My 89 top stopped working .the relays click but it doesnt go up or down.I have an extra motor and another convertible.I took my extra motor and hooked it up to my battery charger.it runs .I checked power from the relays to my motor and do have power going thru them. I tried my extra motor in my working mustang and it did not work in that car either.it does work on battery charger though.I grounded the motor in the car but not on the battery charger,any ideas
