Wiring/battery terminal heating up

Recommended Posts

In working to resolve a problem where our '92 V6 auto cuts out we have established the coil pack was faulty. Next with the fan blower and headlights on the battery terminal and one of the thick red wires heading to the teminal are heating up. The fault appears to e on the thick red wire that runs to the rear of the fuse box. There is no fuse on the wire near the battery - should there be? The wire seems to be corroded slightly but even when cleaned under load it becomes warm. Is this a known fault? any thoughts solutions appreciated.


I plan to refit the headlight 'plug and play' upgrade to lighten the load but still prefer to resolve this issue.
