It could well be just a bad wiring moment , do you have a soldering iron, tin the ends of the wires, stop any stray threads. another culprit is the heatbed PID enabled but not configured.

cant say I had/have any issue with tinning the ends, but I aint using massive amounts of solder either, still their no excuse for not doing a proper job either which ferrules would you suggest for those ramps connector.Quote

Tinning the wire ends is bad advice and more or less guaranteed to cause problems.

The simplest solution is to avoid taking the +V line for the heat bed through the ramps. It's only there to go through the poly fuse and to my mind the benefits don't merit the heating issues. I'd recommend getting an inline fuse (for example) and running a power line directly from the power supply, via the fuse, to the heatbed. Switching remains on the -V line on the ramps. Keep the -V connections from the psu to both connectors on the ramps, that helps distribute the return current over the pcb tracks and carry the current back to the psu. With this arrangement the ramps runs much cooler.
