubber stopper plug above the 11/16" bolt. That's probably it.

I called around to electric motor shops and - surprise surprise - they're not open. Lazy motor guys, at home with their families just two days after Thanksgiving! And on a Saturday no less!! HaHa. Guess I'll just have to wait till Monday, I'll post updates.

Thanks again for the info/support.
