Convertible Power Top Blowing Fuses

Q: Convertible Power Top Blowing Fuses

I have recently been blowing fuses when I put up or down the power top. It is now taking 2 fuses to put up or down. It goes about 1/2 way (in either direction) then blows. If I am quick I can change the fuse before it collapses to its previous position. With the new fuse in I can then usually get the last part of the movement completed but it oftens blows again. I am not familiar with the power top as our other cars is manual. What can be causing the “burn outs” and should the top collapse back to where it came from or is the hydraulic system a problem also. What is the possibility it is short of ???hydraulic fluid ??? which is causing the pump to over draw and blow the fuse?

A: You should probably pull the back seat to access the pump and see if it’s overheating a lot when it’s running. Maybe the internal motor is going out and blowing the fuses once it starts to overheat and draw too much current.

The repro houses have the pump for about $200.00

It’s a simple system so there shouldn’t be too much to troubleshoot.

A: I have had some “power drain” when lowering my power top, but I have yet to experience what you have explained. I would suspect that the wires leading to the pump might be suspect. (I have run mine with very little fluid and too much fluid… no problem with the fuses.) Again I would suspect the wires/pump.

A: ur 1969 does the same thing, except that I can hear that the pump is low on fluid. If I help the top along, it won’t blow the fuse, but the minute I let off, it will blow. I have a leak in one of my cylinders. If I top off the fluid, it fixes it. Maybe one possibility to check.
