Puretan ellipse IV HELP!!!!

[redbikes1]

Ok! I bought a 2005 ellipse IV with 700hrs on it for 1500.00.
I have been dealing with beds for 12years and do all my own diagnostics and part replacing> But this one i am stumped on. I hooked the bed up and all the bulbs on the bench work. Three bulbs and the facials work on the canopy(Thats it). I triple checked the connections to the balast tray. It's not bulbs or starters! Can anyone help!!!!! Also on my multi-meter there is voltage to the bulb sockets.
Keep in mind that none of the fans run either.

Bad connection on the plug in the drawer to the top.

Could also be a bad connection on one of the terminal blocks are the contactor.

Measure phase to phase, not phase to ground or you are just reading feedback through the components of the same phase.

That wierd stuff is why I never became an electrician. On my first car (a '56 chevy bel-aire V8) - everything could be diagnosed by hot to ground.

Now - even my silly UV meters have a "system" ground which is magically a constant 3V below battery ground.

Cannot imagine diagnosing my lcd tv sets!

Well on your car there is one hot wire and one ground. That is why you could measure hot to ground because ground is a current carrying conductor.

The bed would have two hots and one ground. Some have three hots and a ground. Ground is just for safety anyway and is not a current carrying conductor in the bed though but still references neutral when measured that way.

Choke ballasts run at 230 volts so measuring the system by referencing a 120 volt system is pointless and confusing because of feedback through other components.

My next thought was a contactor. There are four of them. I am going to see what happens when I swap it with the the bench contactor. Also the bed has a tantime timer board, and I run a t-max 3a does anyone know how to hook that up?
