I am working on a 89 Mustang convertible and can't get the switch to operate the top. I have power back to both relays in the trunk but nothing works. I can operate the top by running a hot wire from the battery. Any help would be appreciated

If you have a 12v trouble light. Check and see if you got power to the switch.
You can also check it from the power source to the motor at every connection. That way you can norrow it down. check your terminal end ( if your using them. If using plugs check your wire ends in the plugs. (sometimes the male part dose not make contact with the female part)

You could have a bad relay. Bench check the relay.

As soon as I get a chance I will check it out. I know that when you operate the top's switch you can hear a clicking sound in the relays.

Dave: Electricty flow is just like water flow thru pipes. The switches and relays are just like valves. If they don't open there is no flow. Put a test meter or light from ground to the hot spots in the wiring where there is supossed to be voltage. At one point you will find that it is not getting thru. The fact that you can go direct from battery to motor tells you that motors is working and properly grounded. That means your electricty is not getting thru switches and relays. GOOD LUCK DAVE E SHANK
