A bad engine/gearbox earth strap will cause the heater, choke and
accelerator cables to get hot but not 'fry' them in the same way that
electrical wires do when they short, and it won't cause the heater cable
to become disconnected. In theory the temp gauge capillary would be
affected as well but I've never heard of it. You would be unlucky for a
disconnected heater cable to cause a short, most electrical connections
should be protected as there are a lot more earthed metal parts behind
the dash than just that cable. I often see the backs of bullets
sticking out of the connector sheath because they haven't been pushed
home properly, but the plastic sheaths on the connectors available today
slide and can expose even correctly fitted bullets, unlike the rubber
sheaths on originals. I did hear of someone blowing a braided clutch
hose when the earth strap failed. They had been aware of slow cranking
for a while but didn't investigate it properly ...
As someone once said "Listen to your car, it is talking to you." I.e.
get used to how you car sounds, feels, looks, smells and investigate
any changes BEFORE you get a breakdown.
