Next, to determine if the circuit breaker is operating, connect the positive lead of the tester to the switch feed wire terminal<br />
"B" of the circuit breaker and ground the negative lead, as shown below in Figure 3.<br />

A current flow should register if the circuit breaker is operating. Sometimes, the power window, or power seat, switch may<br />
be at fault. On the back of the switch, using an individual window switch as an example, will be three terminals. These terminals will<br />
be marked "BAT" (battery), "MOT" (motor), and "CYL" (cylinder). The center terminal is typically the "battery," or feed, terminal.<br />
You can test the operation of the switch by disconnecting the wires and using a simple ohmmeter. Place the 2 leads of the ohmmeter<br />
between the "BAT" and "MOT" terminals and push the toggle switch in the upwards position. If the switch is okay, you should get a<br />
reading on the ohmmeter. Use the same procedure to check for continuity between the "BAT" and the "CYL" terminals. Another<br />
simple way of testing the switch, with all wires connected, is to place a jumper wire between the "BAT" and "MOT" terminals. If the<br />
circuit and switch are okay, the hydraulic motor should start. When placing the jumper wire between the "BAT" and "CYL"<br />
terminals, you should hear a distinctive "click", which is the cylinder solenoid operating.<br />
As with most everything made in "the good old days," these switches can be disassembled for cleaning or repair. They are basically<br />
a toggle with return springs and copper contacts. If the spring(s) or toggle assembly are not broken, you can usually restore these<br />
switches to operating condition simply by cleaning the copper contacts using 600 grit wet/dry silicon carbide sandpaper or a good<br />
commercial electrical contact cleaner.<br />
In addition to the electrical system, it is imperative that all windows, power seat, and convertible top mechanisms operate freely by<br />
hand with no binding or obstructions. Clean and lubricate (I use white lithium grease) all pivot points on the frameworks containing
