Hi mck. I am not 100% if I have checked in the wright wirring diagram, I checked for a automatic coupe but I dont think there is much difference in the lightning system with a manual car or convertible. In the left corner of the engine compartment, at the jumpstart connection, you will find a bunch of fuse link, if you are not familiar, it's a wire that act as a slow burn fuse. There is a few connected together. they do look like a wire but the exterior texture is more like rubber. Pull them one by one and if one is blew it will be ether burn or it will strech like a rubber band. The inside of these look like a regular wire but made of a material that look like lead. It melt easily but will accept peak of voltage without blowing as fast as a fuse. In you manipulation, you may have grounded a 12volts and blow it
.
BTW the fuse link that I think might be burn is probably a medium brown color, they call it ''rust''. If this is not the problem, I will try to help you again but I am leaving for the weekend so I will be back only Sunday or monday night.
Good luck
Stephane
