If your Power Gear reservoir and motor are in the right front of the engine compartment, like mine, there is a dipstick and fluid fill on the top left of the reservoir. There are actually 2 of them, one on each side of the top of the reservoir. The dipstick is reachable when the engine cover is open by reaching into the opening and pulling the dipstick out. You will need a flexible filler tube to rech it. The "Jacks are down" alert system is acuated if the jacks are up, but the fluid is the least bit low in the reservoir.
If the filling of the fluid does not solve the problem, it could be either a miss-aligned or faulty float valve. Easily replacable.
Hope this helps.
Happy Trails!
